$ compiz
Checking for Xgl: not present. 
Detected PCI ID for VGA: 01:05.0 0300: 1002:4337 (prog-if 00 [VGA])
Checking for texture_from_pixmap: not present. 
Trying again with indirect rendering:
Checking for texture_from_pixmap: present. 
Checking for non power of two support: present. 
Checking for Composite extension: present. 
Comparing resolution (1024x768) to maximum 3D texture size (512): Failed.
aborting and using fallback: /usr/bin/metacity 

It's strange because before maximum 3D texture size is 1024...

So i modify /usr/bin/compiz :
        TEXTURE_LIMIT=1024
        #TEXTURE_LIMIT=$(glxinfo -l | grep GL_MAX_TEXTURE_SIZE | sed 
's/.*=[^0-9]//g')

and now :
$ compiz 
Checking for Xgl: not present.

It works but when the window is maximized, the title bar is totally
white.

Before I didn't have this problem...
