GL failure in iBook G4
Hello,
while on my PowerBook OpenGL works (both in a browser as well in minimal
test case glxgears) on my iBook G4 not:
$ glxgears
radeon: Invalid PCI ID.
libGL error: glx: failed to create dri2 screen
libGL error: failed to load driver: radeonsi
LLVM ERROR: Relocation type not implemented yet!
Aborted
the iBook G4 has a slightly minor ATI card:
