Ubuntu stuck in low resolution after UNinstalling / disabling NVidia drivers

drivers nvidia uninstall resolution

Tried the Nvidia driver, installed using the Additional Drivers panel. Didn't like it much; the CPU seemed to overheat more and the brightness controls stopped working. Also selecting a second display is a pain using that horrible NVidia settings thing.

So wanted to disabled it again.. problem is, UBuntu is then stuck in either 640x480 or 800x600 (second time I tried to install it back and then remove again).

How can I get this back the way it was? The original Ubuntu drivers worked just fine, allowing me to run Unity and games properly. I tried a xserver-xorg reconfigure but this didn't do anything. (No xorg.conf file either).

This is on a Lenovo Thinkpad T410i

Solution 1:

Make sure your nouveau driver is not black-listed.

I had the same problem as you after installing the NVIDIA driver manually and removing it after not enjoying it.

You need to take a look in your /etc/modprobe.d folder. You may well find a file named something like "nvidia-installer-disable-nouveau.conf". You will need to be root to delete this so fire up a terminal and punch in:

sudo rm /etc/modprobe.d/nvidia-installer-disable-nouveau.conf

Obviously change this to whatever your file is called, if different. After that reboot and you should be good to go! I didn't use the restricted driver installer though, I downloaded the driver straight from NVIDIA so the file may be different or the lines:

blacklist nouveau

options nouveau modeset=0

May well be in a different file, so have a nosey around the modprobe.d folder.

Hope that helps.

Solution 2:

i've removed nvidia drivers and had the same low resolution on one of monitors. surprisingly it helped to delete /etc/X11/xorg.conf file.
