Unity won't suspend on inactivity

rated 0 times [ 1] [ 0] / answers: 1 / hits: 5023 / 2 Years ago, sat, february 26, 2022, 7:46:09

Running 12.04. I can manually suspend the system and wake it up again, but I can't get it to suspend on inactivity automatically.

I have it set to "Suspend when inactive for" 10 minutes in systems settings > power. It just blanks the screen, but does not suspend.

Info as requested. Left system untouched at 18:30 with suspend set to 10 minutes.

kern.log and dmesg had nothing new in them.

sys.log had these extra lines

Aug 23 18:34:26 Ubuntu-desktop AptDaemon: INFO: Quitting due to inactivity

Aug 23 18:34:26 Ubuntu-desktop AptDaemon: INFO: Quitting was requested

Aug 23 18:39:01 Ubuntu-desktop CRON[3228]: (root) CMD (  [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir fuser -s {} 2>/dev/null ; -delete)

Well, I finally managed to get it to suspend fully on inactivity.

In addition to System Settings > Power set to turn off after 10 minutes, I had to ALSO set System Settings > Brightness and Lock to turn off the screen after 10 minutes.

Surely if these 2 settings are dependent on each other they should be together in one section of System Settings? The way they interact seems wrong, and the Systems Settings > Power section doesn't hint or warn that it can't be set independently.
