[Problem]
X locks up in various circumstances, most easily reproduced when typing quickly into KMail's subject field.

[Original Report]
Since I ugpraded to Jaunty Beta, I experience common "lock-up".

When the display is "locked-up", the mouse pointer moves on the screen, but the pointer doesn't change, the keyboard doesn't do anything, and the display doesn't get any update.

I can SSH in the box and kill -9 the Xorg server. After that either nothing happens, or the screen becomes black. In all cases, the display is still non-functional. A shutdown -r usually doesn't complete either and I have to power-cycle the laptop.

This happen in various circumstances, but the most "reliable" way to trigger it is by creating a new email in Kmail and typing in the subject field very fast. It also happened in various other situations: like opening a new tab in firefox, starting up gvim, or just on my first log-in after the upgrade.

Btw, it seems that the KMail trick is a very reliable way to reproduce the lock-up. I've also found a "work-around" for this very common source of lock ups, i paste the subject line from another place, that way there is a single update to the window title which seems to be related to the problem.
