You could try to ping your machine from another device and see if it responds. I had issues with older nvidia card on a old system where it would lock up keyboard/mouse and video but the underlying system was still running and I could ssh into the machine and debug the problem that way. Another computer is obviously preferred but in a pinch a cellphone is better than nothing.
I actually did something for quite a while. Finished long overdue wiring for outdoor access point and one more camera, replaced a main switch since the old one started to behave unreliably, installed frigate (which still needs some work), cleaned up some wiring while messing around, updated a bunch of firmwares, replaced switch in garage to managed one and made some changes on my workstation and some other minor stuff.
Next would be to move cameras into their own VLAN and harden that setup a bit. And I really should get around on better backups for my VPS. But it’s a new week coming up, if the work isn’t too busy I might get something more done.
