I have a newish laptop, only about one year old, that’s dual-booting NixOS and Windows. For some reason, on NixOS, it will routinely freeze, becoming unresponsive to keyboard, touchpad, touch screen, and everything. The mouse pointer stops moving. I also can’t do Ctrl+Alt+F1 to switch to a TTY. The only thing I can do is hard-poweroff my system by holding down the power button for ten seconds. This can’t be good.
It seems to happen a few times a day, at random times. That is, not only while I’m doing something compute-intensive.
I don’t think it could be the HD failing, since I just upgraded the SSD to a new one recently. (And this was happening before the upgrade, too.) I also don’t think it can be overheating, since this seems to happen when the computer’s cold, too.
I’ve tried looking through my log files, using the Log File Viewer, but I don’t see anything relevant, as far as I can tell. Maybe I don’t know what to look for, or am looking in the wrong files?
