I'm using a single nvidia Quadro FX 3700 card on my system.
suggests that changes should be made to the lightdm.conf and xorg.conf files. When I made the suggested changes to xorg.conf and the following
[LightDM] displays=display0 display1 [display0] xserver=xserver0 [display1] xserver=xserver1 [xserver0] layout=layout0 [xserver1] layout=layout1
changes to lightdm.conf, from what I remember, ubuntu failed to detect my second monitor. Other information I've found gives directions for older versions of ubuntu which use different display managers (gdm as opposed to lightdm), which doesn't help. I also tried using
but it didn't detect my second monitor so I couldn't follow the directions given. In the first thread I linked to somebody claimed "In terms with running multiple X sessions from one video card this is currently unsupported." which suggests that it might not be possible with my current setup.
I don't really know what I'm doing, I'm just trying to follow any resources that are available. So how do I do it? Is it even possible with 12.04 and only one video card?
