• VLC Ati Radeon 6870 Ubuntu 12.04 image skewed flicker

  - by Aaron

  I'm running Ubuntu 12.04 with ATI Radeon 6870 connected to my 40' Sharp TV. The video image is slightly jigged, like breaking a bit and slightly delayed. It just isn't smooth. The computer is very fast, like i7 with 12gb ram. I tried to run the same video with my mac laptop and on the tv with the same connection cable and it was running smoothly. i tried changing the video output in VLC to x11, increase caching, h264 skip loop filter to all, increase monitor refresh rate although it's already at 60 and it's an LCD tv. this is my xorg.conf : Section "ServerLayout" Identifier "amdcccle Layout" Screen 0 "amdcccle-Screen[3]-0" 0 0 EndSection Section "Module" Load "glx" EndSection Section "Monitor" Identifier "0-DFP9" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" Option "PreferredMode" "1920x1080" EndSection Section "Monitor" Identifier "0-DFP10" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1280x1024" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Device" Identifier "amdcccle-Device[3]-0" Driver "fglrx" Option "Monitor-DFP9" "0-DFP9" BusID "PCI:3:0:0" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Screen" Identifier "amdcccle-Screen[3]-0" Device "amdcccle-Device[3]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

• WSS_Content contains?

  - by Mike

  WSS 3.0:Windows2003 I have a content database that keeps growing for the name of simply, "WSS_Content" This database is aside from all the other content databases that are linked to an web application, but located in the same directory. I count 5 CONTENT databases on this directory, but only 4 web applications (excluding the centraladmin). Trouble is it keeps growing in size and I need to know what it is and why its growing. Is this a default database of some kind? Where and why would it grow? I recently found, through Central Administration, that one of my sites has a content database name of "WSS_Content_(random numbers and letters)" whereas, the other content databases would have a name like "WSS_Content_(WebApplicationName)" What gives?

• Setting affinity on windows server 2003

  - by Samuel

  I have a program that by default only runs on one CPU. I have tried using the start /affinity x notepad.exe batch command but i can't get it to run my program. it changes the title of the command line window but doesn't execute the program. this start command does work for notepad so it might just be a problem with the software. I have set the affinity manually via task manager so i know it works. I am not the programmer of this software so changing that is not an option.

• Kill xserver from command line (init 3/5 does not work)

  - by John Smith

  Hi, I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

• How to switch to a generic kernel in a headless Ubuntu Server 12.04?

  - by chmike

  I just got a dedicated server with Ubuntu 12.04 installed with a custom compiled kernel. Since I would like to install VirtualBox and this custom kernel doesn't support dynamic module loading (for security) I need to change the kernel. I'm running some Ubuntu servers for years but never palyed with grub and a headless computer. When the command update-grub is run it shows the different kernel it finds. Here is what I see Generating grub.cfg ... Found linux image: /boot/bzImage-3.2.13-xxxx-grs-ipv6-64 Found linux image: /boot/vmlinuz-3.2.0-34-generic Found initrd image: /boot/initrd.img-3.2.0-34-generic No volume groups found done The first one is the active one as seen with uname -r. To me it looks like the second kernel is the one I should use. But I don't know how to configure grub2 to use it. The computer is also configured with a software RAID using mdadm I guess. Never used that before. I don't know if playing with the grub of changing kernel could brake this. What must I do to set the generic kernel as the default one so that I can get VirtualBox running.

• How do install Ubuntu from a USB stick?

  - by Sophia

  When I go to the boot menu on my computer and select USB stick, the screen goes black and there comes a flickering underline. Like I could write something. But I can't. Whatever I push, nothing happens. Except the PrintScrn/SysRq button. When I push it, mu computer beeps. I get no choose menu. Nothing. I found out the usb stick is in msdos format. So what format should I use and how can I format it? I am not a computer geek who knows everything. I'm just a beginner. And only 16 years old. I've got a new problem. The screen isn't black anymore. Now there comes an error message: SYSLINUX 4.04 CHS 20110518 Copyright (C) 1994-2011 H.Peter Anvin et al ERROR:No configurationfile found No DEFAULT or UI configuration directive found! boot: And when I write something: boot:example Could not find kernel image:example boot: Why does this fail all the time? ps. I'm using Ubuntu Oneiric 11.10.

