[Openchrome-users] New 2133 User

[Varol Okan]

Hello,

I am new to this list so excuse if this question has been asked before ( 
though I did not see it in the archives )

I have the hp2133 Netbook and have the latest openchrome driver 
installed. Obviously I know that 3D is currently not supported but I was 
trying the following and it seems to almost work

OpenSuSE 11.1, svn version of openchrome, and via_chrome9.ko from 
http://linux.via.com.tw/support/downloadFiles.action -> Ubuntu 8.10 source.

The via_chrome9 modules compiles and I can load it without any problems. 
When I try to use glxgears, or glxinfo I get:
>  glxinfo

Looking at dmesg I see :

Can any one tell me what to do next ?
