• Unity install removed window borders, and display drivers.

  - by Vivek Sharma

  I installed unity, used for a while. Then i installed gnome-shell, used it for a while. Now decided to switch back to standard. Gnome is not working the way it use to be. I am using T61 with nvidia-latest drivers. Following issues... Window borders are not showing. Installed compiz settings, and re-check window decorations option. I had to re-install nvidia driver, as when I tried to apply normal visual effects, it said no display driver found. Gnome panel is not coming, and mouse pointer is a "cross" than a "arrow". I then opened a terminal and enter gnome-panel. Panel came and window borders came back. Nothing is showing on desktop, and the right click is also not populating the menu. When i loging, an error message saying, docky did not start and it requires compiz to work. After starting gnome-panel from terminal, i went to systempreferencesAppearance. And selected normal visual effects. It activated, i selected keep the settings. Now when i restart or re-login, everything is gone. I have to run gnome-panel manually, and then re-enable visual setting. Ofcourse i can add gnome-panel in startup applications, but i want to know what has installing unity/gnome-shell has done, that these setting are messed up. I manually removed mutter, as Appearance application was showing mutter installed, cant enable effects. What shall i do to get back a standard gnome-desktop back.

Next type or copy the following path into the location field and click Next. c:\windows\system32\gpedit.msc Then give your shortcut a name…something like Group Policy, or whatever you want it to be and click Finish. Now you have your Group Policy shortcut… If you want it on the Taskbar just drag it there to pin it. And that’s all there is to it!   If you want to change the icon, you can use one of the following guides… Customize Icons in Windows 7 Change a File Type Icon in Windows 7 Add Group Policy to Control Panel If you’re using non Home versions of XP, Vista, or Windows 7, check out The Geek’s article on how to Add Group Policy Editor to Control Panel.

• Can't adjust backlight on an Nvidia 335m GT

  - by Vladimir

  I have a laptop mySN QMG6 / Chiligreen Mobilitas NW which is Quanta TW9 barebone with intel i3 and nvidia 335m GT onboard. On ubuntu distros 10.04, 10.10, 11.04 and 11.10 i had problem with changing screen backlight with nouveau and nvidia drivers. FN+F4/F5 buttons did not change my brightness. I tried to edit xorg.conf, adding Option “RegistryDwords” “EnableBrightnessControl=1? Also tried to add some lines to grub acpi_osi="Linux" acpi_backlight=vendor Neither worked for me. Today I installed Ubuntu 12.04 beta2 and... With nouveau driver my FN key works, and changes the brightness (is it a new 3.0.22 linux kernel, or patched nouveau driver, i don't know). This is a big step forward. But, when installing proprietary nvidia driver (295.33) FN button stops working and i can't change brightness. I also tried workaround with xorg and grub with no result. Tried to install acpi from apt - no result. Is there anything left to try? I really need that nvidia driver working with FN keys, as i would like to have a working 3D acceleration. P.S. Does the nouveau driver has 3d acceleration like nvidia drivers??? If there is need to provide some log data, please write what should i print, as i'm a bit new to Ubuntu. P.P.S. Same problems i had with other Linux distros (Mint, Fedora and others) P.P.P.S. Other FN buttons work with both drivers (Mute, VOL UP/DOWN, WiFi on/off, Bluetooth, Sleep, Start/Pause, Stop, Next/Prev song) Some new thoughts... CONFIG_BACKLIGHT_GENERIC=m could this be an issue? Made this by grep BACKLIGHT /boot/config-3.2.0-22-generic-pae Full grep output can be viewed here: http://pastebin.com/sMRd2Z4k

  I use Wubi to install Ubuntu 12.04 on my Windows 7 system. My PC is Acer Aspire S5-391 with a 64-bit operating system.

