I'm still trying to figure this out! Two screens -> one screen is easy. When I undock, I just run: $ xrandr -s 1920x1200 to set the resolution to that of my laptop LCD. All good.
When I dock however, I have to run this sequence of commands: $ ./nv-control-dpy --probe-dpys $ ./nv-control-dpy --set-associated-dpys 0x50000 $ ./nv-control-dpy --add-metamode "DFP-2: nvidia-auto-select @1920x1200 +0+0, DFP-0: nvidia-auto-select @1920x1200 +1920+0" $ xrandr -s 0 -r 118 The output of probe-dpys gives me the mask to use, and the output of add-metamode gives me "118" which I pass on to xrandr. This lays out the monitors in the right order, but now the external LCD is black except for the cursor! There's stuff on it (I can drag windows to and from it, click on icons)... Any more ideas?
