Are you using an nvidia video card with the binary drivers? This happens to me sometimes, and I suspect the video drivers. When I ssh/telnet into the "hung" box, X is taking up 100% of cpu. If I do this everything starts to work again: --- killall X [just to be sure] killall -9 X init 3 [wait 5 secs] init 5 ---
