Xorg login broken under mantic

[Dave Jones]

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

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubuntu-raspi-settings - 24.04.1

---------------
ubuntu-raspi-settings (24.04.1) noble; urgency=medium

  * Tidying up cruft from ubuntu-settings which is not used by
    ubuntu-raspi-settings:
    - d/ubuntu-touch-settings.gsettings-override removed
    - d/ubuntu-settings.* removed
    - d/maintscript removed
    - d/control, d/rules removed dh-translations dependency
    - po/* removed
    - data/ubuntu/* removed
    - data/ubuntu-wayland/* removed

  * 99-vc4-primary.conf: Fix Ubuntu on Xorg session (LP: #2046147)
  * raspi-lz4.conf: removed obsolete hack (LP #1958148 fixed this properly
    by lowering compression levels in initramfs-tools)
