Bug description:
  [Impact]

  gdm fails to start in a VMware Horizon VDI environment, with Nvidia
  GRID gpus passed into the VDIs.

  Downgrading mutter from 3.36.9-0ubuntu0.20.04.1 to 3.36.1-3ubuntu3 in
  -release fixes the issue, and the issue does not occur with
  3.36.7+git20201123-0.20.04.1.

  Currently looking into what landed in bug 1919143 and bug 1905825.