• Drupal on IIS 7 (PHP FastCGI) produces blank every 1 hr

  - by Morron

  Hi, I have Drupal running on IIS 7 with PHP Fast CGI installed. The FastCGI setting: http://img709.imageshack.us/img709/1748/fastcgisetting.jpg hxxp://img404.imageshack.us/img404/5837/fastcgisetting2.jpg I have Drupal running on isolated AppPool with default setting when I created the AppPool: hxxp://img716.imageshack.us/img716/5444/fastcgisetting3.jpg The problem is that after 1 hr or so If I browse to hxxp://localhost , there's nothing but only the blank page until IIS 7 is restarted. I think this has to do with PHP Process Recycling Behavior or other things that I'm not sure about. Can you show what's the cause of the problem?

• Linux - How to run Firefox with AT command

  - by conualfy

  I try to run a specified command on a desired time. I found at for this, and it seems to work fine if I run: echo "ls -al / > /home/florin/test.txt" | at 4:21am But I want to run a different thing: /usr/bin/firefox -new-tab http://google.ro I tried adapting the first line with my action (running it in terminal opens a new Firefox tab with http://google.ro, so the command is correct), but with at, it does not work: echo "firefox -new-tab http://google.ro" | at 4:23am The task seems to be scheduled, but it does not run. When running the previous line I get the default reply from at: warning: commands will be executed using /bin/sh Should my Firefox command be differently run in sh? Is there a way to do my action with at, or some other way? Thanks a lot!

• How create partitions with custom layout in VM on Xen Server?

  - by Valter Silva

  We use XenServer with RAID 0, as one disk only (I wonder if this is a good approach, if not what would be ?), then we install Xen. After that we put the centOS 6.4 x64 DVD in the server and try to install it. But when it should came the option to create a custom layout of the partitions, it don't. So when we choose the 'use entire disk', the OS start to be installed, and then create the default layout. With /home bigger than / which we don't want to do that. I wonder if this is a problem with : raid or xenserver or xenclient or centos ?

• How to determine if a CentOS system is Raid-1?

  - by Tedd Johnson

  I've tried searching for this answer, but haven't found anything elegant. I have numerous servers in a colo that is in another state. I need to find a way to check that the servers have RAID-1 on them, so that I can determine if they were setup correctly by my colo. df -h shows: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 442G 1.5G 418G 1% / /dev/sda1 99M 19M 75M 20% /boot tmpfs 4.0G 0 4.0G 0% /dev/shm however as CentOS uses LVM by default, this doesn't indicate if a RAID-1 is present. it is supposed to be a software raid, so I'm pretty sure there should be a way to check. Thanks

• Windows Server 2003/Exchange 2007: How to setup public domain mail.foo.com to route to internal exch

  - by ryan.keeter

  Good day, I have an internal Exchange Server 2007 and a Windows Server 2003 domain. At this point in time I have an external DNS setup (DynDNS 29.95 service) to resolve foo.com to my singular public IP address then it gets routed to external facing site. I would like to know how to setup POP on mail.foo.com and SMTP on smtp.foo.com, and more importantly, what needs to be setup in Exchange server to allow for this to happen. My end state is to send email through smtp.foo.com and receive mail on mail.foo.com. As of now, when I create a user within Exchange the default email address is [email protected], and I would like it to be [email protected]. Thank you and I appreciate the help as I am a .NET developer trying to do sys admin work, and it is MUCH harder than I have ever imagined, my hat is off to all sys admins and IT pros.

• What's your most controversial programming opinion?

  - by Jon Skeet

  This is definitely subjective, but I'd like to try to avoid it becoming argumentative. I think it could be an interesting question if people treat it appropriately. The idea for this question came from the comment thread from my answer to the "What are five things you hate about your favorite language?" question. I contended that classes in C# should be sealed by default - I won't put my reasoning in the question, but I might write a fuller explanation as an answer to this question. I was surprised at the heat of the discussion in the comments (25 comments currently). So, what contentious opinions do you hold? I'd rather avoid the kind of thing which ends up being pretty religious with relatively little basis (e.g. brace placing) but examples might include things like "unit testing isn't actually terribly helpful" or "public fields are okay really". The important thing (to me, anyway) is that you've got reasons behind your opinions. Please present your opinion and reasoning - I would encourage people to vote for opinions which are well-argued and interesting, whether or not you happen to agree with them.

