anybody using VIA K8M890 vga and the openchrome driver?

I'm using the openchrome driver from the arch extra repo.

NOTE THIS IS NOT THE xserver-xorg-video-openchrome driver, it is the newer one based on the svn source code tree.

Does anyone have a successful configuration using this combination....

Using pacman -S openchrome. Installed fine so I reconfigured my xorg.conf and I restarted X.

However, repainting windows and moving windows is extremely slow. For example if I open a Konsole window for which the schema is transparent, it takes about 2 seconds for the background to be painted inside the Konsole window.

Using the stock vesa driver is much more responsive. How can this be? Surely I have something configured incorrectly. Surely the vesa driver cannot outperform the openchrome dedicated VIA chipset driver.

I have to take the 5th amendment on the warnings/errors - no idea what they mean or if they are significant.

EDIT:
The font rendering and general quality of the display if far superior to the VESA driver, however the 2D "stuff" seems to be configured incorrectly/not at all. Can anyone help please.

Looking at the log seems that you have drm-problem.

Do you have libdrm and unichrome-dri packages installed?

pacman -Q|grep drm
libdrm 2.3.0-1
