I confirm it has been solved for me as well.

I indeed did the same things reported by Peter, so the cause could have been
the same.

I found the cause - it was caused by my change :O of
/etc/X11/xorg.conf.d/20-intel.conf.

The problem was

Option "AccelMethod" "uxa"

and when I changed it back to

Option "AccelMethod" "sna"

it started to work again.
The reason I changed this configuration was an attempt to play with with hw
acceleration in Firefox which btw did not help.

This also happened to me few times but when I tried to reproduce it, I was not
successful.
Due to my main problem in bug 381515 I do have kscreen.log so when it occurs
again I will attach my kscreen.log here.
