Testing r100 with 2.6.32.2 kernel and F12 userspace

KMS correctly initialises DVI-0 to its native 1280x1024 resolution. However, compiz fails to run:

Textured video seems to work OK, but xine-ui's on-screen display still stops the X server from responding. Basically, the dmesg log fills up with messages like:

and you become unable to click on anything any more, although you can still move the mouse pointer. Switching to a console and SIGHUPing the Xorg process restores control.

3D on r1xx and r2xx may have regressed in some cases since the transition to KMS support as fewer people test the older hardware. If you are seeing regressions please report bugs:
https://bugs.freedesktop.org

Apart from that, 3D support on r1xx and r2xx is pretty much stable and feature complete.
