Follow-up from "Dumbest Thing you have done distro-hopping?".
Here's mine - the laptop from which I'm typing right now has a broken touchpad that keeps jumping and clicking randomly, and does not work. Well, I can't afford to fix it, but at the moment, I was so pissed off I punched the touchpad really hard, and the machine panicked with all the lights blinking. A few more revival abuses, and the machine was back to life, but since I was running a nixos-rebuild switch --upgrade in the background, I blew off my boot partition. I think I just broke the unbreakable distro.
I had a slightly screwed up Fedora install due to being a noob with an NVIDIA 1060 and little clue on their drivers. I hooked my laptop up to an old TV (720p if that tells you how old it is lol) and... my entire desktop got absolutely screwed up. Everything was stuck in 4:3 resolution for some reason and my icons got bloated (for lack of a better term). I tried to fix it but IIRC, it just got worse and I had to reinstall.
