glxinfo setting to verbose mode outputs no extra info?

Hi,

 

I am using Debian Lenny on a PC. I am trying to figure out why direct rendering is not working so upon giving "glxinfo" command I get:

# glxinfo > glxinfo.txt

name of display: :0.0
display: :0  screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:

.............................

.............................

 

So I set:

# export LIBGL_DEBUG=verbose

 

and then gave the command again:

# glxinfo > glxinfo-debug.txt

 

However, setting to verbose mode did not produce any extra output:

# diff glxinfo.txt glxinfo-debug.txt

 

What did I do wrong?

 

Thanks
