I've recently compiled xorg, mesa and drm for my rv250 and I've faced
few problems that I managed to solve. Since you have an rv200 (radeon
7500), you should be using the radeon_dri.so. I don't have any
experience with that driver but should be in good shape.
see if AIGLX is enabled:
grep AIGLX /var/log/Xorg.0.log
check what libraries compiz is using
particularly see for the libGL.so.1. Is it the one you are expecting?
when you used LIBGL_ALWAYS_INDIRECT=TRUE, you said the error message
disappears but compiz didn't work. Did it produce any other error message ?
are you using SELinux? if yes open the selinux-troubleshooter and see if
there are any warnings for the radeon_dri.so or libGL.so.1
you might want to see the end of this topic on the GLX_EXT_tfp extension
as well (basically see if the extension appears in all 3 sections of the
hope this helps
