I just noticed your AMD GPU is a "Renoir" which isn't fully supported until kernel 5.5, and you have kernel 5.4. So it might be useful to try a newer kernel. Please try:
sudo apt install linux-generic-hwe-20.04-edge and then reboot. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1906449 Title: [nvidia] [amdgpu] Xorg randomly freezes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1906449/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
