Hmm Hi!

i think, it isn a problem of x.org. with fluxbox it works very fine. so sorry 
about that.

but the resolution problem is a x.org problem i think. without plugged in the 
external monitor i get the 1280x800 resolution on my samsung notebook. but 
with it crashed with:

(1280x800,MonitorQ) mode clock 83.46MHz exceeds DDC maximum 80MHz

Whats wrong, why does it work without external display, but wont with it?

Also i cant get dri enabled with xinerama. without it works. do i have to 
select it in only one device section (i read that xinerama work only with one 
screen dri enabled)?

thank you for your help

here my 2 different xorg.conf
