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.
Yes, you need enough swap to fit all your RAM’s content to successfully hibernate/hybrid sleep. In the case of regular suspend to ram this shouldn’t happen though
I have a feeling my swappiness setting was already aggressively paging, so I already had no space. I also turned my swappiness way down.
