Glxgears shows very poor performance with Ati Radeon 1300

EDIT: Also, before we continue, I suggest re-enabling KMS.

I saw that it was redhat package manager and I didn't realized because I just switched from Mandriva to Debian. :-)

The output is

libgl1-mesa-glx: /usr/lib/libGL.so.1.2

I will reenable kms and reboot now.

After re-enabling KMS it seems that the performance was improved.
Somehow, Xvideo now works good... last time, with KMS enabled the 'xvinfo' command showed "no adapters present".
But now it seems that the Open GL (Mesa) it's not working as before: the 'glxgears' command gives me a black square.

Show us the output of 'glxinfo | grep -i render' . And your /var/log/Xorg.0.log. This time, though, I suggest using a service like http://pastebin.com/ and just giving us the link.

DRI is ok:

glxinfo | grep -i render
direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on ATI RV515
GL_MESA_window_pos, GL_NV_blend_square, GL_NV_conditional_render

Well, your 3D drivers definitely appear to be installed properly. I'm honestly not sure why glxgears would give you a black window. Do other 3D applications do the same?

I guess I should investigate this further. It might be something related to the monitor: Compaq V70. I am trying to figure out how to setup all the drivers the right way.
I was quite used with a Redhat based distribution and harddrake :-)

Thanks, you helped a lot!
