Made the mistake of trying to manually update my Nvidia driver on Ubuntu Mate 16.04 LTS. Anyways the update failed and now I am left with a screen resolution that is wrong(too low resolution) How do I restore the proper resolution? The attached shows I am still running the older 384 driver.

And this is my xorg file

  • Please post the output of xrandr. – marko Oct 7 '17 at 20:40

You can remove the nVidia drivers and that will restore the open source nouveau drivers and the config your system was previously in (before the installation):

Launch a terminal and run:

sudo apt-get remove --purge nvidia*

or respond to my comment above and post the output of xrandr and we can show you how to change the resolution over the command line.

  • xrandr: Failed to get size of gamma for output default Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768 default connected primary 1024x768+0+0 0mm x 0mm 1024x768 76.00* – Bachalo Oct 8 '17 at 1:49
  • Thanks. Just want to confirm. Prior to making this mistake with a manual install I ALWAYS used Software & Updates to do any driver updates. I also recall that I ALWAYS had issues with the nouveau driver and stuck with the NVIDIA Binary driver as in my attached screen shot. 384.90 was last working version for me. – Bachalo Oct 8 '17 at 1:50
  • Is there a default 'uninstall' command or should there be an uninstall option if I try and run the above installer again? – Bachalo Oct 8 '17 at 2:21
  • Just use this and restart your computer: sudo apt-get remove --purge nvidia* BTW, you can also try selecting a different version of the NVIDIA driver before running the command I suggested. – marko Oct 8 '17 at 2:25
  • Thanks. Back in action. Only remaining issue is that I have lost my custom fan settings in NVIDIA XServer software. Don't recall if this has something to do with Coolbits or?? – Bachalo Oct 8 '17 at 2:57
