I don't go much to the offending tab in Settings, but to avoid ending up with no autolock if I happen to click there, I added a crontab to set the idle-delay key once a day (at 17:30).
$ crontab -e 30 17 * * * XDG_RUNTIME_DIR=/run/user/1000 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus gsettings set org.gnome.desktop.session idle-delay 1800 These two variables are necessary, the set instruction wasn't working without it. I hardcoded my user ID (1000) since I'm the only user on this computer but the ID can be dynamically obtained (see https://stackoverflow.com/a/78894306/3715151). ** Summary changed: - Screen Blank delay (idle-delay) is set to 0 (zero) by clicking Privacy & Security tab in Settings + Screen Blank delay (idle-delay) is set to zero (uint32 0) on clicking Privacy & Security tab in Settings -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2083869 Title: Screen Blank delay (idle-delay) is set to zero (uint32 0) on clicking Privacy & Security tab in Settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/2083869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
