So, when I suspend my laptop, then wake it up later, my laptop does turn on, I'm able to, for example, turn up and down the volume with audio confirmation using the kepboard, but my screen remains black and doesn't show anything until after I restart my laptop.
Ubuntu – 18.04 Screen remains blank after wake up from suspend

It is the buggy nouveau driver again. That's what solved the issue for me. Edit the file
/etc/default/grub
(using Vi editor -- some users have not been able to save after editing in Vi and have had to use the alternate "Ex" editing mode, which substitutessudo edit
below, then Alt+:w and :x for the save and exit commands).Add
nouveau.modeset=0
to the line that saysGRUB_CMDLINE_LINUX
then press CtrlO to save the file and CtrlX to leave Editor.Run
Now reboot.
