Is there any way to do that on Plasma? I have an issue where my shutdown and reboot is delayed by many seconds because, the system is synching. I would like to prepend the sync command to the actual shutdown command spawned from the menu. Is it possible?

I have a similar issue, please read my posts... Unfortunately nobody has a clue...not even the KDE developers...

But you could write your own shutdown scripts with poweroff or shutdown commands and remove that KDE power/session b u l l s h i t

There is also a nice app called qshutdown for Debian!

You can block/delay shutdown (idle, sleep) using systemd-inhibit. That is what Plasma does itself (see `systemd-inhibit --list``)

Simple example to block idling:

Code: Select all

systemd-inhibit --who me --why because --what idle --mode block bash


As long as this bash session runs (exit with ctrl-d) the system won't idle, preventing all screensaver, power management stuff, etc. from doing their jobs. As soon as the last filedescriptor is released (in this case, bash is exited) the block is removed.
