Hi there!

After watching on Launchpad bug #1365336
<https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1365336>, I've
created the following udev rule to tag kernel device /dev/dri/card0 (from a
NVIDIA graphics card) as "master-of-seat":

SUBSYSTEM=="drm", KERNEL=="card[0-9]*", TAG+="master-of-seat

I would like to make it more restrict to NVIDIA cards, so I would update it
to this form:

SUBSYSTEM=="drm", KERNEL=="card[0-9]*", ATTRS{vendor}=="0x10de",
TAG+="master-of-seat

An even more restrict rule for NVIDIA cards with proprietary drivers is the
following:

SUBSYSTEM=="drm", KERNEL=="card[0-9]*", ATTRS{vendor}=="0x10de",
DRIVER=="nvidia", TAG+="master-of-seat

Could you please replace your current udev rule with each one of the above
ones with your NVIDIA cards and see if your multiseat setup still works?

In each case, complete the rule with your own SEAT_ID tags.

Thanks in advance!
