[Intel-gfx] running two individual displays on a wide screen monitors

Tue Nov 3 19:43:15 CET 2009

Hi,

How can get two independent desktops ( no cloned or extended) working
with the following display resolution 1680x1050? 

I was able to get the independent desktops configuration working using
the i810 driver only, if i use the "intel"  driver it will fail . But my
now problem is that I cannot get the desired display resolution with the
i810 chipset, I already tried the 915resolution suggestions but no luck
. It seems that the new Intel driver supports wide screen resolutions
but two individual desktops no :(.

So, Is it possible to have all these  things working together ? intel
945gm + redhat enterprise 5.2 + 1068x1050 wide screen resolution + two
individual displays (no cloned or extended)

testbed

 	 Chipset	 Model	 Monitor	 Driver	 OS	 Misc	
	945GM	 Kontron 986LCD	 ACER DVI	 OS 	Redhat
enterprise 5.2	  off board  ADD2 video card	
						The two monitors will be
connected to this card only the onboard vga connector is not used.	

here is my xorg.conf
