It seems that Intel driver for Xorg allocates virtual destop as maximum rectangular size of biggest attached screen. In my example, I have:
- 1920*1200 LCD monitor connected via VGA (sic! x200 doesn't have DVI)
- 1280*800 internal LCD display
I want to have VGA output above internal LVDS with something like
xrandr --output VGA --auto --above LVDSIt should be 1290*2000 = 1920*(1200+800) so I had to add following in /etc/X11/xorg.conf:
Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" SubSection "Display" Virtual 1920 2000 EndSubSection EndSectionNice and simple. I really love new x.org configuration files with much less clutter...
