Some tips: * Report X.org bugs via the command: `ubuntu-bug xorg` * Test against the latest development Ubuntu. http://cdimage.ubuntu.com/daily-live/ Bugs marked as affecting the development version tend to get priority attention. * The `xdiagnose` utility has functionality for enabling debugging and analyzing a few common X problems. * Tag your bugs with the Ubuntu versions you have reproduced the issue in. * See https://wiki.ubuntu.com/X/Reporting for tips on writing good bug reports. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => Expired -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/980058 Title: Sometimes see vertical bands, artifacts across screen after boot Status in The Plymouth splash screen: New Status in “xserver-xorg-video-intel” package in Ubuntu: Expired Bug description: Since updating from 12.04 Beta 1 to 12.04 (Final) (I went from 11.10 to 12.04 Beta 1 before that via a clean install), while booting, GRUB is displayed fine, and Ubuntu begins to boot fine. It's only when Plymouth is displayed (which happens fairly late into boot for me) that I start to experience problems. Most of the time, Plymouth is shown fine, and everything is great. However, occasionally Plymouth is shown garbled, there's little blobs of colour (Sorry I can't provide much information because Plymouth is only shown for a little while during my boot). Then I see vertical bands of colour, it kind of looks like my display has been stretched vertically and the whole display is 1px tall. (I have posted some videos showing the behaviour below). I can log in, log out, switch to TTY's - do whatever, but the screen still has vertical bands on it. Moving the mouse causes the bands to change/update. Switching to any TTY shows a blinking vertical line, which moves along as I type commands, but it's impossible to see them (you can just see the blinking cursor) I can SSH into the computer and collect any logs if they are needed. I then force shut-down the laptop and restart and everything works fine. The only kernel command I have added is acpi_backlight=vendor (to be able to set the backlight brightness) lsb_release -rd =========== Description: Ubuntu 12.04 LTS Release: 12.04 apt-cache policy xorg and apt-cache policy xserver-xorg-video-intel ========================================================================== xorg: Installed: 1:7.6+12ubuntu1 Candidate: 1:7.6+12ubuntu1 Version table: *** 1:7.6+12ubuntu1 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status xserver-xorg-video-intel: Installed: 2:2.17.0-1ubuntu4 Candidate: 2:2.17.0-1ubuntu4 Version table: *** 2:2.17.0-1ubuntu4 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status Below here is information from the original bug report (Before I upgraded from 12.04 Beta 1 to 12.04 (Final)). ========================= ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+12ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-23.36-generic 3.2.14 Uname: Linux 3.2.0-23-generic x86_64 NonfreeKernelModules: wl .tmp.unity.support.test.0: ApportVersion: 2.0.1-0ubuntu1 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,unitymtgrabhandles,workarounds,scale,expo,ezoom,unityshell] CompositorRunning: None Date: Thu Apr 12 17:15:47 2012 DistUpgraded: Fresh install DistroCodename: precise DistroVariant: ubuntu DkmsStatus: bcmwl, 5.100.82.38+bdcom, 3.2.0-17-generic, x86_64: installed bcmwl, 5.100.82.38+bdcom, 3.2.0-21-generic, x86_64: installed bcmwl, 5.100.82.38+bdcom, 3.2.0-22-generic, x86_64: installed bcmwl, 5.100.82.38+bdcom, 3.2.0-23-generic, x86_64: installed ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device [1025:0504] InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Beta amd64 (20120301) Lsusb: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp.
