Public bug reported:

The "Ubuntu on Xorg" login option does not work on Ubuntu Desktop for Pi
mantic images. The following stanza (present in RaspiOS) needs adding to
the Xorg configuration (which is probably best done under ubuntu-raspi-
settings-desktop):

  Section "OutputClass"
    Identifier "vc4"
    MatchDriver "vc4"
    Driver "modesetting"
    Option "PrimaryGPU" "true"
  EndSection

** Affects: ubuntu-raspi-settings (Ubuntu)
     Importance: Undecided
     Assignee: Dave Jones (waveform)
         Status: Confirmed


** Tags: foundations-todo raspi-image

** Changed in: ubuntu-raspi-settings (Ubuntu)
