Quite often (at this moment, I have even problems to finish this bug report,
but normally it was just around five times daily) the screen gets black. All
programs run (e.g., YouTube in Firefox is still playing), but I haven't found a
way how to get screen reinitialized (Ctrl-Alt-F2 and similar do nothing).

I observe this phenomenon for the last month or a little bit more, and it seems
to be changing with upcoming upgrades of some packages. I would guess kernel,
but I am not sure.

Currently the situation is pretty bad (openSUSE Tumbleweed kernel
4.18.0-rc7-1.g68c9705-default), and it is somehow erratic. Once this happens,
the computer tends to lock up all the time. Next day, computer is happy again
until the first freeze happens again.
