Is there some sort of ultra deep sleep mode sddm goes into if it has been unused for a while? No power on earth seems to be able to get any signal to appear on my monitor after I have let the system sit for a long weekend.
Moving the mouse, tapping the spacebar, nothing works. I've had to ssh into the system and reboot to get it back twice now. Merely leaving it overnight is no problem, but leaving it for two or three days seems to render it unable to wake.

Presumably you tried 'systemctl status sddm' and 'strace -p <pid of sddm>'?

Not yet. I'm usually in a hurry to do something useful rather than spend time investigating :-), so I thought I'd ask here first.
I did look at the old Xorg log, and X was apparently running when I rebooted, and shut down normally on the reboot, no indication of any problem prior to the shutdown.

None of my systems experience what you're talking about.
3 of them are VM's which I mostly access via ssh. But when I do login graphically I've not had any problems. The other is a laptop that can sit for over a week without being used. I just move the touch-pad a bit and the login screen shows without delay.

I'd venture a guess that it's more likely the video driver locking up. Use "journalctl" to get the logs from one of the failed periods and see if there are any "kernel" log messages from that boot.

Nothing in the logs that appears to be nvidia related or any kind of kernel crash at all. I do see loads of errors from sddm every time it starts that look like something to do with loading the various theme files, but since I can login (when it isn't asleep), they don't appear to be critical.
