Does GNU/Linux keep a log of when the machine and/or monitor was turned on?
I wish to limit my screen time by telling the machine to automatically hibernate 90 minutes after the last startup or awake. This precludes using
@reboot, I think, and I don't think
cron has an
@awake parameter. Currently,
systemctrl suspend runs every X minutes, even when the current session is is less than 90 minutes.
