This bug needs to be reopened. I'm using a freshly installed and updated Ubuntu 16.04.4, with a laptop and an external monitor.
When the Brightness & Lock timeout occurs, my monitors do go off at first, but my laptop's built-in monitor wakes backup up permanently to the ubuntu login screen. I'm worried that it is going to eventually ruin my monitor. Due to this bug, I'm going to have to create a cron job to run this command routinely: xset dpms forceoff Please mark this bug as NOT FIXED! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1292041 Title: Lockscreen doesn't turn off the screen To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1292041/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
