• Internal speakers do not work

  - by Nikcefo

  I have a new (from scratch, not update) installation of Ubuntu 12.10 on my notebook, Asus A3Ac (It is based on Intel Centrino - Pentium M with full duplex Intel HDA codec). In older versions of Debian-based systems Intel HDA audio didn't work correctly. Alsamixer display wrong outputs and inputs (more than notebook really have). In clean installations internal speakers were playing, but they didn't mute when headphones was plugged in. There was a solution (propably not the best but working) - edit as root /etc/modprobe.d/alsa-base.conf and add a line "options snd-hda-intel model=z71v position_fix=1". After restart it worked correctly (alsamixer displayed correct devices and internal speakers were muted after I plugged in headphones). It was also working in Ubuntu 12.04. In Ubuntu 12.10 I have another problem. The alsamixer in default (don't have to edit alsa-base.conf) display correct outputs and inputs but internal speakers don't working if the headphones isn't plugged in. I have to manually disable "Auto-Mut" option in alsamixer, then the internal spakers works (but of course they don't mute when the headphones are pluged in). Thanks for any idea how to fix it. I'm not sure if it is a bug or it's caused by a "specific hardware". Tomas

• How to make variable range of cells?

  - by Ertai

  In A column I have a set of numbers (over 1 000). I want to get average of ten of them (a1:a10) and wrtite into next column (B). Now I want to get next ten numbers and get average of them (a11:a20). And so on... How to get this if in C1 i would have number which is range (i.e 10 = a1:a10/a11:a20 ; i.e 25 a1:a25/a26:a50) of the cells? When I change C1 value I want to column B to update automaticaly? Is this possible?

• ATI Radeon Drivers works with which linux distribution and version? [closed]

  - by amit.codename13

  I have ATI Mobility Radeon HD 5850 graphics card. Almost every new linux distribution seems to have an issue with it, when i install the drivers. Working without utilizing the graphics card leaves me so unproductive. So i made a plan to use older versions of linux, any distribution suitable as a desktop distribution. The problems that i am facing are, 1) After installing drivers the system boots and hangs, 2) There are unusual lines over the screen 3) After upgrade system doesn't start properly(hangs the usual old way) The kind of answers i am looking for is, distribution X(the newer the version the better) doesn't have the above problem after installing drivers for ATI Mobility Radeon HD 5850 graphics card. UPDATE: The new drivers released by AMD seems to fix all the issues, although they are still beta

• Running commands on FreeBSD Live CD

  - by jmc

  I'm running FreeBSD 9.1-PRERELEASE on a vps running on XEN virtualization, I tried to update it to 9.1-RELEASE but mergemaster toasted my /etc/master.passwd and /etc/passwd so what i have now is a blank copies of the two files. What i did is use a mounted Live CD and mount my root partition to /mnt and manually re listed every entry to /mnt/etc/master.passwd and /mnt/etc/passwd from another freebsd server. I believe that everytime you edit master.passwd and passwd you have to run pwd_mkdb but this gives me "Read Only File" error. What I plan to do is enable PermitRootLogin and PermitEmptyPassword first so I can login as root first before I redo necessary changes again. But i have to run pwd_mkdb, so is there a way to run this command from Live CD?

• Advice on whether to use scripting, run time compile or something else

  - by Gaz83

  I work in the prodution area at my works and I design and create the software to run our automated test equipment. Everytime I get involved with a new machine I end up with a different and (hopefully) better design. Anyway I have come to the point where I feel I need to start standardization all the machines with the same program. I see a problem when it comes to applying updates as at the moment the test procedures are hard coded into the program at each station. I neeed to be able to update the core program without affecting the testing section. The way I see it that this will mean splitting the program into 2 sections. Main UI - This is the core that talks to everything on the machine such as cameras, sensors, printer etc and is a standalone application. Test Procedure - This is the steps that is executeted everytime the machine runs through a test. The main UI will load the test procedure and execute when ever a test is required. My question is what is the best approach to this in terms of having an application load a file and execute the code with in? Take into account that the code in the test procedure will need access to public methods on the UI/core system to communicate to sensors etc. I have heard about MS Roslyn and had a quick look, would this solve my issue?

