Anybody using openchrome driver?

I am using the OpenChrome driver for my VIA Technologies, Inc. CN400/PM800/PM880/PN800/PN880 [S3 UniChrome Pro] adapter. However, there are some graphical artifacts on the screen. None of the icons like the volume control and network manager are shown; only black boxes are shown.

Sometimes my display got corrupted. Without dri all works FINE. Tried with/without xorg.conf, changed EXA to XAA -- still the same. XAA is slower than EXA.
Unichrome-dri installed from extra. mesa, libgl, libdrm is from AUR (GIT).

Re: Anybody using openchrome driver?

What happens if you set "EnableAGPDMA" to "false"?
The unichrome-dri driver is known to have some problems as it has not been developed very actively lately. There's also another X.org driver for VIA chipsets, the UniChrome driver http://cgit.freedesktop.org/~libv/xf86-video-unichrome. You'll have to get the GIT version and build it yourself, the official releases are outdated.

"EnableAGPDMA" to "false" = same result.
What about xf86-video-unichrome - thanks, i'll try it out.
