Public bug reported: Test this with Ubuntu 20.04 (Mate) beta installer. Kernel is 5.4.0-24 (if I remember right). All works fine, but after returning from suspend the display is flickering. For the installer / USB stick usage that might not be a problem, but the same behaviour in a normal environment would be a no go (for using suspend)
