    PS: Is lack of hardware accel the cause of 99% cpu on 1080p?

    (EE) AIGLX error: dlopen of r300_dri.so failed
    (EE) AIGLX: reverting to software rendering

    wonder why the s/w is looking into r300 chipset on RS780 ?

    Regards

    works now!
    drmOpenDevice: node name is /dev/dri/card0
    drmOpenDevice: open result is 7, (OK)

    720p runs full screen with 50%/40% per cpu core, 1080p runs at 99%/50% per core!!

    fglrx used to run 1080p @60%/45% per core. This is also what AMD/ATI promised with the chipset without phenom+1066 RAM. Clearly the XVideo accel needs working on.

    cpu is BE-2350 2.1 ghz with Dell 2408wfp @1920x1200.

    But atleast its mostly working (except audio which appears to be a ffmpeg issue)

    Thanks for your assistance. Please update when XVideo improvements need to be tested. I will be happy to test and report.

    Regards

    The instructions cover both radeon and radeonhd, since we're only talking about the drm (kernel) module.
    Thanks will try it out and update.

    Cheers

    Yes. I only want XVideo and acceleration for HD playback. 720p nd 1080p vids are jerky in full screen mode with 70% cpu on a 2.1ghz dual core. I would like to see it drop to 50% or below with smooth playback in full screen. I think drm is needed to gets bits of 2d accel working - or is it not?

    TIA

    Bridgman

    Yes

    lsb_release -rd
    Description: Ubuntu 8.04.2
    Release: 8.04

    2.6.24-24-generic #1 SMP Wed Apr 15 15:11:35 UTC 2009 x86_64 GNU/Linux

    My Xorg.conf is setup correct AFAIK
    installed xorg-video-ati 6.12.1 deb and followed the drm instructions in steps 2 n 3.

    Don't plan to upgrade to 8.10 in the next 3 months atleast ...

    Let me know if you want the output of any cmds to debug?

    TIA

    The instructions do not work for DRM


    drmOpenDevice: node name is /dev/dri/card0
    drmOpenDevice: open result is -1, (No such device)
    drmOpenDevice: open result is -1, (No such device)

    What do I do next?

    TIA
