VIA Openchrome/OpenSuse 11.1

The problem: Super slow X on OpenSuse 11.1 on Acer Aspire T135. It would take a minute to move the mouse. Forget about clicking. Neither the VIA drivers nor openchrome would compile (XINERAMA snafu => X sources not installed correctly).

Even Vesa ran better.

The magic incantation:

Install xorg sources and most importantly, xorg-x11-server-sdk-7.4-17.6.1 . Then you can compile and use openchrome. Also remember to remove any existing openchrome drivers.

I used openchrome revision 811.

Additionally, hand edit xorg.conf because (on the older driver) scan frequencies for Dell 1800fp were not right. Otherwise 800x600.

HorizSync 31-70
VertRefresh 55-75

And set max resolution to 1280x1024. Otherwise 1440x1050 is used and you wont be able to see the whole screen.
