I'm trying to set up a multiseat configuration on a single video card (Nvidia GTX 680) under Kubuntu 14.04.
I can run two x-screens for one user, what nvidia-settings
natively supports. So I think this should be possible.
Unfortunately my second screen stays black after booting but when I start another x-server in the second terminal it shows up at the second screen and the first one stays black.
Is there a way to show both at the same time?
My current settings are:
lightdm.conf:
[LightDM]
minimum-display-number=0
minimum-vt=7
[SeatDefaults]
xserver-command=X
allow-guest=false
[Seat:0]
xserver-command=X :0
xserver-config=xorg_seat0.conf
[Seat:1]
xserver-command=X :1 -sharevts
xserver-config=xorg_seat1.conf
xorg_seat0.conf:
