I've done some more tests with another clean install of 19.04; The only user setting I changed was on x-p-m for Laptop Lid Closed, On Battery = suspend.
1st suspend=resume cycle is fine; user session re-appears after unlocking with password *BUT* 2nd suspend-resume cycle turns the LCD panel off after unlocking with password (greeter with password dialog is show, LCD is turned off as soon as session is unlocked. This is repeatable via using a TTY to "sudo systemctl restart lightdm" So it seems as if there's some runtime option getting mixed up here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759950 Title: Lid-close suspend: blank screen when switching to user session To manage notifications about this bug go to: https://bugs.launchpad.net/light-locker/+bug/1759950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
