Tri-Head with T430s, NVS 5200 and Dock

Hi,

I'm looking for a way to connect two displays (DP and DVI) to my docked (Lenovo ThinkPad Mini Dock Plus) T430s while using the internal screen as well. Thats the point I'm pretty much stuck right now. I managed to connect the external Displays (without using any of the nvidia stuff), but I can't use all three displays at the same time. I really have no idea how to proceed and would appreciate your help

Thanks

Xrandr is detecting it. Will it work if you use xrandr to handle the config?

Thats what I'm doing at the moment. After booting LVDS1 and DP2 are active. As soon as I try to activate DP3 I get this:

$ xrandr --output DP3 --auto
xrandr: Configure crtc 2 failed

I'm on to something here.

Bad news here and here.

Turns out that the DisplayPort is disabled once DVI is in use. Explains the error. I only see DP2, DP3 and LVDS-1 in your output.

hmmm.....
