Public bug reported:
This problem happens after all hibernation, not instantly after wake up but
after a bit of usage, generally when triggering some animation of the DE. My
laptop is a inspiron 7000, with a gtx 1050ti, intel i7 7000, ubuntu 18.04.4
LTS.
I would be happy if anyone could tell me of any workaround too because
after freezing killall -9 Xorg doesn't do much and any other attempt to
restart Xorg. During this freeze switching tty also doesn't work. Audio,
network ( i could ssh to the machine), everything else is still running.
