Hi, I'm wondering if this issue still happened while using Precise(12.04) kernel. >From what I heard, this issue might result from that kernel didn't send out >the drm ready event. So, it's possible that this issue is fixed by the newer kernel.

Appears to be a race condition. LightDM attempts to start before /dev/nvidiactrl is created. As a workaround add "sleep 1 && service lightdm start" to /etc/rc.local to start the service. ### This workaround is insufficient. Some users have reported that their systems do not start after initial user setup. Deleting the contents of /var/run/dbus/* resolves the issue in these cases. ### ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: xorg 1:7.6+7ubuntu7 ProcVersionSignature: Ubuntu 3.0.0-12.20-generic 3.0.4 Uname: Linux 3.0.0-12-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 280.13 Wed Jul 27 16:53:56 PDT 2011 GCC version: gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) .tmp.unity.support.test.0: ApportVersion: 1.23-0ubuntu3 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,decor,regex,snap,animation,resize,place,vpswitch,mousepoll,workarounds,gnomecompat,compiztoolbox,move,grid,imgpng,wall,fade,expo,session,unitymtgrabhandles,ezoom,scale,unityshell] CompositorRunning: compiz Date: Thu Oct 13 11:05:18 2011 DistUpgraded: Fresh install DistroCodename: oneiric DistroVariant: ubuntu DkmsStatus: nvidia-current, 280.13, 3.0.0-12-generic, x86_64: installed ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GpuHangFrequency: Continuously GpuHangReproducibility: Yes, I can easily reproduce it GpuHangStarted: Immediately after installing this version of Ubuntu GraphicsCard: nVidia Corporation Device [10de:0e31] (rev a1) (prog-if 00 [VGA controller]) Subsystem: CLEVO/KAPOK Computer Device [1558:5102] InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) JockeyStatus: xorg:nvidia_current - NVIDIA accelerated graphics driver (Proprietary, Enabled, In use) xorg:nvidia_current_updates - NVIDIA accelerated graphics driver (post-release updates) (Proprietary, Disabled, Not in use) MachineType: System76, Inc.
