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

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
