Ah yes, adding the Virtual entry gives me access to the 1900x1200 mode.
Actually, I'd already added it to the other Depths before but not to
Depth 24 for some reason. Must have got distracted in the middle of
What I'm still not getting is Panning. The full 1900x1200 now appears
on the external monitor while the laptop LVDS only shows the upper
1024x768 corner. I understood that moving the mouse against the edge of
the smaller screen is suppose to cause panning within the extent of the
full 1900x1200, but that isn't happening. The LVDS edges are fixed.

Is panning known to have stopped working like this?
