--- Comment #2 from adriano neustadt@gmx-topmail.de 2007-11-09 05:14:02 --- well yes, thanks
glxgears did crash. it was a kernel problem (strangely, because i didnt recall messing around with my kernel at all)
anyways, i recompiled my kernel and all the modules and everything works like a charm again.
