Hi,

I'm using Ubuntu Server 8.04 and I'm having trouble getting 3D acceleration working on an Epia SN board with Chrome 9 integrated graphics.

I installed the OpenChrome driver but had no luck (I think it doesn't yet support Chrome 9), so I tried using the patches provided by VIA at http://linux.via.com.tw/support.

After following the instructions in the patch archive I ended up with via_chrome9 and drm modules which load without error. Unfortunately, while I can run glxgears (at 135 fps - a speed which was reached with the OpenChrome driver) I can't run glxinfo without a crash:

Program received signal SIGSEGV, Segmentation fault.

I'm guessing glxgears is still running in software and glxinfo crashes on trying to use the hardware.

Looking on the forums other people seem to have problems with OpenChrome as well.

- Has anyone managed to get the VIA-provided drivers to work?
- Is there any 3D code in X that would need rebuilding after the VIA patches?
