Extended desktop problem on Intel Graphic and OpenSUSE 11.0

Hi,

I have OpenSUSE 11.0 and connected two monitors, both with resolution 1680x1050, one connected trough analog vga cable and other trough DVI.

I have enabled in Sax2 Xinerama, but is seems that it isn’t working as I set it. On my primary monitor I have normal resolution, but on the other I see a clone of my screen and also screen is partly visible, because background seems to be bigger.

My xorg.conf file contains the following:

Can someone please help, because I searched trough all the internet for a solution and everything I’ve tried doesn’t work. Please also bear in mind, that I am no expert in this matter.

Thank you!

Could it be, that the Intel is not capable to do so (i.e. on linux) ?

Another suggestion might be to install 11.2 ; the way it handles hardware is incredible. The problem might not exist. I’ve seen true performance boosts on laptops with Intel GPU’s.
Upgrading your Xorg to the most recent might be a solution as well.

I use desktop computer and the problem is that it would involve a lot of additional work if I install 11.2 version, so this option is not best for me :\ I found also that this works for Intel GPUs, but whatever I try it isn’t solving my problem.

And also I do regular updates, so I have the newest Xorg already installed, but this doesn’t help either.

Is there any other way to solve this?

Thanks!

Has anyone else any ideas?
