Squeeze remote X11 and GL

[Brian Sutherland <rmaniac@gmail.com>]

I have done some searching and can't seem to find an answer anywhere. 
This worked fine on Lenny and it is testing ok with Ubuntu Natty. If I 
am running squeeze be it native or in a chroot, ppc or i386, I can get 
applications to xhost from it but not opengl applications. So loading 
xterm pops up an xterm on the remote or main display (in chroot) but 
does this:
(squeeze)root@Grackle:~# glxinfo
name of display: :0.0

and nothing till I kill it

glxgears does not print anything and just sits till I kill it.

Like I said other distros on other machines or chroots are fine. It's 
just squeeze that won't do it, I have not tried wheezy.

Thanks!
