Video resolution on multiple monitors


Opensuse11, nvidia driver (NVIDIA-Linux-x86_64-173.14.05-pkg2.run.) stand alone works great. When I am at work, I am connected to a matrox triplehead to go, connected to 3 22' dell ewp widescreen monitors. Ubuntu had the same problem, fedora worked great but wanna stick with suse, but here is the issue.

Using the nvidia-settings, I see the matrox (shows as one 3840x1024 desktop) and the laptop. I tried with the laptop on, disabled, etc. but same results.

The desktop get's spanned right, but the resolution is horrible and I just noticed on the XScreen 0 of the nvidia config I see this;
Dimensions:3840x1024 pixels (412x313 millimeters)
Resolution: 237x83 dots per inch

Which I guess is the problem. Fonts I made 6pt and are decent, but images, Firefox icons are HUGE, and this setup is not workable. Does anyone know a fix? The xorg.conf file (the video parts) looks like this;

I think you may need to add screen1 as well then, because the resoluton changes from one screen to the other but I am not sure. What I do know is that Linux is lacking in multiple monitor support at least in ease of use compared to other MS and Apple