• CyanogenMod Updates; Rolls out Android 2.3 to the Less Fortunate

  - by ETC

  If you’re one of the less fortunate (namely those forgotten by their carrier when it comes to phone OS upgrade time) you’ve got a friend in Cyanogen. They’ve rolled out a new Release Candidate update that includes Android 2.3 and a host of performance tweaks. First thing to note is that this is an RC and if you upgrade from CyanogenMod 6 to CyanogenMod 7 RC you’ll be trading a little bit of stability and a few features that haven’t made the jump from 6 to 7 in return for the newest features of Android 2.3. If you’re not comfortable with that wait for CyanogenMod 7 to update to a final release. For the intrepid, hit up the link below to read more and grab a copy. CyanogenMod-7 Release Candidates!

• Which window manager do you use?

  - by Stephan202

  Combining "What is your default web browser?" and "What are the differences between Linux Window Managers", I ask you: which window manager do you use, and why? Myself I prefer a minimal window manager on the one hand (in the past I used Fluxbox), but on the other hand wish to go with the main stream, to ease finding (Googling) solutions in case of problems. Hence I stick with Gnome as it is shipped with Ubuntu. Why do you use the window manager which you use? I understand some reasons may be subjective, but please try to cite technical reasons where possible.

• How to configure auto-logon in Active Directory

  - by Jonas Stensved

  I need to improve our account management (using Active Directory) for a customer support site with 50+ computers. The default "AD"-way is to give each user their own account. This adds up with a lot of administration with adding/disabling/enabling user accounts. To avoid this supervisors have started to use shared "general" accounts like domain\callcenter2 etc and I don't like the idea of everyone knowing and sharing accounts and passwords. Our ideal solution would be to create a group with computers which requires no login by the user. I.e. the users just have to start the computer. Should I configure auto-logon with a single user account like domain\agentAccount? Is there anything else to consider if I use the same account for all users? How do I configure the actual auto-logon with a GPO on the group? Is there a "Microsoft way" without 3rd party plugins? Or is there a better solution?

• Error accessing other groups files in apache

  - by Shashank Jain

  I am using Cloud9 IDE on my server, which creates files with default permission 640. As a result when I try to open those file via HTTP, apache shows permission denied error. When IDE is running as root user, files created belong to root:root. Also, when I see as what user is apache running, all its processes are shown to be running as root user. I cannot understand why still it cannot access files. I know if I add apache's user to group of file owner, it will work. But, I don't know which user to add. PS: I don't want to change permission of each file I create. I want less troubling solution.

• Signed and unsigned, and how bit extension works

  - by hatorade

  unsigned short s; s = 0xffff; int i = s; How does the extension work here? 2 larger order bytes are added, but I'm confused whether 1's or 0's are extended there. This is probably platform dependent so let's focus on what Unix does. Would the two bigger order bytes of the int be filled with 1's or 0's, and why? Basically, does the computer know that s is unsigned, and correctly assign 0's to the higher order bits of the int? So i is now 0x0000ffff? Or since ints are default signed in unix does it take the signed bit from s (a 1) and copy that to the higher order bytes?

• How can I setup a group writeable directory?

  - by meder

  $ whoami meder $ cd /var/www $ sudo mkdir html $ sudo groupadd web $ sudo usermod -a -G web meder $ sudo usermod -a -G web medertest $ sudo chown meder:web html $ sudo chmod -R g+rwx html The problem is, anytime I create a new file in /var/www/html even though the group is set to web, it is only writeable by the original user. I was given the advice of setting the umask to be 002 because the default is what causes the problems. But I would have to do this for all users in that group, and as far as I know it would be tedious having all of them modify ~/.bashrc to have umask 002. Even if I can do it myself with a shell command for all of those users, it still seems too tedious. Can anyone offer any advice on having a group writeable directory?

• Why does my screen dim on a desktop installation of Windows 7?

  - by Robert Cartaino

  Periodically, while using my Windows 7 Pro desktop installation, the screen suddenly dims. The brightness is about 75% normal (estimate). It's as if I am in a power-saving mode on a laptop running on batteries. But this is a full desktop installation. I know it is not a hardware glitch or monitor adjustment issue because the Windows cursor is still bright white while everything else goes dim. The Control Panel Power Options have not been changed. They are set to "Balanced [active]" and I have tried restoring the default settings. Flipping through the power and display settings, everything looks "normal." There is no screen saver or power-off-after settings apparent. Rebooting the system resets everything to full brightness but I can't find a way to restore it in Windows or to keep it from happening in the first place. Suggestions?
