I recently upgraded to an RX 480 and installed Ubuntu 16.10 gnome desktop. Because the default/open source drivers were glitchy, i downloaded the latest drivers from AMD's website, the 16.50 drivers, and after installing and rebooting all i can get to is TTY and Grub. If i do sudo service gdm restart it freezes. How do i fix this?

  • Exactly what AMD drivers have you installed. A link would also be helpful. –  Dec 30 '16 at 18:58

You should be able to boot into the multiuser target with sudo systemctl set-default multi-user.target and rebooting. Then go back to your AMD graphics installer binary and run it again, this time passing --uninstall to it.

I have this exact problem and am just using glitchy open source drivers for my graphics card since it is newer. Older graphics card have great support, I just happen to have a niche laptop. Remember to set your boot target back with sudo systemctl set-default graphical.target

  • This did not help. Now I just get a black screen after boot up until I do Ctrl alt f2 – Captain Chicken Dec 30 '16 at 20:31
  • This was how to uninstall the drivers that were just installed to revert to the old drivers. Do you have the original drivers installed? Here is a link to the official documentation on working with AMD fglrx drivers: https://help.ubuntu.com/community/BinaryDriverHowto/AMD – Kyle H Dec 30 '16 at 20:33
  • When I tried "suds apt-get install fglrx I got no installation candidate – Captain Chicken Dec 30 '16 at 20:52
