I left X running with xscreensaver for probably almost two days without a crash. Previous to that and after applying the option, I tried to use Linux, with ICEWM like I would normally, (surfing the web with Mozilla, reading news with pan, email etc.) and the system finally crashed after at least an hour. A little investigation, seemed to suggest that the crash happened in the glibc select call. (Mouse cursor would not move, display was frozen.). I had to log in remotely to shutdown.
Another problem I have, but still investigating is when I launch X using 'startx', log out of X, and then run startx again, X doesn't start and I get a blank terminal. I updated glibc to 2.2.5-4 and things seem better but I haven't banged on Linux really hard or checked if 'startx' problem has gone away. However, I did do 'normal' stuff without a crash, and shutdown Linux normally to boot to Mac OS X. Anyway this is a vast improvement nonetheless. Thanks Mark! > > > In the section device?
