    Re: Desktop Effects working in jaunty on ppc?

    That's good to know. What needs to be changed from the default kernel build to get it to work?

    [Edit: I found your post that describes the workaround: http://ubuntuforums.org/showthread.php?t=1145849]

    Yes, I didn't change a thing--just copied the old config to the new kernel.

    I'm happy to report that it works with such a configuration, as I'm running it now!

    One thing that I should mention to other readers that wasn't clear to me at first is that you must compile a vanilla kernel (i.e. from kernel.org), as ubuntu patches cause the bug.

    thanks a lot !
    I miss the compiz effect so much. It's will be my first kernel compilation but i'll try this week-end (with the old kernel configuration, of course) and i'll post the result here

    Re: Desktop Effects working in jaunty on ppc?

    One side-effect I've discovered in the past few days is that after suspend/restoring my laptop, desktop effects have to be restarted manually. I'm currently running kubuntu, which uses a different compositor; it may be different for gnome/compiz. If you're running a laptop, let me know if you experience this as well.

    Re: Desktop Effects working in jaunty on ppc?

    Another bug filed on this issue (https://bugs.launchpad.net/ubuntu/+s...42/comments/22) suggests using the radeon card as a PCI device as a less drastic workaround. It only requires editing xorg.conf, rather than compiling a new kernel.

    [Edit: So far, this workaround works!]

    Re: Desktop Effects working in jaunty on ppc?

    to compile a new kernel is not working for me.
    I have just installed kernel 2.6.29.2 from kernel.org (with the old .config) and compiz always don't want to work.

    The solution with "Option "BusType" "PCI"" in xorg.conf don't bring, in my case, more success.

    My mac is a G4 2 x 1,2 Ghz PPC with a graphic card
    ATI Technologies Inc Radeon RV250 If [Radeon 9000] (rev 01)

    Shall I try with an older kernel ?

    yes, now compiz work
    i read somewhere that all effect are working on 9.04 PPC with KDE.
    So, I have just installed KDE on my Mac, and surprise,
    effect are working, so I went back to Gnome session and Big Surprise they are working too now

    Thanks a lot to everyone who helped and long life to Linux, Ubuntu and Free Software.




    Sorry, for my (too) bad english

    What configuration ended up working? Did you have to change any settings to get desktop effects working in KDE? (I'm running KDE and nothing would work until I edited xorg.conf.)

    I've got the same setup. Same problems too.
    I have done this stuff, and seen limited success.

    I have gone back to "None" effects because of frequent freezes while doing trivial things, like alt+tab application switching, using either "Normal" or "Extra." Has anyone come up with driver and xorg.conf settings that give acceptable performance?
