[systemd-devel] Automatic multi-seat HP T100 zero client

[Matthew Cox]

Thanks for the udl vs udlfb suggestion. I've added udlfb to the
modprobe blacklist conf file and the system now works as desired. Full
screen youtube videos def do chew a lot of CPU on the HP t100 on a
core i3-2120. What's the min kernel version that you'd recommend based
on getting the updated udl driver, and what kind of perf increase can
be expected? The system is currently on 3.7.10.
