I installed nvidia proprietary driver (331.38 on ubuntu 14.04 by sudo apt-get install nvidia-331) and now the Ubuntu load screen is with a bad resolution (640x480). I followed some recommendations from previous questions but I can not increase the resolution. I would like to return to 1920x1080 resolution.

  • just remove xorg.conf file by running sudo rm /etc/X11/xorg.conf – Avinash Raj Apr 18 '14 at 17:46

  • try nvidia-current instead of nvidia-331 – s3lph Apr 18 '14 at 22:10
  • Haven't seen this anywhere else, so I'm not sure if it always works. But switching from DVI - VGA --> Display to HDMI --> Display fixed this problem for me. – 0-60FPS Jul 13 '17 at 01:20
  • I had to add a line Option "UseEDID" "false" to the Section "Screen". This prevented the NVIDIA driver to query the supported modes and still somehow decide that the optimal resolution for the display is not optimal at all. Hope it helps you and others – asgs Nov 09 '17 at 16:54

I had this problem a few days ago, removing the xorg.conf created by Nvidia seems to fix the problem. Execute the commands below after pressing CTRL+ALT+F1 on GDM screen or within GNOME.

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
sudo touch /etc/X11/xorg.conf

I installed the nvidia-396 driver through the .deb file for CUDA Toolkit 9.2, downloaded from here. Running Ubuntu 18.04.

I somehow ended up with a complete blank xorg.conf and was also stuck at 640x480 resolution.

I solved by running sudo nvidia-xconfig. This generated a populated xorg.conf which overrode the blank one. Resolution was fixed after a reboot.

When I did that on my xps 15 (optimus gt 540) the screen was blank, So I removed the drivers (sudo apt-get remove --purge nvidia-*) and then reinstalled ubuntu-desktop, then the resolution was fine.

    I need the nvidia drivers to use Steam and another things. The resolution problem occurs only in the load screen (Ubuntu .... screen), after load the resolution of all becomes normal (but the load screen is ugly). – Márcio Apr 18 '14 at 21:28
  • This is not a solution to fix the actual problem – asgs Nov 04 '17 at 16:23
  • I suppose by some pedantic definition it could be, but I would say that is probably being far too literal - and that, in a situation like this, we should assume that, unless the OP said they were willing to uninstall the drivers, they want to fix the problem and keep the drivers. – underscore_d Mar 04 '18 at 19:06
