!!! I just learned about this recently because my PC has an Nvidia GPU and it sometimes waked up from sleeping to a blank screen with just the mouse cursor showing. I have try that REISUB first but if that doesn’t do anything, I have to go to Ctrl-Alt-F3 and do “sudo reboot”.
I once kept opening new terminal sessions then launching a fresh X session while doing something that had a tendency to crash X. I ended up with about 3 crashed graphical sessions by the time I finished what I was doing and actually rebooted!
You should really use the reboot command first because you don’t have to control the order and timing. REISU(B/O) requires pauses between letters for the specific action to run. It also requires those letters to be in that particular order - you can’t sync the file system if you put it into read only. If REISUB is sometimes not working but you can go elsewhere and reboot, you’re likely not doing it right and you should err on the side of caution and use the reboot command
reisub is not “safe”. it is the “safest” way when your system has reached an otherwise broken state, but you’re still interrupting things that may be saving state or changing configurations. if your system is working behind the scenes you may very well break it more.
REISUB
Raising Elephants Is So Utterly Boring

Linux is fun except for when it’s not.

I’m confused. Why would you REISUB/O if you can use the reboot command?
REISUB is a last resort before hitting the physical power button
Haha, because I’m lazy and going with the fastest, safe way to reboot when I get stuck.

Gotcha, thanks;

You probably have to enable it in sysctl