• Start daemon after specific samba share is mounted

  - by getack

  I have a homebrew headless NAS running 12.04. In it I have a bunch of disks that are presented as a samba share thanks to Greyhole. If I want to do anything to the files within this share, I must do it through greyhole so that everything is updated properly. Thus, the share must be mounted locally and then accessed from there if I want to work on the files from the local machine. I do this mounting automatically thanks to these instructions. I also have Deluge installed that takes care of all my torrenting needs. Deluge's default download location is in this share, so that all the downloads are immediately available to the rest of the network. Obviously for everything to work, the share must be mounted, otherwise Deluge is going to have a problem downloading to it. The problem is, it seems like Deluge is starting before the shares are mounted when the system boots. So downloading/seeding does not continue automatically after boot. I have to log in and force a manual rescan and start on each torrent otherwise all the torrents just hangs on the error. Is there a way I can make deluge start after the shares got properly mounted? I looked into Upstart's emits functionality but I cannot seem to get it to work properly. Any advice?

• How should I configure TRIM Support for LVM logical volumes?

  - by Zack Perry

  I am setting up a notebook for software demo purpose. The machine has a Intel Core i7 CPU, 8GB RAM, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit desktop. As it is, the SSD is configured to have a single volume group, with /boot, /swap, and / all in their respective logical volumes. They collectively consume 30GB space. I plan to use the remaining for logical volumes for KVM guests, all run Ubuntu 12.04 Server I would like to ensure that the SSD is utilized optimally. Although on this site, there are some great info about setting up TRIM support for file system setups that do not involve LVM, I have not found explicit guide regarding my planned setup. I did found this page which talks about adding issue_discards in /etc/lvm/lvm.conf. But in said file on my machine, I didn't find the cited content. I double-checked man lvm.conf(5), didn't see any mentioning of this option either. Thus, I'm not sure what to do. Furthermore, even say adding the option is the right thing to do, should I in my machine's /etc/fstab still add mount options such as noatime etc? Any tips, pointers, and/or further guidance are greatly appreciated.

• SQL Monitor Alerts in Outlook Without Configuring Email Settings

  - by Fatherjack

  SQL Monitor is a Red Gate tool that I have a long history with and I have worked closely with the development team from a time before it was called SQL Monitor. It is with that history in mind I am a little disappointed in myself that I have only just found out about a pretty cool feature. Out of the box SQL Monitor keeps itself to itself, it busily goes about watching over your servers, noting down when things look suspicious, change drastically or are just out and out wrong. You have to go into the settings and provide email details (SMTP server, account details etc.) before it starts getting at all intrusive with warning and alerts on the condition of your servers. However, it was after installing the most recent version that I was going through the application screen by screen looking for new and interesting changes that I noticed something that had avoided my attention. On the Alerts tab there is an option in the left hand menu. I don’t know how long ago it appeared or why I have never explored it previously but it appears that you can see your Alerts in the format of an RSS feed. Now when you click that link you are taken to a page that is the raw RSS XML – not too interesting but clearly you can use this in an RSS aggregator. Such as Outlook. Note the URL in the newly opened page take it with you into Outlook. For me it is in the form of http://SQLMonitorServerName/Alerts/Inbox/Feed. Again, this is something that I have only recently noticed – Outlook can aggregate RSS feeds. Down below the Inbox, Drafts folders etc, one up from the bottom is RSS Feeds. If you right click that and choose to Add a feed then you can supply the URL for SQL Monitor Alerts: And there you have it, your SQL Monitor Alerts available in Outlook where you can keep an eye on the number of unread items and pick them off at your convenience.

• Adding graph in excel based on the content of ADFdi Table

  - by Arun

  Often we tend to represent the data present in the table in a graphical format to give a visual impression of the data. This article would be explaining the way to achieve it using the data we have in ADFdi table of the integrated workbook. Pre-requisites: Microsoft Office 2007 JDeveloper 11.1.1.1.0 and above Assuming we are already having an ADFdi enabled workbook with a table based on an Employee table as shown in the image below. Also, add the table.download to the ribbon toolbar as menu item / as action for the startup event. From excel, we'll add a new 3D bar chart Now, we need to select the data range for the chart. We will take an example of chart based on the salary of the employees. So, the data for the X-Axis of the chart would be the Ename and the data for the Y-Axis being the salary. We can do that by right clicking on the Chart and selecting Select Data. We would select the Legend Entry Series name as the Sal header column in the table, and for the data, we select both the header row and the row below it (by holding Shift key). And, for the Category Axis, we select the Ename header row and the row below it (by holding Shift key). We can get the chart now, by running the Workbook and downloading the data into the table. This simple example can be enhanced for complex graphs by using the data from the ADFdi table to use the power of excel along with ADF Desktop Integration.

