I am stuck with a black screen when booting 14.04. I can log in via CLI but cannot start the GUI. I have tried the standard fixes to no avail. I have tried installing lightdm, and removing and changing permissions of .Xauthority but this made no difference.

/var/log/Xorg.0.log contains the following errors:

[   327.953] (EE) [drm] KMS not enabled
[   327.970] (EE) Screen 0 deleted because of no matching config section.
[   327.987] (EE) FBDEV(0): FBIOBLANK: Invalid argument
[   328.035] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)
[   328.263] (EE) FBDEV(0): FBIOBLANK: Invalid argument

  • Certainly looks like an Nvidia driver problem. Have you tried booting with nomodeset kernel option to check that it's this graphics card error that is source of the issue? If installing the proprietary driver, have you tried to remove the nvidia-glx and linux-restricted-modules packages then re-running proprietary installer ?

From what I understand this error shows that your Nvidia driver has a problem. Did you figure out that you have the driver or not ? You can check it by typing

sudo apt-get install nvidia-*

and see what results do you have. You can also reinstall xorg-xserver so it may solve but your problem.
