It's the KDE compatibility plugin that causes the crash (unless compiz is run as root).
** Summary changed: - compiz 0.9 crashes unless it runs as root + compiz 0.9 crashes when KDE compatibility plugin is enabled unless it runs as root ** Description changed: Binary package hint: compiz When I try to log into the Natty classic desktop (with effects turned on), it looks very much like compiz is repeatedly crashing. I see the desktop background for around a second, then some windows (without decorations) for a second, then the desktop, etc. The keyboard is unresponsive during this time except that I can get a tty console. This continues for 10-20 iterations and then X locks up completely (no mouse, and I can't get a tty console). If I log in to 'classic desktop with no effects' mode and then run compiz as root (sudo compiz), it runs fine. If I run compiz without root privileges, compiz crashes (see attached crash log). I can run compiz in another user profile without issues - it only crashes in my normal user profile, which is shared with Maverick, ie compiz 0.8. + The problem is that if I enable KDE compatibility, compiz crashes at + startup. This might be because I have dockbarx installed and it uses the + KDE compatibility plugin - compiz doesn't crash in unity with the KDE + compat plugin enabled. + + There are two issues here: the KDE plugin shouldn't crash compiz; but if + compiz does crash repeatedly during initialisation, it should stop + trying to run and Ubuntu should fallback to some safe mode. + + ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: compiz 1:0.9.4git20110322-0ubuntu5 ProcVersionSignature: Ubuntu 2.6.38-7.38-generic 2.6.38 Uname: Linux 2.6.38-7-generic x86_64 NonfreeKernelModules: nvidia .proc.driver.nvidia.gpus.0: Error: [Errno 21] Is a directory: '/proc/driver/nvidia/gpus/0' .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: - NVRM version: NVIDIA UNIX x86_64 Kernel Module 270.30 Fri Feb 25 14:34:55 PST 2011 - GCC version: gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-6ubuntu4) + NVRM version: NVIDIA UNIX x86_64 Kernel Module 270.30 Fri Feb 25 14:34:55 PST 2011 + GCC version: gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-6ubuntu4) Architecture: amd64 CheckboxSubmission: 1bd8e90541d49b96c13cbfcc9baf103b CheckboxSystem: d00f84de8a555815fa1c4660280da308 CompizPlugins: [core,bailer,detection,composite,opengl,decor,mousepoll,vpswitch,regex,animation,snap,expo,move,compiztoolbox,place,gnomecompat,wall,ezoom,workarounds,staticswitcher,resize,fade,scale,session,unityshell] CompositorRunning: None Date: Sat Mar 26 09:31:30 2011 DistUpgraded: Log time: 2011-03-20 09:19:31.967259 DistroCodename: natty DistroVariant: ubuntu DkmsStatus: - nvidia-current, 270.30, 2.6.38-7-generic, x86_64: installed - nvidia-current, 270.30, 2.6.38-generic, x86_64: installed - vboxhost, 4.0.4, 2.6.38-7-generic, x86_64: installed - vboxhost, 4.0.4, 2.6.38-generic, x86_64: installed + nvidia-current, 270.30, 2.6.38-7-generic, x86_64: installed + nvidia-current, 270.30, 2.6.38-generic, x86_64: installed + vboxhost, 4.0.4, 2.6.38-7-generic, x86_64: installed + vboxhost, 4.0.4, 2.6.38-generic, x86_64: installed GraphicsCard: - nVidia Corporation G84 [GeForce 8600M GT] [10de:0407] (rev a1) (prog-if 00 [VGA controller]) - Subsystem: Dell Device [1028:022e] + nVidia Corporation G84 [GeForce 8600M GT] [10de:0407] (rev a1) (prog-if 00 [VGA controller]) + Subsystem: Dell Device [1028:022e] InstallationMedia: Ubuntu 10.04 "Lucid Lynx" - Alpha amd64 (20100224.1) InstallationMedia_: Ubuntu 10.04 "Lucid Lynx" - Alpha amd64 (20100224.1) JockeyStatus: xorg:nvidia_current - NVIDIA accelerated graphics driver (Proprietary, Disabled, In use) MachineType: Dell Inc.