• Wubi doens't work anymore - shows 'No wubildr' error

  - by Joe

  Basics: HP Mini 311 Ubuntu netbook edition 10.04 (installed via Wubi) Symptoms: I load to Windows Boot Manager as usual. Options are Windows 7 and Ubuntu Netbook, like usual. Selecting Windows 7 does as it should. Loading Ubuntu Netbook, though, does not take me to the usual screen where it lets me select versions of Ubuntu (sorry for bad wording, not sure what the real name is called; it's where you select from about 6 items; I always picked the first due to lack of knowledge without issue). Instead it flashes an error in white on a black screen then restarts very quickly. It took me a few restarts, but here is the error: Try (hd0,0): NTSF5 No wubildr Try (hd0,1): NTSF5: Situation: I have no clue what caused it. The only thing I did last night on Ubuntu was install Skype, but the mic didn't work instantly so I got lazy and switched to Windows 7 and used Skype on there. When I tried to switch back to Ubuntu it began this. (There may be something I forget... it was 5 in the morning). There were no recent updates that I remember. No weird activity. Just... random. Help please?

• Oracle Solaris 11 ZFS Lab for Openworld 2012

  - by user12626122

  Preface This is the content from the Oracle Openworld 2012 ZFS lab. It was well attended - the feedback was that it was a little short - thats probably because in writing it I bacame very time-concious after the ASM/ACFS on Solaris extravaganza I ran last year which was almost too long for mortal man to finish in the 1 hour session. Enjoy. Table of Contents Exercise Z.1: ZFS Pools Exercise Z.2: ZFS File Systems Exercise Z.3: ZFS Compression Exercise Z.4: ZFS Deduplication Exercise Z.5: ZFS Encryption Exercise Z.6: Solaris 11 Shadow Migration Introduction This set of exercises is designed to briefly demonstrate new features in Solaris 11 ZFS file system: Deduplication, Encryption and Shadow Migration. Also included is the creation of zpools and zfs file systems - the basic building blocks of the technology, and also Compression which is the compliment of Deduplication. The exercises are just introductions - you are referred to the ZFS Adminstration Manual for further information. From Solaris 11 onward the online manual pages consist of zpool(1M) and zfs(1M) with further feature-specific information in zfs_allow(1M), zfs_encrypt(1M) and zfs_share(1M). The lab is easily carried out in a VirtualBox running Solaris 11 with 6 virtual 3 Gb disks to play with. Exercise Z.1: ZFS Pools Task: You have several disks to use for your new file system. Create a new zpool and a file system within it. Lab: You will check the status of existing zpools, create your own pool and expand it. Your Solaris 11 installation already has a root ZFS pool. It contains the root file system. Check this: root@solaris:~# zpool list NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT rpool 15.9G 6.62G 9.25G 41% 1.00x ONLINE - root@solaris:~# zpool status pool: rpool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c3t0d0s0 ONLINE 0 0 0 errors: No known data errors Note the disk device the root pool is on - c3t0d0s0 Now you will create your own ZFS pool.