• Can I make a business in teaching home users Ubuntu [on hold]

  - by Dorgaldir

  I was thinking about a way to bring Ubuntu to the bigger public, since it has great advantages for people in the lower income class that only use a PC for basic usage. They pay for a windows licence without actually needing windows because 95% of what they do is in a browser and the other 5% is typing a word document or making a simpel Excel sheet. So for these people something like Ubuntu is ideal, they can prolong the life of their old PC or laptop with Ubuntu and thus saving extra money. And as we all know, saving money is not only interesting for the lowest of income but for most of us. But when I talk to people they don't want to use Ubuntu because they know Windows and they don't know this, they'll complain about having to adapt to windows 8 but adapting to Ubuntu seems a bridge too far. But what if someone in the neighborhood gave simple Ubuntu courses. Teaching people about Ubuntu, stuff like: What is an OS What is Ubuntu How do I obtain Ubuntu How do I install Ubuntu How do I set up my email in Ubuntu How do I make a text document in Ubuntu How do I update my facebook wall in Ubuntu ... Simple basic PC usage, but within Ubuntu. But as much as I would like to work for free all day, I can't do this for free for people outside of my social circle. So I was wondering if it is possible to make a business and make money with giving Ubuntu courses, or are their steps to be taken before this is possible. However... Do I need an Ubuntu or Canonical license? Do I need to get a certificate? Do I have to make some kind of deal or contract with Canonical? Just to be clear this is all just an idea in my head at this point, I'm just gathering information. I'm not a teacher at a school, just a programmer that is thinking about options in life. Thanks in advance!

• I can't set the resolution to that recommended by my monitor

  - by F4r-20

  Firstly, I have looked here but didn't find what I needed. I have a Dell Optiplex 380 only using the on-board graphics (believe its the Intel G41 Express Chipset) but I can't seem to get the resolution right. The monitor I'm using (HP LE1901w) wants me to use 1440x900 but the only options I get are: 1600 x 1200 1366 x 768 1360 x 768 1280 x 1024 1280 x 960 1152 x 864 1024 x 768 800 x 600 So it will allow me to go higher or lower but not 1440x900. I've tried getting the driver from various different sources (Dell, Intel, Windows 7 Update) but still can't get that option. Does anybody know what else I can try?

• Can I set up samba so it automatically allows all the local usernames and passwords?

  - by dialer

  I have set up samba like this (this is the complete smb.conf): [global] log file = /var/log/samba/log log level = 2 security = user [homes] browsable = false read only = no valid users = %S I'd like to enable every user on server to access their home directories, but for some unknown reason only my 'administrator' account can do so. (I have done that with ftp before, but now smb is also needed). When I try to smbclient -L localhost -U [user], I get NT_STATUS_LOGON_FAILURE, except with the administrator (which is the user created during the ubuntu installation, not root). The samba log file says NT_STATUS_NO_SUCH_USER: [2012/04/04 20:26:02.081454, 2] smbd/reply.c:554(reply_special) netbios connect: name1=LOCALHOST 0x20 name2=DIALER-X 0x0 [2012/04/04 20:26:02.081733, 2] smbd/reply.c:565(reply_special) netbios connect: local=localhost remote=dialer-x, name type = 0 [2012/04/04 20:26:02.087200, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [public] - [public] FAILED with error NT_STATUS_NO_SUCH_USER I suspect that I have to manually create samba users, but the man pages state that If the client has passed a username/password pair and that username/password pair is validated by the UNIX system's password programs, the connection is made as that username. To me that sounds like as long as the provided username/password is a valid login on the server, it should work. Am I missing something totally obvious? I don't want / can't afford to manually update the samba users and passwords to match the server's. 11.10

