How do I restore my GUI? No tty, gdm3, or HDMI [duplicate]

  • 772

All the graphics-related functionality of my Ubuntu installation is corrupted. I have several problems but I think the root cause of all them maybe the same. Here are my problems:

  • I can't switch to tty terminals. Alt+Ctrl+f[1-12] just freezes my machine and I need to hard reboot.
  • I can't activate gdm3. When I do so, I just get login loop and need to go back to lightdm.
  • attach/detach HDMI freezes my machine and I need to hard reboot it.

Edit: I checked log with journalctl -b -1 -x and found this error:

*ERROR* atombios stuck in loop for more than 5secs aborting

PS: I have Intel HD graphics + AMD Graphics on my notebook.

gdm graphics tty tlp

  1. Well, as I have guessed the solution to all my problems was same: I removed tlp package and now I'm doing fine.