Try creating a simple pool and observe the error message: root@solaris:~# zpool create mypool c3t2d0 c3t3d0 'mypool' successfully created, but with no redundancy; failure of one device will cause loss of the pool So destroy that pool and create a mirrored pool instead: root@solaris:~# zpool destroy mypool root@solaris:~# zpool create mypool mirror c3t2d0 c3t3d0 root@solaris:~# zpool status mypool pool: mypool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM mypool ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c3t2d0 ONLINE 0 0 0 c3t3d0 ONLINE 0 0 0 errors: No known data errors Back to topExercise Z.2: ZFS File Systems Task: You have to create file systems for later exercises. You can see that when a pool is created, a file system of the same name is created: root@solaris:~# zfs list NAME USED AVAIL REFER MOUNTPOINT mypool 86.5K 2.94G 31K /mypool Create your filesystems and mountpoints as follows: root@solaris:~# zfs create -o mountpoint=/data1 mypool/mydata1 The -o option sets the mount point and automatically creates the necessary directory. root@solaris:~# zfs list mypool/mydata1 NAME USED AVAIL REFER MOUNTPOINT mypool/mydata1 31K 2.94G 31K /data1 Back to top Exercise Z.3: ZFS Compression Task:Try out different forms of compression available in ZFS Lab:Create 2nd filesystem with compression, fill both file systems with the same data, observe results You can see from the zfs(1) manual page that there are several types of compression available to you, set with the property=value syntax: compression=on | off | lzjb | gzip | gzip-N | zle Controls the compression algorithm used for this dataset. The lzjb compression algorithm is optimized for performance while providing decent data compression. Setting compression to on uses the lzjb compression algorithm. The gzip compression algorithm uses the same compression as the gzip(1) command. You can specify the gzip level by using the value gzip-N where N is an integer from 1 (fastest) to 9 (best compression ratio). Currently, gzip is equivalent to gzip-6 (which is also the default for gzip(1)). Create a second filesystem with compression turned on. Note how you set and get your values separately: root@solaris:~# zfs create -o mountpoint=/data2 mypool/mydata2 root@solaris:~# zfs set compression=gzip-9 mypool/mydata2 root@solaris:~# zfs get compression mypool/mydata1 NAME PROPERTY VALUE SOURCE mypool/mydata1 compression off default root@solaris:~# zfs get compression mypool/mydata2 NAME PROPERTY VALUE SOURCE mypool/mydata2 compression gzip-9 local Now you can copy the contents of /usr/lib into both your normal and compressing filesystem and observe the results. Don't forget the dot or period (".") in the find(1) command below: root@solaris:~# cd /usr/lib root@solaris:/usr/lib# find . -print | cpio -pdv /data1 root@solaris:/usr/lib# find . -print | cpio -pdv /data2 The copy into the compressing file system takes longer - as it has to perform the compression but the results show the effect: root@solaris:/usr/lib# zfs list NAME USED AVAIL REFER MOUNTPOINT mypool 1.35G 1.59G 31K /mypool mypool/mydata1 1.01G 1.59G 1.01G /data1 mypool/mydata2 341M 1.59G 341M /data2 Note that the available space in the pool is shared amongst the file systems. This behavior can be modified using quotas and reservations which are not covered in this lab but are covered extensively in the ZFS Administrators Guide. Back to top Exercise Z.4: ZFS Deduplication The deduplication property is used to remove redundant data from a ZFS file system. With the property enabled duplicate data blocks are removed synchronously. The result is that only unique data is stored and common componenents are shared. Task:See how to implement deduplication and its effects Lab: You will create a ZFS file system with deduplication turned on and see if it reduces the amount of physical storage needed when we again fill it with a copy of /usr/lib. root@solaris:/usr/lib# zfs destroy mypool/mydata2 root@solaris:/usr/lib# zfs set dedup=on mypool/mydata1 root@solaris:/usr/lib# rm -rf /data1/* root@solaris:/usr/lib# mkdir /data1/2nd-copy root@solaris:/usr/lib# zfs list NAME USED AVAIL REFER MOUNTPOINT mypool 1.02M 2.94G 31K /mypool mypool/mydata1 43K 2.94G 43K /data1 root@solaris:/usr/lib# find . -print | cpio -pd /data1 2142768 blocks root@solaris:/usr/lib# zfs list NAME USED AVAIL REFER MOUNTPOINT mypool 1.02G 1.99G 31K /mypool mypool/mydata1 1.01G 1.99G 1.01G /data1 root@solaris:/usr/lib# find . -print | cpio -pd /data1/2nd-copy 2142768 blocks