Comment 2 Erwann Chénedé 2008-04-15 07:35:57 UTC

The problem was that if the openGL libraries are not 
configured to use only indirect rendering the extension
GLX_EXT_texture_from_pixmap wouldn't be enabled with intel and 
ati drivers.
So instead of querying via glXQueryExtensionsString
I'm using glXQueryServerString to check only for the 
existence of the extension. 
This fixes the appearance applet bug. 

I've also modified the compiz startup script to 
add the additional env. variables to for indirect rendering.
