I have netbook with following hardware config:

  1. Ubuntu 14.04
  2. Intel i5 4th gen
  3. NVIDIA 820m graphics card using Nouveau display driver v346

if I run sudo service lightdm restart I get black screen, instead of login screen, why is that?


  1. I dont get such problem if I am using Intel display driver instead of NVIDIA display driver
  2. I tried using different versions of NVIDIA drivers but got same problem on all

Update: link to my /var/log/Xorg.0.log here

  • most likely a driver issue: what does /var/log/Xorg.0.log tell you? – umläute Mar 30 '15 at 8:05
