OpenSUSE 11.1 problems with dual-head / xinerama

just installed OpenSUSE 11.1 on my IBM Thinkpad R51.
I want to use an CRT Monitor in addition to the Laptop’s LCD in Xinerama dual-head mode.
The laptop’s graphiccard is an ATI Mobility Radeon 7500 32MB (RV 250), installed with the OpenSource-driver Mesa Project (2.1 Mesa 7.2)delivered by the OpenSUSE 11.1 default installation.
Since there is not an specific ATI driver for my graphic card model, I have read in some other forums that this driver is the best or only one.
My problem is the Xinerama Mode doesnt work.
Although I have enabled this mode in yast/sax
the card uses the clone mode.

With my old SuSE (10.0) Xinermara has worked perfect.

Thanks for any help.

I have an nVidia card and had to “mod” and .inf file on the installer for the laptop version of my video card - it may come down to that. The drivers are all the same (more or less) but there isn’t a laptop entry in the .inf file it won’t istall on your laptop.

Maybe you can find modded files for your laptop video card and use the ATI driver?

Have you had any luck with this? I am having exactly the same problem with an external LCD plugged into a Compaq laptop with an Intel 855GM card - no matter what I try, it simply clones the screen at 1024x768.

I always recommend XRandR - it works perfectly for me (1280800 laptop+16001200 VGA-monitor).
You have Intel card, so I think it has XRandR capabilities.

I don’t know about ATI, but with open drivers think it is supported too.
