I tried install the nvdia driver for ubuntu 17.10, but it was a failure the display was totally black. So I purged the Nvidia drivers and returned back to generic display driver but unfortunately it was not completely reverted back, which causing the following issues
- Never resume back from suspend mode
- Display resolution gone back to 1280x800
- No brightness control
- No night mode
Gama error. etc... My display card is 02:00.0 VGA compatible controller [0300]: NVIDIA Corporation C79 [GeForce 9400M] [10de:0863] (rev b1) The xrandr gives the following error
