    Guys thank you so much for all the work you put into this!!

    I happen to use RS690 chip and if I could help in any way for testing or whatever you tell me I will gladly do it!!

    Our main problem with fglrx is video support and generally 2D behaviour and performance. Also is EXA usable with the open driver?

    I am a member of the mailing list exert said above.
    And I think we can all help there a lot with the new stuff!!

    Thanks again!

    Jim

    EXA should work but I don't know about RENDER acceleration (because on the infamous rs480 RENDER does not work and these chips are very similar) and switching to console. Do they work?

    Edit: Looking at radeonhd.org logs it seems that VT switching still doesn't work but this issue is being worked on .

    i don't have render on rs480. and exa has the same cursor problem that the fglrx has. with xaa adding xaanooffscreenpixmaps works but with substituting exa to xaa won't work.

    Well I tried radeon (git 03 02 2008) from debian experimental package. 2d acceleration worked nice, however I didn't try the 3d because text console mode (ctrl alt f1) always ended up as white screen so I gave up on this driver quite fast ...

    Now I'm running radeonhd 1.1, but any advice is welcomed should I try newer radeon or radeonhd from git ? Text console is sth that I do need ...

    That raises a good point. We were thinking that basic 3d support would be more broadly useful than accelerating EXA Render, but for the IGP parts (where 3d is going to take a bit more work because they don't have vertex shaders) implementing full Render might make the open source drivers a lot more useful.

    Wolke, Dave and Alex have done the hard part -- getting the 3d engine running in the 3d driver for rotation support -- so adding the blend ops for Render might be worth doing on the 3xx/4xx engine even if we didn't extend it to R5xx/6xx immediately.

    Radeonhd from git will get you some 2d acceleration now. It needs to have CP/DRM support added to get full acceleration but depending on your CPU it might be worth moving to the latest radeonhd today.
