Public bug reported:
I am running Kubuntu 18.04, fully updated with the 5.0 kernel, on a Dell
XPS13 9360. I tend to put the laptop to sleep by closing the lid when
not using it. It will also automatically sleep after 10 idle minutes
when on battery. Basically the default Plasma power settings.
Mostly the laptop will sleep and resume no problem, but fairly
frequently (perhaps once every couple of days) it will freeze with a
blank screen (sometimes with just the pointer visible) and the power
light on. This can happen when sleeping after being idle for 10 minutes,
or when the lid is closed. Also sometimes it will not sleep when the lid
is closed, meaning when I later open the lid the laptop still responds
but has a drained battery.
I can trigger this manually by selecting 'suspend from the KDE 'leave'
menu. This resulted in a blank screen with just the cursor displayed and
the whole machine locked-up. So this is fairly reliably reproducible.
I have installed kernel 5.3-rc6 and initial tests are proving positive.
I have just done about 15 suspends in a row. No lockups and the majority
of the suspends resulted in a suspended laptop. A few however - say
every 4-5 attempts - resulted in the laptop just going straight back to
the lock screen, almost as if it had suspended and immediately resumed
again. So it looks like my immediate problem (i.e. the lock-ups) have
been solved. Can this be investigate however in the 5.0.0.25 kernel?
Thanks
Nick