• Oracle Secure Global Desktop (SGD) 5.1

  - by wcoekaer

  Last week, we released the latest update of Oracle Secure Global Desktop. Release 5.1 introduces a number of bug fixes and smaller changes but the most interesting one is definitely increased support for html5-based client access. In SGD 5.0 we added support for Apple iPads using Safari to connect to SGD and display your session right inside the browser. The traditional model for SGD is that you connect using a webbrowser to the webtop and applications that are displayed locally using a local client (tta). This client gets installed the first time you connect. So in the traditional model (which works very well...) you need a webbrowser, java and the tta client. With the addition of html5 support, there's no longer a need to install a local client, in fact, there is also no longer a need to have java installed. We currently support Chrome as a browser to enable html5 clients. This allows us to enable html5 on the android devices and also on desktops running Chrome (Windows, MacOS X, Linux). Connections will work transparently across proxy servers as well. So now you can run any SGD published app or desktop right from your webbrowser inside a browser window. This is very convenient and cool.

• Listing packages in a repositiory?

  - by noloader

  I'm working on Ubuntu 12.04 Server. I want to install OpenStack, so I enabled the Cloud Archive repo: sudo add-apt-repository cloud-archive:havana After the subsequent update and upgrade, I noticed python-crypto changed. python-crypto recently fixed a CVE, so I would like to ensure I'm using the patched version of python-crypto. I'd also like to compare the python-crypto in both Ubuntu and Cloud Archive. How does one list the package information for both Ubuntu::python-crypto and CloudArchive::python-crypto? (And sorry I could not tag this with apt-cache. Its not available in the list of tags). Thanks in advance

• Create shortcut key to insert new row using Excel 2010

  - by Dave Jarvis

  Tried to create a macro in Excel to insert a row: Sub InsertRow() ' ' InsertRow Macro ' ' Keyboard Shortcut: Ctrl+Shift+I ' Selection.EntireRow.Insert End Sub However, this does not insert a new row without first manually selecting a row. Every solution I've found requires that a row be highlighted before inserting a new row. See also: http://www.shortcutworld.com/en/win/Excel_2010.html How would you create a shortcut key (e.g., Ctrl+Shift+J) to highlight the current row and insert a new row? Thank you! Update Looks like Shift+Space highlights the current row.

• Fully secured gateway web sites

  - by SeaShore

  Hello, Are there any web sites that serve as gateways for fully encrypted communication? I mean sites with which I can open a secured session, and then to exchange through them with other sites in a secure way both URLs and content? Thanks in advance. UPDATE Sorry for not being clear. I was wondering if there was a way to access any site over the Internet (http or https) without letting any Intranet-proxy read the requested URL or the received content. My question is whether such a site exists, e.g.: I am connected to that site via https, I send it a URL in a secured way, the site gets the content from the target site (possibly in a non-secured way) and returns to me the requested content in a secured way.

• Kubuntu guest on Windows 8.1 Hyper-V won't shut down completely

  - by DarkMoon

  I've got a Windows 8.1 Professional laptop with Hyper-V installed, and a Kubuntu 14.04 Desktop VM. When I shutdown the Kubuntu VM, most of the time it gets to the logo screen, and just sits there. It's not frozen, because I can see the glow around the logo brighten and fade. I have installed the four Hyper-V modules, and lsmod shows them all running fine before the shutdown. Also, once it's stuck on the logo screen, if I send a CTL-ALT-DEL to the VM, it restarts immediately. Does anyone have any idea where I'd begin troubleshooting this? UPDATE: I've disabled the startup and shutdown screens, and now can see this output when it's stopped. Hopefully this sheds more light on the problem.

• How do I scale EC2 and push out code / data to my instances?

  - by chris

  Unfortunately I only have a limited knowledge of server architecture, I come from a development background. I am looking to ensure my new app can scale properly using EC2. I currently have a T1.micro for development running Windows with SQL server 2008. The system allows students to come to our site to search for a mentor, update their profile with pictures and employment history etc. Roughly the same sort of work as a LinkedIn profile. I need this to be able to scale very quickly without wasted resources. I understand the following is important. Separation of data, application etc. I will achieve this I think by hosting images using S3, Database instance via RDS and upgrade the EC2 instance. My main question is: How do I push data / code out to multiple ec2 / RDS instances seamlessly?

