I've got a Dell Inspiron laptop that gets a blank screen after waking up from sleep, after updating to 5.5.5. Downgraded to 5.4.Apart from dumping the output of 'lspci -vnn' into Bugzilla, is there any troubleshooting I can do.Does the capslock light work? Can you switch to a text console using ctrl-alt-f3? Can you connect using ssh from another computer? After you reboot it, what are the first lines from: journalctl -b-1 -r
The laptop was still responsive, the three-fingered salute initiated a reboot. Looking through the journal logs, I don't see anything related to the display. Everything looks normal, the wireless comes up normally, and reconnnects to the wireless. The closest complaint I could see is something with the audio card:

The backlight was on, but the entire screen was black. ALT-Fn, to switch VTs, didn't elicit a response, but the three-fingered salute initiated a reboot. I haven't tried to ssh in, but given that, and the following in journal:
