I'm not sure where pciconf gets it's data. I would actaully like to look at that. > X server: "ATI Technologies Inc RV380 [Radeon X600 (PCIE)]" This comes from /usr/local/share/pciids/pci.ids > drm driver: "ATI Radeon RV370 X600 Pro" This comes from drm's own internal tables.

Ok, so it isn't the gart caching... Can you get me a pointer to a screenshot? What is garbled exactly? Is the damage constrained to specific windows or it it the entire framebuffer? robert. > -- > Greg Rivers -- Robert Noland <rnol...@freebsd.org> FreeBSD
