Dear all,

sorry for a newbie's question. I have installed the openchrome driver for my VIA Unichrome 3D (P4M890 chipset) graphics card on a Xubuntu 7.10 system. However, hardware acceleration does not work, and any graphics application consumes a lot of CPU power.

When I run glxinfo in verbose mode, it says

libGL: XF86DRIGetClientDriverName: 5.0.0 unichrome (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/unichrome_dri.so
libGL error: dlopen /usr/lib/dri/unichrome_dri.so failed (/usr/lib/dri/unichrome_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: unichrome_dri.so
name of display: :0.0
display: :0  screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
...

A similar thing is reported in /var/log/Xorg.0.log:

(II) CHROME(0): direct rendering enabled
...
(EE) AIGLX error: dlopen of /usr/lib/dri/unichrome_dri.so failed (/usr/lib/dri/unichrome_dri.so: cannot open sh
ared object file: No such file or directory)
(EE) AIGLX: reverting to software rendering

Well it is pretty obvious. It tries to load /usr/lib/dri/unichrome_dri.so, which does not exist, and then falls back to software rendering. But how do I tell it to use a different driver library instead? And what library? (And why didn't it work from the start?)

Any help is greatly appreciated.

Best regards
Tom
