You have been subscribed to a public bug:
This problem's first symptom is that you are completely logged out of
your X session as soon as you try to run something like Tuxpaint on PPC.
I have seen it on Fedora, Debian Lenny and Intrepid. Etch worked fine,
probably because directfb was version 0.9.
I have stepped though Tuxpaint until an SDL init:
SDL_Init(1048625)
(Those flags are: SDL_INIT_VIDEO | SDL_INIT_TIMER | SDL_INIT_AUDO |
SDL_INIT_NOPARACHUTE)
I then stepped through the SDL code until here:
DirectFB_CreateDevice (devindex=<value optimized out>) at
../../src/video/directfb/SDL_DirectFB_video.c:123
DirectFB_CreateDevice crashes. It sometimes prints the error below, but mostly
it doesn't print anything, it just terminates the session. Since it looks
permissions related I have
run everything as root but that doesn't help.
