Public bug reported:
So I upgraded both my laptop and my desktop 12:th Nov. Been using it
happily and without issues for almost two days.
Yesterday late evening (13th) before going to sleep I wake my desktop using
mouse movement.
LockScreen appears do the upwards drag gesture (which is a bit annoying) and
when the curtain rises all i get is a glitchy side-dock and a blank purple
gradient.
The side-dock weirdly enough shows the previews of applications when hovering
the app-icons, but interacting with it using click doesn't bring the
application-windows up.
So I go to bed thinking i'll fix this tomorrow..
Wake up, move the mouse on desktop-pc, screen turns on and it's still
the same glitched desktop view.
So I pick up my laptop and surprisingly enough I have Exactly the same problem
there!
With the exception that instead of the screen being blank I see some kind of
malformed version of the applications I had running last evening.
Both computers failed at resuming from screen-lock, so I reboot both of them.
Laptop is working for now (That's how i'm filing this bug).
But desktop computer went into screen blank due to inactivity and froze again
when i tried to wake it up.
I never had this issue before 18.10, and I suspect that some bad auto-
update went out yesterday since both of computers mysteriously started
failing around the same time.
