I made a quick test in my recent Xubuntu (16.10, light-locker-command 1.7.0).
$ light-locker-command -V light-locker-command 1.7.0 $ light-locker-command --lock Both monitors switches off, as they should be. (A waited a bit, though not very much.) When resuming, after typing the password, the "unused" monitor goes back to off (backlight off too) state, as it should be. Similar results for suspending. So the bug does not seem to appear. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1520970 Title: light-locker switches disabled screen on (when used with xfce) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/light-locker/+bug/1520970/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
