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.

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

lifesaver. I actually found
/etc/X11/xorg.conf.failsafe
and copied that over to xorg.conf Feb 18, 2016 at 19:37
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.

1I 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).– MárcioApr 18, 2014 at 21:28

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.

xorg.conf
file by runningsudo rm /etc/X11/xorg.conf
nvidia-current
instead ofnvidia-331
Option "UseEDID" "false"
to theSection "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
