Ever since the installation of Ubuntu 12.10 on my laptop today it has been refusing to start Xorg when booting on occasions. Randomly it works but about 75% of the time it either gives me a black screen with login prompt or the fail safe mode, the latter being the most common.
Using CTRL+ALT+F1 to go to a terminal like screen, I managed to crack open the /var/log/Xorg.0.log file on the "faulty" boot process. Here are some lines which look interesting to me:
(EE) intel(0): [drm] Failed to open DRM device for pci:0000:00:02.0: No such file or directory (EE) intel(0): Failed to become DRM master. (II) UnloadModule: "intel" (EE) Screen(s) found, but none have a usable configuration. Fatal server error: no screens found
It is apparently loading the "vesa" driver package.
Specs of my laptop:
- CPU: Intel Core i5 2450M
- GPU: Intel HD Graphics 3000
- RAM: 8 GB DDR3
- OS: Windows 8 + Ubuntu 12.10 (fully updated)
Any ideas? Any suggestions are very welcome, even if they don't work as expected.
