Hi
I've been trying to diagnose this for a while now and its actually been happening for months. Sometimes when it comes out of suspend it doesn't and needs a hard reset. Also, quite often it will freeze during a normal session, blank and then return to the Gnome login screen. I'm really not sure if the 2 issues are related but i do note common lines in /var/log/syslog and messages - an example is below.

this just happened again, now with libmutter-7

I'm at a loss how to report this as I don't think I have enough to suggest libmutter (do i?) and then there's the suspend issue. The last one of those from a couple of days ago i think i have isolated to the below:

I am totally stumped on where to look here or what might be at fault TBH. Suggestions appreciated.
