Public bug reported:
I've set up a second seat via loginctl --attach, resulting in the
following udev rules:
TAG=="seat", ENV{ID_FOR_SEAT}=="drm-pci-0000_6e_00_0", ENV{ID_SEAT}="seat1"
TAG=="seat", ENV{ID_FOR_SEAT}=="input-pci-0000_6c_00_0-usb-0_11_1_0",
ENV{ID_SEAT}="seat1"
TAG=="seat", ENV{ID_FOR_SEAT}=="sound-pci-0000_6e_00_1", ENV{ID_SEAT}="seat1"
TAG=="seat", ENV{ID_FOR_SEAT}=="usb-pci-0000_6e_00_3-usb-0_1",
ENV{ID_SEAT}="seat1"
Because of #2033322, WaylandEnable=false is set in
/etc/gdm3/custom.conf.
It works great--except it does so only once. I can login on seat1 just fine,
except when I log out, the greeter doesn't come back up again, it just leaves
me with a black screen.
Can be recovered from by restarting gdm (via ssh from another box or from
seat0), but obviously that isn't ideal.
I've attached a pstree for the working case (no GUI logins, both
greeters up) and the non-working post-logout one (no GUI logins, only
seat0 hat a greeter up); please advise re. what logs to provide.
