I've been seeing this problem several times a day. I can't reproduce it in any
reliable way and I have no idea how I can go about collecting the needed info... Anyway,
here is what happens.
My most recent experience with "freeze" is not a solid one. The screen is frozen
but I can still move the mouse around. Also, if there is a video playing it will freeze
but the audio will continue on. I can get out of it by logging in from a terminal and
doing a "killall -u myusername" which gets me back to the login screen.
I think "kwin" is the most likely suspect and have upgraded to kwin-5.4.0-4 from
updates testing as the changelog included this nugget which gave me hope....
* Tue Aug 25 2015 Daniel Vrátil <dvratil(a)redhat.com> - 5.4.0-2
- add upstream patch to fix crash
- make sure kwayland-integration is installed for kwin-wayland
But no... Still have issues. Any suggestion on what to look for to see if the culprit can
be identified?
