FWIW, it's definitely recommended to use XVideo over OpenGL for video playback on Apple PPC laptops. > Anyway, with my current setup, I don't get any kind of OpenGL and I > have provided a "snapshot" of how things are configured in my system > at: > > > http://www.ime.usp.br/~rbrito/linux/debug-r300/1385003057-g4-linux-3.12-trunk-powerpc.tar.xz Looks like OpenGL is disabled due to the problem described in: https://lists.debian.org/debian-powerpc/2013/11/msg00045.html https://bugs.freedesktop.org/show_bug.cgi?id=71789 Someone will need to investigate this upstream in Mesa. > After struggling a lot, I could get mplayer/mpv/vlc to play some > videos if I force XV to be used as the video backend, but, with mpv, I > get the following message: > > [vo/xv] X11 can't keep up!

If your iBook isn't stable with the default AGP mode, try radeon.agpmode=1 or the other values. > Also, not really sure if things are connected to this graphics thing > or not, with Iceweasel 17, I can use things OK, but with Icewease 24, > I simply get a segfault right at the start.

Not necessarily WebGL, but it might be related to OpenGL, yes. One would need to look at a backtrace of a crash to tell though. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
