apport information ** Tags added: apport-collected
** Description changed: The lower part of the screen gets scrambled / distorted sometimes. This happens very randomly, but not very often. This disruption just disappears either after a few seconds or always, when the mouse is moved or any key pressed. Everything is immediately back to normal then. The last time it occured was today, just a few seconds after login, while gnome-terminal and firefox open. This is a Lenovo G550 Laptop. Lucid 10.04 clean installed in April. The problem occures from that time on until now. I tried newer kernel.org kernels and the situation does not change. It seems to be a X.org or Gnome problem. I was able to take a photo with my phone a while back: http://web.student.tuwien.ac.at/~e0525417/screen.jpg part of "lspci": 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) I could not find useful information in /sys/kernel/debug/dri/0/ I have Compiz enabled. + --- + Architecture: i386 + DistroRelease: Ubuntu 10.04 + EcryptfsInUse: Yes + InstallationMedia: Ubuntu 10.04 "Lucid Lynx" - Release Candidate i386 (20100419.1) + MachineType: LENOVO 2958 + NonfreeKernelModules: wl + Package: xserver-xorg-video-intel 2:2.9.1-3ubuntu5 + PackageArchitecture: i386 + ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.32-25-generic root=UUID=2da4676f-b2ae-44f4-883d-c2057d6e2090 ro + ProcEnviron: + LANG=de_AT.utf8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.32-25.44-generic 2.6.32.21+drm33.7 + Tags: lucid lucid + Uname: Linux 2.6.32-25-generic i686 + UserGroups: adm admin cdrom dialout disk lpadmin plugdev sambashare + dmi.bios.date: 09/18/2009 + dmi.bios.vendor: LENOVO + dmi.bios.version: 18CN37WW(V2.10) + dmi.board.name: NITU1 + dmi.board.vendor: LENOVO + dmi.board.version: REFERENCE + dmi.chassis.asset.tag: No Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: No Enclosure + dmi.chassis.version: N/A + dmi.modalias: dmi:bvnLENOVO:bvr18CN37WW(V2.10):bd09/18/2009:svnLENOVO:pn2958:pvrLenovoG550:rvnLENOVO:rnNITU1:rvrREFERENCE:cvnNoEnclosure:ct10:cvrN/A: + dmi.product.name: 2958 + dmi.product.version: Lenovo G550 + dmi.sys.vendor: LENOVO + glxinfo: Error: [Errno 2] No such file or directory + system: + distro: Ubuntu + codename: lucid + architecture: i686 + kernel: 2.6.32-25-generic ** Attachment added: "BootDmesg.txt" https://bugs.edge.launchpad.net/bugs/658705/+attachment/1696243/+files/BootDmesg.txt -- Lower part of the screen gets disrupted occasionally https://bugs.launchpad.net/bugs/658705 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
