Follow this post to get into recovery mode:

How do I boot into recovery mode?

In essence:

  • Switch on your computer.
  • Wait until the BIOS has finished loading, or has almost finished. (During this time you will probably see a logo of your computer manufacturer.)
  • Quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.) **
  • Select the line which starts with "Advanced options". *
  • Select the line ending with "(recovery mode)"

And then remove all NVIDIA propietary drivers following this other post:

How can I uninstall a nvidia driver completely ?


sudo apt-get purge nvidia*
sudo apt-get install ubuntu-desktop
sudo rm /etc/X11/xorg.conf
echo 'nouveau' | sudo tee -a /etc/modules

Reboot your system.


Perform additionally these 2 steps to reconfigure X with the nouveau driver:

sudo apt-get install nouveau-firmware
sudo dpkg-reconfigure xserver-xorg

and reboot!

  • HI Eduardo Lopez Thank you for your reply I did the steps but for " sudo rm /etc/X11/xorg.conf " the xorg.conf file is exist the the X11 folder and the problem still the same – Salim Jan 28 '16 at 14:22
  • Excuse me, I didn't catch that: What happens with the step where you delete the xorg.conf? You receive an error? – Eduardo López Jan 28 '16 at 14:40
  • I mean no file with xorg.conf name in /etc/X11 folder – Salim Jan 28 '16 at 15:59
  • But did you anyway executed the last step and rebooted? Issue this command in the command prompt, it should tell you where the xorg.conf file ist: "sudo find / -name 'xorg.conf'" – Eduardo López Jan 28 '16 at 16:25
  • Hi Eduardo Yes I did , and I did try to find the file as you told me and the result came no file found – Salim Jan 28 '16 at 17:28
