Stuck at 640x480 resolution;
Okay so today I turn on my pc and my monitor is stuck at 640x480, I attempt to change the display settings but it wont let me change any of the options. I tried to switch to a different Nvidia driver (open source and proprietary) to no avail, tried switching back to the Nouveau driver too, still no luck. Not sure what caused this, but I think its happened due to something that updated, I remember when I was last on my pc letting it do some updates. How can I diagnose this and fix it?
Am on Xbuntu Distributor ID: Ubuntu Description: Ubuntu 18.04.2 LTS Release: 18.04 Codename: bionic
This worked for me:
- Search Nvidia packages
$ dpkg -l | grep -i nvidia - Remove all the Nvidia drivers
$ sudo apt-get remove --purge '^nvidia-.*' - Go to: Software Updates⇢Additional Drivers⇢select first one⇢Apply Changes⇢reboot
This looks like nomodeset.
Make sure that it isn't set somwhere in your ubuntu configuration
grep nomodeset /etc/ -rs
This should print by default only:
GRUB_CMDLINE_LINUX_RECOVERY="$GRUB_CMDLINE_LINUX_RECOVERY nomodeset"
If it appears somwhere else, i.e. in /etc/default/grub - remove it and update grub configuration with
sudo update-grub2
Then reboot.
Also check which graphics driver is in use.
lspci -v
Look for your graphics card or VGA string sections.
In case it's
Kernel driver in use: nouveau
open applications menu and go to Updates -> Settings -> Additional Drivers
or via terminal:
/usr/bin/python3 /usr/bin/software-properties-gtk --open-tab 4
and install one of proprietary drivers available.
Keep in mind that after switching drivers you need to reboot your PC.
