There is common issue with the r300 driver in Mesa and Radeon cards on G4
Macs. When you have KMS enabled and to see if useing opengl you get this.

rican-linux@ibookG4-gentoo ~ $ LIBGL_DEBUG=verbose glxinfo |grep render
libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 1002:4e56, driver r300
libGL: OpenDriver: trying /usr/lib/dri/tls/r300_dri.so
libGL: OpenDriver: trying /usr/lib/dri/r300_dri.so
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: r300
libGL: OpenDriver: trying /usr/lib/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Error: couldn't find RGB GLX visual or fbconfig


There are two ways to resolve this

1. set you default display to 16 in xorg.conf, but on PowerBook you really
see the drop in depth bot so much in iBooks.

2. apply a patch found here
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746272>

I would much rather do option 2 and test that, however I am having some
difficulty learning how to apply patches and reinstall in gentoo. In debian
or ubuntu i would apt-get source the package, apply the patch, then
recompile and reinstall. Can someone point me to resource that can help. I
really cannot find it in the gentoo wiki, but I admit it may be I am not
search for the correct thing. Thanks!

You create local overlay, copy ebuilds you want to change from main portage tree to you overlay, modify ebuild (e.g. add patch), then execute `ebuild filename.ebuild digest`. After that you emerge the same package name as before and it gets installed from your overlay.

Research on how to create a local overlay on the gentoo site. Will attempt
when I get home. Thanks

I have succesfully applied and installed mesa with the patch.
I needed to do the following

move the ebuild to my overlay /usr/local/portage/media-libs/mesa

then run the follwoing commands
ebuild pathtoebuild digest
ebuild pathtoebuils fetch
ebuild pathtoebuild unpack
then manuall apply patches
ebuild pathtoebuils compile
ebuild pathtoebuild install

how ever I an still not getting 3D. The only difference I am seeing is that
in Debian i needed to install linux-frimware-nonfree and I do not have that
option in gentoo.

It looks like to 3D working with the r300 driver you need set the default
display to 16 in Xorg on gentoo.

rican-linux@ibookG4-gentoo ~ $ LIBGL_DEBUG=verbose glxinfo |grep render
libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 1002:4e56, driver r300
libGL: OpenDriver: trying /usr/lib/dri/tls/r300_dri.so
libGL: OpenDriver: trying /usr/lib/dri/r300_dri.so
direct rendering: Yes
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
    GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
OpenGL renderer string: Gallium 0.4 on ATI RV350
    GL_MESA_ycbcr_texture, GL_NV_blend_square, GL_NV_conditional_render,
    GL_OES_element_index_uint, GL_OES_fbo_render_mipmap,

I remember similar thing with i810 video on x86 - with 24-bit depth I had only indirect rendering (because of lacking video RAM), while with 16 I had direct rendering.

Yeah I just wish those patch would have worked. I used them on Debian and I got direct rendering without going to 16. I am pretty sure I am not doing something right.
