I installed Ubuntu 20.04 yesterday, and it frequently freezes, Everything just stops, but I can move my mouse cursor (Can't click anything though). The only thing I can do is a hard reboot.

I don't know if it's the gpu drivers issue, I couldn't find the drivers for my GPU AMD Radeon HD 8750. I'm pretty new to Linux and I could really use some help.

Encountered a similar issue a week ago, browsed many linux forums and turns out it was due to Unstable Graphic Drivers.

Backstory

I had Nouveau drivers installed, I tried to update to the latest drivers using sudo ubuntu-drivers autoinstall followed by a reboot. I was able to login successfully but couldn't click anything on the desktop but my pointer was moving, hard rebooting was the only way out.

What can be done

  1. On the login screen, type ctrl+Alt+F2 to get a TTY. Login using your name and password.
  2. Remove your graphic drivers using sudo amdgpu-pro-uninstall(In my case it was NVIDIA sudo apt-get purge nvidia*).
  3. Type in the command sudo apt-get install --reinstall xserver-xorg-video-radeon followed by
  4. sudo apt install xserver-xorg
  5. sudo update-initramfs -u -k all
  6. Reboot the system to apply the changes using sudo reboot.
  • Update to a stable/recommended driver but not to the latest driver available if you do not know the consequences. I reinstalled my OS 4 times in the last 12 months, It was an Nvidia driver issue 3 out of 4 times.
