[Philipp Bliedung]

Hi,

How can I activate hardware acceleration for my GeForce2Go Grafikkarte  
-- Dell Inspiron 8100 ??

When I try to start Americas Army (www.americasarmy.com) i get this 
error message:

~/programs/armyops$ ./armyops
GL_EXT_bgra not supported - bailing out.
History:
Exiting due to error

I am running Debian woody with backports for Gnome 2.4 and KDE 3.1 ...
(NVidia driver: 1.0-4363)

How can I activate GL_EXT_bgra support ??

glxinfo gives me this:
