Created attachment 143941 [details] Logs, as described in https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html Standard Gnome-session not starting, after login it goes directly back to login prompt. Ubuntu with wayland is working. Cinnamon is not working. After purge of amdgpu, everything is back to normal.
Can you try a newer driver? 18.30 is pretty old and likely doesn't support 18.04.2.
