Public bug reported:
I'm using a Lenovo Thinkpad W540 containing an internal intel and a
nvidia graphics card.
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GK106GLM [Quadro K2100M]
(rev a1)
The Nouveau driver works (without 3d acceleration), but as soon as i
switch to the proprietary nvidia-331 driver, the system gets stuck at
the load screen and the login screen never shows up. Only option at this
point is to switch to the console and remove the nvidia driver via sudo
apt-get --purge remove nvidia-331
/var/log/Xorg.0.log shows two errors with the nvidia driver in place
[10.075] (EE) [drm] KMS not enabled
[10.087] (EE) Failed to initialize GLX extension (Compatible NVIDIA X
driver not found)
