Also confirming that removing xserver-xorg-video-intel solved the problem for me too.

I did not also have /etc/X11/xorg.conf.d/20-intel.conf. However, I did have /etc/X11/xorg.conf.d/01-amdgpu-pro-px.conf which was trying to load the intel driver that was just removed:

  jsalvo@rig01:~$ cat ~/xorg.conf.d-01-amdgpu-pro-px.conf
  Section "ServerFlags"
        Option "AutoAddGPU" "off"
  EndSection

  Section "Device"
        Identifier "Intel"
        Driver "intel"
  EndSection

  Section "Files"
    ModulePath "/usr/lib/xorg/modules"
  EndSection

Have to remove that file as well and then also do a:

  sudo apt purge xserver-xorg-video-amdgpu-pro

... as the amdgpu-pro was installed when it was on 16.04 LTS, before the upgrade to 20.04 LTS.
