Dual-screen setup on a Mobility FireGL 7000M7

[Ludwig Meyerhoff]

Hallo!

It actually turned the LVDS was disabled in the Monitor section (Option 
"Enable" "0").

But what I originally wanted to do was to have one additional desktop on 
:0.1. I read support for this has been removed as it should get task of 
the WM?



Saluti!
