    Re: Desktop Effects working in jaunty on ppc?

    I seem to remember those cards having problems with desktop affects back in the old driver days when using the default 24-bit color depth.

    Can you edit your /etc/X11/xorg.conf, and force it to 16-bits instead? This might be the tradeoff to get it to work if 16-bit color depth is usable for you.

    Ie, something like this:

    Code:
    Section "Screen"
            Identifier "Screen0"
            Device     "Card0"
            Monitor    "Monitor0"
            DefaultDepth 16
            SubSection "Display"
                    Viewport  0 0
                    Depth     16
                    Modes     "1024x768"
            EndSubSection
    EndSection

    I had the same issue with my mac mini 1.42Ghz/RV280, I tried the PCI workaround but with very limited success too (about 500 FPs but a very glitchy display).

    So I have upgraded the kernel to 2.6.29.3 (not so difficult, I never did it before and I did not face any issue, thanks to the very good tutorial found on this forum) and the problem disappeared.

    Now that's about 1250 FPs. I thought it should be better but that's enough for OpenGL screensavers, games and Compiz desktop effects.

    anybody have any idea when they're going to upload a new kernel deb file .. or maybe someone can post their own linux kernel .deb file? even with that PCI option in xorg.conf, my desktop feels so slow ...

    kernel 2.6.29.3 recompiled with my existing config file, no special optimizations.
