Only when using v4.15, if I use the hwe kernel 4.18 on Bionic it passes. I have strong belief this kernel fix to be a potential good candidate, but I need to run a bisection to confirm my assumption : commit 140bcaa23a1c37b694910424075a15e009120dbe Author: Thomas Hellstrom <thellst...@vmware.com> Date: Thu Mar 8 10:07:37 2018 +0100 drm/vmwgfx: Fix black screen and device errors when running without fbdev When we are running without fbdev, transitioning from the login screen to X or gnome-shell/wayland will cause a vt switch and the driver will disable svga mode, losing all modesetting resources. However, the kms atomic state does not reflect that and may think that a crtc is still turned on, which will cause device errors when we try to bind an fb to the crtc, and the screen will remain black. Fix this by turning off all kms resources before disabling svga mode.
