too high resolutions in xinerama for GF2mx ?

[GodFlesh]

Hi,

I use a xinerama setup, on a GF2mx card.
Some days ago i was still using old monitors, in 1024x768 and 1024x768
then i found at work two nice iiyama vision master pro 450, bigger and with higher resolutions.

I connected tem to my card, changed my XF86config for correct ModeLines, and it's not working. My second monitor stays dark. X shows up, but like if i had only one monitor, not taking into account xinerama setup.

Please help.

video card : GeForce2mx AGP
driver version : 32bits 6111
distribution : MandrakeLinux 10.1

The geforce2mx is limited in the resolution it can display on the second output. The card was made for max a resolution of 1280x1024 on the second output. The ramdac for the second output only runs at max 150MHz or something like that instead of >300MHz for the primary head. Cards that came after the geforce2mx don't have this limit.

Ok, thanks for the info.
I'm gonna try with a GF4Ti i have at home to see if it is able to handle the resolutions.

So i installed a GeForce4.

Still trying to get a working xinerama.
After a lot of search, i found the problem : it lies in the "virtual" option in my XF86confif file.
I need to put a greater value than the sum of the TWO screens in order for it to work.
But by doing so, kde panel will not extand on both screens :-(

Any idea how to solve this problem ?

I found !
Just remove (or comment) all the "virtual" lines.
Then in kde center say to use both screens.
