Closing the laptop lid suspends the system, opening it resumes it, but the screen is black. I’m guessing it’s related to powerup because suspending through the logout menu and systemctl suspend both work as expected. When it’s black, switching to a different tty works, as well as C-M-Backspace to logout.
Same results with both lightdm and sddm, when replacing suspend with hibernate, and I’ve tried a few solutions like disabling lock on sleep.
Seems like this issue has been around for years, but had a whole bunch of different causes since every other thread has a different solution.

Tried
systemctl suspendand then resume:dmesg after a successful resume

So it’s probably not a compatibility problem.
How is your swap sized compared to your system memory?