root@solaris:/usr/lib#zfs list NAME USED AVAIL REFER MOUNTPOINT mypool 1.99G 1.96G 31K /mypool mypool/mydata1 1.98G 1.96G 1.98G /data1 You could go on creating copies for quite a while...but you get the idea. Note that deduplication and compression can be combined: the compression acts on metadata. Deduplication works across file systems in a pool and there is a zpool-wide property dedupratio: root@solaris:/usr/lib# zpool get dedupratio mypool NAME PROPERTY VALUE SOURCE mypool dedupratio 4.30x - Deduplication can also be checked using "zpool list": root@solaris:/usr/lib# zpool list NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT mypool 2.98G 1001M 2.01G 32% 4.30x ONLINE - rpool 15.9G 6.66G 9.21G 41% 1.00x ONLINE - Before moving on to the next topic, destroy that dataset and free up some space: root@solaris:~# zfs destroy mypool/mydata1 Back to top Exercise Z.5: ZFS Encryption Task: Encrypt sensitive data. Lab: Explore basic ZFS encryption. This lab only covers the basics of ZFS Encryption. In particular it does not cover various aspects of key management. Please see the ZFS Adminastrion Manual and the zfs_encrypt(1M) manual page for more detail on this functionality. Back to top root@solaris:~# zfs create -o encryption=on mypool/data2 Enter passphrase for 'mypool/data2': ******** Enter again: ******** root@solaris:~# Creation of a descendent dataset shows that encryption is inherited from the parent: root@solaris:~# zfs create mypool/data2/data3 root@solaris:~# zfs get -r encryption,keysource,keystatus,checksum mypool/data2 NAME PROPERTY VALUE SOURCE mypool/data2 encryption on local mypool/data2 keysource passphrase,prompt local mypool/data2 keystatus available - mypool/data2 checksum sha256-mac local mypool/data2/data3 encryption on inherited from mypool/data2 mypool/data2/data3 keysource passphrase,prompt inherited from mypool/data2 mypool/data2/data3 keystatus available - mypool/data2/data3 checksum sha256-mac inherited from mypool/data2 You will find the online manual page zfs_encrypt(1M) contains examples. In particular, if time permits during this lab session you may wish to explore the changing of a key using "zfs key -c mypool/data2". Exercise Z.6: Shadow Migration Shadow Migration allows you to migrate data from an old file system to a new file system while simultaneously allowing access and modification to the new file system during the process. You can use Shadow Migration to migrate a local or remote UFS or ZFS file system to a local file system. Task: You wish to migrate data from one file system (UFS, ZFS, VxFS) to ZFS while mainaining access to it. Lab: Create the infrastructure for shadow migration and transfer one file system into another. First create the file system you want to migrate root@solaris:~# zpool create oldstuff c3t4d0 root@solaris:~# zfs create oldstuff/forgotten Then populate it with some files: root@solaris:~# cd /var/adm root@solaris:/var/adm# find . -print | cpio -pdv /oldstuff/forgotten You need the shadow-migration package installed: root@solaris:~# pkg install shadow-migration Packages to install: 1 Create boot environment: No Create backup boot environment: No Services to change: 1 DOWNLOAD PKGS FILES XFER (MB) Completed 1/1 14/14 0.2/0.2 PHASE ACTIONS Install Phase 39/39 PHASE ITEMS Package State Update Phase 1/1 Image State Update Phase 2/2 You then enable the shadowd service: root@solaris:~# svcadm enable shadowd root@solaris:~# svcs shadowd STATE STIME FMRI online 7:16:09 svc:/system/filesystem/shadowd:default Set the filesystem to be migrated to read-only root@solaris:~# zfs set readonly=on oldstuff/forgotten Create a new zfs file system with the shadow property set to the file system to be migrated: root@solaris:~# zfs create -o shadow=file:///oldstuff/forgotten mypool/remembered Use the shadowstat(1M) command to see the progress of the migration: root@solaris:~# shadowstat EST BYTES BYTES ELAPSED DATASET XFRD LEFT ERRORS TIME mypool/remembered 92.5M - - 00:00:59 mypool/remembered 99.1M 302M - 00:01:09 mypool/remembered 109M 260M - 00:01:19 mypool/remembered 133M 304M - 00:01:29 mypool/remembered 149M 339M - 00:01:39 mypool/remembered 156M 86.4M - 00:01:49 mypool/remembered 156M 8E 29 (completed) Note that if you had created /mypool/remembered as encrypted, this would be the preferred method of encrypting existing data. Similarly for compressing or deduplicating existing data. The procedure for migrating a file system over NFS is similar - see the ZFS Administration manual. That concludes this lab session.

