[PD] GEM - nvidia GeForce 6150SE with nvidia proprietary driver and ubuntu 8.10 hangs for number of seconds

[John Harrison]

for some reason the hanging doesn't happen as often when using compiz as 
opposed to metacity. I can live with this as long as I can be sure that 
when operating in fullscreen mode for several hours at the performance I 
am not going to have any hanging. My casual observations make me 
optimistic but if anybody has seen it hang while in fullscreen mode 
please let me know immediately so I can find an alternative solution for 
the gig on Fri.
