At first, I was facing too big display problem to fix this I ran these commands as I was found this as a solution in a link.

sudo apt-get update && clear && apt-cache search nvidia-[0-9] | grep 'binary driver'

sudo apt-get purge nvidia*

sudo apt-get install nvidia-340 nvidia-settings

sudo nvidia-xconfig

After rebooting!! I am facing a black screen problem!

Please find the video on this link (link)

  • Your problem may be related to this:https://askubuntu.com/questions/162075/my-computer-boots-to-a-black-screen-what-options-do-i-have-to-fix-it. – Freax Jul 30 '20 at 09:08
  • @Freax In this case when we know the cause of the black screen it's not appropriate to select the broadest possible generic question instead of using the information that we already have. – karel Jul 30 '20 at 09:11

    @Freax thank you! I tried with that before. It did not work out. – pavanbn8 Jul 30 '20 at 09:25
  • @Freax As it turns out my answer solved the problem, and it's not a duplicate of the link that you posted in your comment. – karel Jul 30 '20 at 09:47

Let the built-in ubuntu-drivers program decide automatically which proprietary graphics drivers to install. Open the terminal and type:

sudo apt update
sudo apt remove '^nvidia'
sudo apt autoremove
sudo ubuntu-drivers install && sudo reboot

The install option of ubuntu-drivers installs drivers that are appropriate for automatic installation including their dependencies.

  • thank you for your quick response! I removed Nvidia successfully! but apt update throwing E: failed to fetch link error and could not resolve archive.ubuntu.com problem – pavanbn8 Jul 30 '20 at 09:32
  • That's a package management error. Please run sudo apt update and copy/paste the entire block of error messages into your question. I suspect there is a bad PPA line in /etc/apt/sources.list that needs to be commented out by preceding it with a # character and then try to run sudo apt update again. – karel Jul 30 '20 at 09:34
  • Thanks a lot!!! I just tried to reboot the computer after autoremove. The black screen problem is solved!! It is back to a big display. – pavanbn8 Jul 30 '20 at 09:40
  • Sure!! I will do it!! Thank you so much for your great help! Now the big problem is solved!! Next, I will try to fix the big screen issue!! – pavanbn8 Jul 30 '20 at 09:48
  • The first step to solving the big screen issue is to run xrandr command and this will show what your available display resolution options are. xrandr is used to set the size, orientation and/or reflection of the outputs for a screen. It can also set the screen size. For more information run man xrandr. – karel Jul 30 '20 at 09:51
  • That's great!! Thank you. I will try this out Karel! – pavanbn8 Jul 30 '20 at 09:57
  • Karel! You solution "sudo ubuntu-drivers autoinstall && sudo reboot" is solved big screen problem too! Thanks a lot!! – pavanbn8 Aug 05 '20 at 02:55
