The keyboard shortcut Ctrl + Alt + PrtScn + o worked on Ubuntu 20.04, but it doesn't work with my current installation of Ubuntu 21.10, gnome: 40.4. This keyboard shortcut should shut down the computer instead of pressing the hardware power button for 4 seconds if necessary.

your link helped me for the current session: {{{ sudo sysctl -w kernel.sysrq=1 }}} But I would prefer to have the possibilty after every boot.
If I try {{{ sudo vi /proc/sys/kernel/sysrq }}} there is only one line with the entry "16". I diddn't manage it to save it with value "1": {{{ "/proc/sys/kernel/sysrq" E667: Fsync fehlgeschlagen Betätigen Sie die EINGABETASTE oder geben Sie einen Befehl ein }}} I can't save it.
Nevertheless, I wonder why this option has been intentionally changed?
