This is needed for generic DRM devices like the VirtualBox vboxvideo
|
|
driver, which exposes itself as a generic, ID-less DRM device at
|
|
/dev/dri/card0 (after applying this commit):
|
|
$ udevadm info --query=all --path \
|
|
/sys/devices/pci0000:00/0000:00:02.0/drm/card0
|
|
P: /devices/pci0000:00/0000:00:02.0/drm/card0

Without this patch, the capabilities for a seat on a VirtualBox
|
|
installation of systemd v219 incorrectly show it as non-graphical, even
|
|
though I can type these commands from an xterm:
|
|
$ loginctl show-seat seat0
|
|
Id=seat0
|
|
CanMultiSession=yes
|
|
CanTTY=yes
|
|
CanGraphical=no
|
|
…
