Still broken with MATE desktop on Ubuntu 18.04.2 LTS. If I run mate- power-preferences and select ON AC Power - Put computer to sleep when inactive for: [never] the computer still automatically sleeps (enters S3) after 20 minutes.
$ grep -C1 sleep-inactive-ac-timeout /usr/share/glib-2.0/schemas/10_ubuntu-settings.gschema.override [org.gnome.settings-daemon.plugins.power] sleep-inactive-ac-timeout = 0 I've tried to manually run $ systemd-inhibit --mode=block sleep 2h but the system still enters S3 after 20 minutes unless I disable screen saver using mate-inhibit-applet. $ apt policy mate-desktop mate-desktop: Installed: 1.20.1-2ubuntu1 Candidate: 1.20.1-2ubuntu1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759008 Title: Revert automatic suspend by default for bionic?