• Oracle RDBMS Server 11gR2 Pre-Install RPM for Oracle Linux 6 has been released

  - by Lenz Grimmer

  Now that the certification of the Oracle Database 11g R2 with Oracle Linux 6 and the Unbreakable Enterprise Kernel has been announced, we are glad to announce the availability of oracle-rdbms-server-11gR2-preinstall, the Oracle RDBMS Server 11gR2 Pre-install RPM package (formerly known as oracle-validated). Designed specifically for Oracle Linux 6, this RPM aids in the installation of the Oracle Database. In order to install the Oracle Database 11g R2 on Oracle Linux 6, your system needs to meet a few prerequisites, as outlined in the Linux Installation Guides. Using the Oracle RDBMS Server 11gR2 Pre-install RPM, you can complete most of the pre-installation configuration tasks. which is now available from the Unbreakable Linux Network, or via the Oracle public yum repository. The pre-install package is available for x86_64 only. Specifically, the package: Causes the download and installation of various software packages and specific versions needed for database installation, with package dependencies resolved via yum Creates the user oracle and the groups oinstall and dba, which are the defaults used during database installation Modifies kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum number of file descriptors, and so on Sets hard and soft shell resource limits in /etc/security/limits.conf, such as the number of open files, the number of processes, and stack size to the minimum required based on the Oracle Database 11g Release 2 Server installation requirements Sets numa=off in the kernel boot parameters for x86_64 machines Please see the release announcement for further details and instructions. Also take a look at Ginny Henningsen's "How I Simplified Oracle Database Installation on Oracle Linux" article on the Oracle Technology Network for a general description on how to perform the installation of the Oracle Database on Oracle Linux. While the article refers to Oracle Linux 5 and the former "oracle-validated" package, the steps for Oracle Linux 6 are still very similar (we're looking into updating that article for Oracle Linux 6).

• Troubleshoot broken ZFS

  - by BBK

  I have one zpool called tank in RaidZ1 with 5x1TB SATA HDDs. I'm using Ubuntu Server 11.10 Oneric, kernel 3.0.0-15-server. Installed ZFS from ppa also I'm using zfs-auto-snapshot. The ZFS file system when zfs module loaded to the kernel hangs my computer. Before it I created few new file systems: zfs create -V 10G tank/iscsi1 zfs create -V 10G tank/iscsi2 zfs create -V 10G tank/iscsi3 I shared them through iSCSI by /dev/tank/iscsiX path. And my computer started to hanging sometimes when I used tank/iscsiX by iSCSI, do not know why exactly. I switched off iSCSI and started to remove this file systems: zfs destroy tank/iscsi3 I'm also using zfs-auto-snapshot so I had snapshots and without -r key my command not destroying the FS. So I issued next command: zfs destroy tank/iscsi3 -r The tank/iscsi3 FS was clean and contain nothing - it was destroyed without an issue. But tank/iscsi2 and tank/iscsi1 contained a lot of information. I tried zfs destroy tank/iscsi2 -r After some time my computer hang out. I rebooted computer. It didn't boot very fast, HDDs starts working like a crazy making a lot of noise, after 15 minutes HDDs stopped go crazy and OS booted at last. All seems to be ok - tank/iscsi2 was destroyed. After file systems at the tank was accessible, zpool status showed no corruption. I issued new command: zfs destroy tank/iscsi1 -r Situation was repeated - after some time my computer hang out. But this time ZFS seams not to healed itself. After computer switched on it started to work: loading scripts and kernel modules, after zfs starting to work it hanging my computer. I need to recover else ZFS file systems which lying in the same zpool. Few month ago I backup OS to flash drive. Booting from backed-up OS and import have the same results - OS starts hanging. How to recover my data at ZFS tank?

