compiz - Apr 2007 - ATI and GLX_EXT_texture_from_pixmap error

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.

Hi Denis,

Thank you for your answer.

The result is the same as described above. I have no window decorations 
and no working window manager at all.
> I also have radeon 7500, wokred well except blur (doesn't working)
Well, then it must work. It must be possible to localize the problem.

Regards
Paul.

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):

hope this helps
