better.

As per https://wiki.ubuntu.com/Releases, Ubuntu Intrepid reached EOL on

Title:
  All SDL apps crash in DirectFB on PPC

Status in xorg package in Ubuntu:
  Incomplete
Status in xserver-xorg-video-ati package in Debian:
  Fix Released

Bug description:
  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.
