I had an old ATI graphic card and was using the proprietary drivers on Ubuntu 14.04. I replaced the card with a Geforce 750 ti and Ubuntu doesn't start anymore. I cannot open a login screen with CTRL+ALT+F1, the system is totally locked.

My idea is to replace the card with the old one, uninstall the proprietary drivers and, afterwards, reinsert the new card and reinstall the correct drivers.

Would this procedure work? Is there an alternative one that does not force me to replace the hardware?

In case you had the proprietary AMD drivers installed, first remove them.

Highlight the Ubuntu entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 to the end of the linux line - press F10 to boot.
On login screen press Ctrl+Alt+F1 ... enter user name and password ...

Now execute the following commands :

sudo apt-get purge fglrx*  
sudo reboot

Install the latest stable NVIDIA drivers 352 from the Ubuntu repositories.

Highlight the Ubuntu entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 to the end of the linux line - press F10 to boot.
On login screen press Ctrl+Alt+F1 ... enter user name and password ...

Now execute the following commands :

sudo apt-get update
sudo apt-get install nvidia-352
sudo reboot

  • Ok thanks, fixed, but I used only half of your answer. The reason is that, with a German keyboard, I could not find a way to write a "=" character in the grub editor! NO WAY! All the rest worked NOTE: I had to ad a "*" to "sudo apt-get purge fglrx" – marco Jan 07 '16 at 14:01
  • @marco : You're welcome - I add the * to the command in the answer ... enjoy ubuntu experience ! :) – cl-netbox Jan 07 '16 at 14:13