• no hdmi sound on Ubuntu 12.04 LTS

  - by bart

  i'm very new to ubuntu/linux. I installed Ubuntu 12.04 LTS on my vista laptop (nvidia gpu) in dual boot and with some help of google i'm almost ready to go. The only thing that i can't figure out is how to play sound trough my hdmi connected to my tv. Speakers of the laptop are ok, in te sound settings i can see -hdmi -digital -speaker outputs. The top 2 won't play sound so i googled around, found a bunch of things to try but the only thing succesfull so far was to erase all the drivers from the audio settings and they stayed gone. So finally i re-installed from scratch but still no sound trough hdmi. Re-installed 6times in the last 3 days now so the only thing left for me is reaching out for help/advice about this. How can i play sound on my tv connected with hdmi? I will be glad to give more info if needed cuz this is driving me crazy, thanks for your help in advance ! Bart.

• Workflow: Operate Zones

  - by Owen Allen

  The Operate Zones workflow is another of the workflow documents that we introduced recently. It follows naturally after the Deploy Oracle Solaris 11 Zones workflow that I talked about last week, so I thought I'd talk about it next. This workflow is less linear than the zone deployment workflow. It's built around this image: The left side shows you the prerequisites for zone operation: you have to deploy libraries and deploy either Oracle Solaris 10 or 11 zones - whichever type you want to manage using this workflow. Once you have the zones deployed, you can begin to operate them. If you want to associate resources with the global zone, the workflow directs you to the Exploring Your Server Pools how-to, which talks about adding global zones to server pools and associating libraries and network resources with them. Otherwise, it directs you to a set of how-tos about zone management: Managing the Configuration of a Zone, which explains how to add storage, edit zone attributes, and connect zones to networks; Lifecycle Management of Zones, which explains how to halt, shut down, boot, reboot, or delete a zone; and Migrating Zones, which explains how to move a zone to a new global zone in the same server pool. Finally, it directs you to the Update Oracle Solaris workflow when you want to update your zones, and to the Monitor and Manage Incidents workflow to learn more about monitoring your assets.

• How to start a task before networking?

  - by user1252434

  I've written an upstart task that modifies /etc/network/interfaces. (Actually a file sourced into it.) Which start on condition do I need to declare to let my task run before any networking jobs? I've tried start on starting networking, but that's apparently too late. When I log in after booting I can see that the changes were written, but obviously they are not used: the new config states a static IP, but the boot process waits for a non-existing DHCP server (old config) to time out. I've also tried start on starting network-interface INTERFACE=eth0, which didn't work either. IIRC there was an error in the log that the change couldn't be written. Background: I need a VM template that can be cloned and the clones configured through a script. Among other settings, I need to give them a static IP address to access them from the host. I use guestfish to write a config file to one of the virtual disks and let a script apply these settings to the system. I don't want that disk to contain an actual system settings file. I can't modify /etc directly, because that disk is shared (copy-on-write/diff) among the clones and guestfish apparently doesn't support that type of image. I could also let them use DHCP and setup a server that assigns IP by MAC, but I'm afraid of the complexity. I could also add just another virtual disk for configuration files, but if possible I'd prefer to store settings directly on the system disk image. Used software: Ubuntu Server 12.04, VirtualBox. The configuration modifier is a self written ruby script.

