The dynamic setup doesn't do anything, since there's only one
device/screen/monitor recognized by xrandr:
lynch at localhost ~ $ xrandr -q
SZ: Pixels Physical Refresh
*0 800 x 600 ( 383mm x 302mm ) *75
1 640 x 480 ( 383mm x 302mm ) 75
2 800 x 1200 ( 383mm x 302mm ) 75
Current rotation - normal
Current reflection - none
Rotations possible - normal left inverted right
Reflections possible - none
lynch at localhost ~ $
I had higher sizes with different settings in xorg.conf, but nothing
is making this other monitor show up...
The static setup also does nothing useful so far...

my home desk :-(
