@Jaime: for some reason your user session fails to authenticate: "Session: Failed during authentication"
I don't know why this happens and I'm not familiar with Xubuntu. Also I don't know what you mean by "blue screen" after grub. The boot splash will change if you use nvidia (plymouth text mode) instead of nouveau (plymouth graphics mode). One thing is certain: you're not experiencing the problem this bug report is about. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/873495 Title: LightDM fails to start after nvidia-current or nvidia-current-updates are installed (upstart job issue) Status in Light Display Manager: New Status in “lightdm” package in Ubuntu: Triaged Status in “lightdm” source package in Precise: Triaged Bug description: Occurs reliably on fast Sandy Bridge hardware with a fast GPU - GTX 485M, GTX 560M or GTX 580M. 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.