• Fix Icon Display Problems by Rebuilding the Windows 7 Thumbnail Cache

  - by The Geek

  Have you ever been browsing through photos or videos on your PC, and noticed that the thumbnails weren’t showing up properly? Sometimes they get corrupted, and you can quickly rebuild them to fix the problem. Just for some background, let’s walk through what we’re talking about. Normally, when you’re browsing around your files, you’ll see thumbnails for pictures and videos that you are viewing. These thumbnails are all generated, and stored in a cache to make browsing files faster. But sometimes… the cache gets corrupted, and we need to rebuild them. Here’s an example of what happens when it goes out of whack… Rebuilding the Windows 7 Thumbnail Cache All you have to do is open up Disk Cleanup through the start menu search box (just type in disk cleanup to find it) Just make sure that Thumbnails is checked, and then click OK to run through the cleaning process.

• Booting from USB on Mac Air (using setup_mac_usb_boot.sh)

  - by Mike O

  So, I've been working on this for hours and it's getting a little tiring. As some of you may know, installing Ubuntu on Macs is frequently an adventure, and I'm experiencing that right now. The part I'm hung up on at the moment is making a bootable USB. I would just use a CD, but my laptop is a MacBook Air (which doesn't have a CD drive), and I don't own an external CD drive. I initially attempted to use the command line method supplied by the Ubuntu documentation here: https://help.ubuntu.com/community/How%20to%20install%20Ubuntu%20on%20MacBook%20using%20USB%20Stick However, that wasn't even recognized by rEFIt even when I made a number of different modifications to the process, so I quickly decided to look elsewhere. I came across this guide: https://help.ubuntu.com/community/MacBookAir4-2#Basic_Installation_Instructions This ended up working to a large extent. If I choose the supplied grub from rEFIt, it will bring me to the Ubuntu grub, asking me to try it, install, or check the disk. And if I choose to boot Linux directly from rEFIt, it will bring me to the language selection menu. But when I make my selection from either of these menus it pauses for about ten seconds and then gives me a command line error message. It begins with kernel panic - not syncing timer doesn't work through interrupt, and then shows about eight file names. Does anyone here have any ideas as to what can be causing this? I also tried the script with both Ubuntu 11.10 (the current version when the script was written) and 12.04.

• How to Upload Really Large Files to SkyDrive, Dropbox, or Email

  - by Matthew Guay

  Do you need to upload a very large file to store online or email to a friend? Unfortunately, whether you’re emailing a file or using online storage sites like SkyDrive, there’s a limit on the size of files you can use. Here’s how to get around the limits. Skydrive only lets you add files up to 50 MB, and while the Dropbox desktop client lets you add really large files, the web interface has a 300 MB limit, so if you were on another PC and wanted to add giant files to your Dropbox, you’d need to split them. This same technique also works for any file sharing service—even if you were sending files through email. There’s two ways that you can get around the limits—first, by just compressing the files if you’re close to the limit, but the second and more interesting way is to split up the files into smaller chunks. Keep reading for how to do both.

  As far as I can tell, most games have some sort of "game state system" which switches between the different game states; these might be things like "Intro", "MainMenu", "CharacterSelect", "Loading", and "Game". On the one hand, it totally makes sense to separate these into a state system. After all, they are disparate and would otherwise need to be in a large switch statement, which is obviously messy; and they certainly are well represented by a state system. But at the same time, I look at the "Game" state and wonder if there's something wrong about this state system approach. Because it's like the elephant in the room; it's HUGE and obvious but nobody questions the game state system approach. It seems silly to me that "Game" is put on the same level as "Main Menu". Yet there isn't a way to break up the "Game" state. Is a game state system the best way to go? Is there some different, better technique to managing, well, the "game state"? Is it okay to have an intro state which draws a movie and listens for enter, and then a loading state which loops on the resource manager, and then the game state which does practically everything? Doesn't this seem sort of unbalanced to you, too? Am I missing something?
