I got a traceback (already attached, gdmlog1), which suggested something related to pthreads, so I tried disabling hyperthreading and all but one core in BIOS. This reduced the frequency of crashing from about once per 10 minutes to once per 2 days. I don't know if it's specific to the intel driver, or if it is a more general issue. As far as steps for reproducing the issue... I'm not exactly sure. This is a description of a typical session: 1. Log in via gdm. I'm using sawfish, with a custom Xsession. 2. Start a few programs. I ran xchat, chrome, midori, a few instances of dillo, and a few instances if urxvt (client/server mode, not independent instances). 3. Trigger a few window redraws, by changing desktops or moving windows around. I triggered these actions via key shortcuts, generally a few times in a fraction of a second. Result: Once in a while, step 3 will cause an Xorg crash. The frequency increases quite a bit with SMP enabled (2 cores + HT, so 4 logical CPUs). 0x000000000043d7e5 in PlayReleasedEvents () at ../../dix/events.c:1188 in ../../dix/events.c #0 0x000000000043d7e5 in PlayReleasedEvents () at ../../dix/events.c:1188 prev = <value optimized out> qe = 0x30d15f0 dev = <value optimized out> pDev = <value optimized out> #1 ComputeFreezes () at ../../dix/events.c:1385 replayDev = <value optimized out> w = <value optimized out> grab = <value optimized out> dev = <value optimized out> #2 0x000000000043df1b in ProcAllowEvents (client=0x2f913e0) at ../../dix/events.c:1846 time = {months = 0, milliseconds = 1161414} mouse = 0x2cf4dc0 keybd = <value optimized out> stuff = 0x304b590 #3 0x000000000042e2a9 in Dispatch () at ../../dix/dispatch.c:431 clientReady = 0x2e77e40 result = <value optimized out> client = 0x2f913e0 nready = 0 icheck = 0x7f1410 start_tick = 120 #4 0x0000000000421a7e in main (argc=6, argv=<value optimized out>, envp=<value optimized out>) at ../../dix/main.c:287 i = <value optimized out> alwaysCheckForInput = {0, 1} ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: xorg 1:7.6+4ubuntu3 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Uname: Linux 2.6.38-8-generic x86_64 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None DRM.card0.DP.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.HDMI.A.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.LVDS.1: status: connected enabled: enabled dpms: On modes: 1280x800 1280x800 edid-base64: AP///////wAwrhFAAAAAAAATAQOAGhB46lzVk1xejiccUFQAAAABAQEBAQEBAQEBAQEBAQEB7hoAgFAgEDAQMBMABaMQAAAZ0BcAxlAgGTAwIDYABaMQAAAZAAAADwCBCjyBCjIWCQBMo0FUAAAA/gBMVE4xMjFBVDA3TDAyADg= DRM.card0.VGA.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: Date: Wed May 11 01:51:39 2011 DistUpgraded: Log time: 2011-05-08 22:00:44.661710 DistroCodename: natty DistroVariant: ubuntu EcryptfsInUse: Yes GraphicsCard: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:215a] InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101007) MachineType: LENOVO 3249CTO ProcEnviron: LANGUAGE=en_US:en PATH=(custom, user) LANG=C SHELL=/bin/zsh ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-2.6.38-8-generic root=UUID=067abbb3-2b82-460b-8e84-083cc85dfa86 ro quiet splash vt.handoff=7 Renderer: Unknown SourcePackage: xorg UpgradeStatus: Upgraded to natty on 2011-05-09 (1 days ago) dmi.bios.date: 12/17/2010 dmi.bios.vendor: LENOVO dmi.bios.version: 6QET62WW (1.32 ) dmi.board.name: 3249CTO dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr6QET62WW(1.32):bd12/17/2010:svnLENOVO:pn3249CTO:pvrThinkPadX201:rvnLENOVO:rn3249CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 3249CTO dmi.product.version: ThinkPad X201 dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.4+bzr20110415-0ubuntu2 version.ia32-libs: ia32-libs 20090808ubuntu13 version.libdrm2: libdrm2 2.4.23-1ubuntu6 version.libgl1-mesa-dri: libgl1-mesa-dri 7.10.2-0ubuntu2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 7.10.2-0ubuntu2 version.xserver-xorg: xserver-xorg 1:7.6+4ubuntu3 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.14.0-0ubuntu4 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.14.0-4ubuntu7.1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:0.0.16+git20110107+b795ca6e-0ubuntu7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/780961/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
