Thinkpad Freezing (Re: [ltp] Odd apm issue)

[Douglas Bridges]

On my A2m, the machine was locking up in X after I left it sitting for a 
while. It wasn't the screensaver that was killing me; it was the X screen 
blanking. Since I disabled the screen blanking, I haven't had any problems. 
XScreensaver still works great.
