I have a related issue that may be related to the problem. After logging out of my account the second time X crashes. This is very consistent it always happens the 2nd time I logout of KDE. Killing X from a VT, then switching back to the login with alt/ctl F7 locks up the display, mouse and keyboard. The only thing I can do is login from my laptop and do a (shutdown -r now) to fix it.
