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
ldd /usr/bin/compiz
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
glxinfo output):

Hello,
I am trying to install and run compiz on my computer since a few
months yet and there is no way. Today I checked out the latest git
version and it does not work neither.
I have a ATI Radeon 7500 rev200 and I think thats the problem. I am
using the open source radeon driver and xorg with AIGLX (on debian
testing/unstable). DRI is enabled and working, glxgears, too. The
output of glxinfo is good, too.
Starting compiz I get this errors:
$ compiz --replace gconf &
libGL warning: 3D driver claims to not support visual 0x4b
compiz: GLX_EXT_texture_from_pixmap is not supported by direct
rendering context, trying indirect rendering context instead
compiz: GLX_EXT_texture_from_pixmap is missing
compiz: Failed to manage screen: 0
compiz: No manageable screens found on display :0.0
I get a Desktop environment without window manager and without any
window decorations. I can switch the focus, because I have "focus
follows mouse" but I can't bring windows to the foreground and I can
not move the windows.
I spent hours searching for this error messages and I tried all I
read. Running "LIBGL_ALWAYS_INDIRECT=TRUE compiz --replace gconf"
does eliminate the error message, but compiz is not working, same
result.
Does anybody know whats the problem with this error message? Where
can I start to search for more information? Are there any libraries
wrong? Is this an issue of the xorg radeon driver?
Thank you very much.
Regards,
Paul.
