What do I do, when my PC freezes?
Windows has ctrl+alt+del, does Linux Mint has something comparable? The only thing I know about is REISUB, but that borked my PC, so I am hesitant to use that again.
Are there any remaining alternatives to waiting and/or using the power button?
Edit: Thank you all for your insights and possible fixes. Crashes usually happened when I was running (cpu/ram?) heavy workload. Increasing swap space was not even on my radar, so I did that now. :) Hopefully Mint will run more stable now.
Since crashes usually happened under heavy workload (I guess CPU/RAM heavy stuff) and I didn’t pay attention to swap space before, I think this was the most likely cause. I increased it and will have to wait and see if it helps. If not, I’ll consult your comment here :)
