[Openchrome-users] Low quality 2D in ARCH Linux + openchrome + VIA K8M890

[daz]

Your driver is *not* the same.

Your chipset is K8M800 and the VIA xorg driver xf86-video-via supports this 
chipset.

My chipset is K8M890 and the VIA xorg driver *DOES NOT* support this chipset. 
Instead, one needs to use the openchrome driver.

Both available from the arch repos, both intended for separate chipsets.

Thanks anyway.

I still need a solution.
