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.
