The 8.14.13 ebuild didn't copy atiogl_a_dri.so into /usr/X11R6/lib/modules/dri/. This file is part of the original rpm released by ATI and is vital for DRI to work with the fglrx driver: $ LIBGL_DEBUG=verbose fglrxinfo libGL: XF86DRIGetClientDriverName: 8.14.13 atiogl_a (screen 0) libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/atiogl_a_dri.so libGL error: dlopen /usr/X11R6/lib/modules/dri/atiogl_a_dri.so failed (/usr/X11R6/lib/modules/dri/atiogl_a_dri.so: cannot open shared object file: No such file or directory) libGL error: unable to find driver: atiogl_a_dri.so libGL: XF86DRIGetClientDriverName: 8.14.13 atiogl_a (screen 0) libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/atiogl_a_dri.so libGL error: dlopen /usr/X11R6/lib/modules/dri/atiogl_a_dri.so failed (/usr/X11R6/lib/modules/dri/atiogl_a_dri.so: cannot open shared object file: No such file or directory) libGL error: unable to find driver: atiogl_a_dri.so display: :0.0 screen: 0 OpenGL vendor string: Mesa project: www.mesa3d.org OpenGL renderer string: Mesa GLX Indirect OpenGL version string: 1.2 (1.5 Mesa 6.2.1) Without the file OpenGL applications will not work or use indirect rendering. Extracting the file from the ATI rpm and placing it in the appropriate directory fixes the problem (restart of Xorg results in opengl applications working perfectly as before).
Found the problem in the ebuild. Hopefully fixed, reopen if isn't.
Yes it's fixed ... is it me or you gentoo ppl that are supposed to verify, close or whatever this bug now?
