I opened a PDF in Okular 0.12 (a single page text document), and
selected the text. As soon as I did this, KDE4.6.0 started doing odd
things. Apps stopped responding to mouse clicks, the KDE4 desktop
stopped responding (eg clicking the KMenu or any app in the taskbar
did nothing). I could switch apps using Alt+Tab, but the apps did
not respond to mouse clicks.
I switched over to tty1 and logged in as root. Attempts to kill
Okular (using kill -9) didn't help. Okular wouldn't die.... same with
trying to kill any other open app from CLI... they never changed
state, and never exited.
I then killed X by pressing Ctrl+Alt+Backspace twice. This seemed to
work, but KDM did not relaunch and put me in the login screen. At
tty1 I attempted to do an init3, and this failed with a KDM not
responding error.
Last resort, I typed reboot and hit enter. The system message "The
system is going down for reboot NOW" was shown... but the reboot never
happened. I ended up having to do a hard reset to get back up and
running.
So... I probably could have troubleshot this a lot better, but...
these are the basic steps I did up to the hard reset.
Checking the /var/log/messages file, there is nothing there that gives
me any clue what happened....

Anyone encounter something like this before? Any tips on where else I
can look to figure out what went wrong?
