As long as you are capable of identifying when things work or not, and know how to revert to an older set of packages, and can tolerate the odd hang or crash, there is not much problem in using xorg-edgers IMO.

The Lucid branch will start soon, as soon as there will be some new Lucid Xorg packages, next week probably. For now only the Lucid kernel has been updated for what the Xorg stack is concerned.

Thank You for all the good work and effort You've made! I'll probably wait for the end of next week to embark on Lucid ship.

7a.) Now you must compile and install libdrm_radeon:

git clone git:anongit.freedesktop.org/mesa/drm && cd drm && ./autogen.sh --prefix=/usr --enable-radeon-experimental-api && sudo make install && cd ..

Double "//" missing after "git:".

Ok, tried it (on Sapphire HD 4350), but it failed with

(II) RADEON(0): RADEONRestoreMemMapRegisters() :
(II) RADEON(0): MC_FB_LOCATION : 0x000f0000 0x00ef00e0
(II) RADEON(0): MC_AGP_LOCATION : 0x0003ffff
(EE) RADEON(0): Timeout trying to update memory controller settings !
(EE) RADEON(0): You will probably crash now ...

Tried on 2.6.32-rc6 with everything in your how-to, except the "pull from drm-linus". I assumed (probably wrongly) that the stuff is in the latest rc.

With 2.6.32-rc7 it works! I just refreshed all gits and now there's a picture on both screens, with acceleration on multiple VT's.

The only thing that's different it's that displays are now switched - what used to be DVI-0 is now DVI-1 and vice versa. I updated the randr startup script and now everything is back to normal.

The VT switching is indeed fast. Only when I switch back to graphic mode the repaint is somewhat visibly slow. But once the picture is on the screen the speed is back to normal.

Thanks a bunch. It feels great that my wife can have acceleration in her session, which until now was not possible (the scrolling in web browser was really a pain).
