Re: 8756 for x86_64
Hmm I didn't notice your system hangs when you type glxinfo. That's not good. Have you tried installing under kernel 2.6.17? I would also re-install that glxinfo package. On my system it's called glx-utils. And try another monitor, eg. maybe a good time to upgrade to a flat screen.
Arrrgh, I've been using linux for years and just now found out you can change screen resolutions by pressinc CTRL-ALT+ (and minus). That would have been handy back when I was getting this other monitor working.
