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
---
