Auto shutdown/startup script

[Zefty]

Not really an issue with LWSM as I am able to run the commands fine. I'm having some trouble getting an auto shutdown/startup script going. Would appreciate it if anyone has any solutions, cheers!

Im not very familiar with this application, but it seems that it is user based. If you are running this in a service, it is likely not running as the required user.

I think you would need a startup app (added to your session startup) and one for logout which I'm not sure how that would work. It would probably be easy enough to have a cron job running for the user to regularly save the session?

Im trying some of this out at the moment. Will let you know how I go.

[ Update ]
I dont think this will work as I expect. The program doesnt restore apps to correct positions or sizes and virtual screens. Much easier to have a manual hibernate. Im kind of puzzled why linux doesnt have a "snapshot" mechanism built into the system - essentially restoring the current memory layout for a session. Maybe I'll write one :)

I am also having issues creating a systemd service that saves the layout when suspending and restores it when resuming.

I am getting errors. Presumably because systemd does not have the environment variables set that my user has.

If somebody can make this work I'd be so happy :)

The zsh scripts themselves work from cli.