• Yum through http proxy

  - by eodchop

  I have several Fedora 13 servers that have to connect through an http proxy for yum updates. All port 80 traffic has to be routed through this proxy. I have setup the proxy server in the network settings GUI. I can browse the internet just fine. I have also setup my proxy information in /etc/yum.conf as follows: proxy=http:proxy.largecorp.corp/accelerated_pac_base.pac proxy_user=user proxy_password=password I then added the export HTTP_PROXY="http:proxy.largecorp.corp/accelerated_pac_base.pac" to /etc/bashrc and sourced the file. When i run yum update: Loaded plugins:presto, refresh-packagekit Error: Cannot retrieve repository metadata (repomd.xml) fro repository: fedora. Please verify its path and try again. All of the repo urls are the defaults, as this is a fresh install.

• Installing nVidia drivers for Quadro FX 880M on 10.10 caused shutdown/startup issues.

  - by Chantz

  So I was facing weird graphics drivers issues due to the default nouveau drivers that came installed with Ubuntu 10.10 hence I installed the latest nVidia graphics drivers & I the weird graphics issues stopped happening. So far so good, but when I tried to shut down the laptop it got stuck at the window with text 15, shutting down... modem-manager: Caught signal 15, shutting down... init: Disconnected from system us init: dbus main process (1107) killed by TERM signal And this happens .everytime.without.fail. I tried updating the kernel and any/all drivers through update manager but it stil happens. Not only this even the startup screen is totally screwed up. It just displays Ubuntu 10.10 in text with 3 dots. But that is acceptable. To power cycle down the laptop each and everytime for shutdown is not cool. Same goes for when I try to restart. Interesting thing is if I try to shutdown the laptop when I am on the login screen it does so without any problems. I googled & many people seem to face the same issue but I couldn't find any silver bullet hoping to find one here.

The following information may help to resolve the situation: The following packages have unmet dependencies: filezilla: Depends: libatk1.0-0 (>= 1.29.3) but 1.28.0-0ubuntu1 is to be installed Do you have any idea what is happening?

• Why am I seeing so many instantiable classes without state?

  - by futlib

  I'm seeing a lot of instantiable classes in the C++ and Java world that don't have any state. I really can't figure out why people do that, they could just use a namespace with free functions in C++, or a class with a private constructor and only static methods in Java. The only benefit I can think of is that you don't have to change most of your code if you later decide that you want a different implementation in certain situations. But isn't that a case of premature design? It could be turned into a class later, when/if it becomes appropriate. Am I getting this wrong? Is it not OOP if I don't put everything into objects (i.e. instantiated classes)? Then why are there so many utility namespaces and classes in the standard libraries of C++ and Java? Update: I've certainly seen a lot examples of this in my previous jobs, but I'm struggling to find open source examples, so maybe it's not that common after all. Still, I'm wondering why people do it, and how common it is.

• Is there Linux Live USB that works with Snow Leopard macbook pro from 2010 april

  - by rofrol

  Hello, I was searching for a long time a Linux Live USB that I can boot my macbook pro from. Is there such distro so I can install it on Snow Leopard or Windows 7? UPDATE I've found this: "isohybrid" CD images (..) are special in that as well as the normal CD-based ISO9660 filesystem they also contain a valid-looking DOS-style partition table. Thus, if you simply copy one of these images raw to a USB stick a normal PC BIOS will boot the image directly. (...) Finally: I'd like to add support into xorriso for creating the nasty HFS hybrid images that are needed for booting Macs. The code that does this in cdrkit is probably some of the worst that I've ever worked with, and I'd like to get away from it. If only Apple hadn't stupidly built their proprietary platform around this shit and had used open standards instead Source

• How to tell rsync not to touch the destination directory permissions?

  - by Sorin Sbarnea

  I am using rsync to sync a directory from a machine to another but I encountered the following problem: the destination directory permissions are altered. rsync -ahv defaults/ root@hostname:~/ The problem is that in this case the permissions and ownership of the defaults forlder will be assigned to the destination folder. I do want to keep the permissions for the files and subdirectories but not for the source directory itself. Also, I do not want to remove any existing files from the destination (but to update them if needed), but I think that current settings are already ok regarding this. How can I do this?
