The bug is still present for me in 16.04 as well. Dual monitor - ctrl-alt-l or turn screen off when inactive do not turn off the screen.
The workaround suggested from fugounashi works i.e., xset dpms force off but it is not permanent. The problem will come back after a while. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/1292041 Title: Lockscreen doesn't turn off the screen Status in OEM Priority Project: Fix Released Status in OEM Priority Project trusty series: Fix Released Status in Unity: Fix Released Status in gnome-screensaver package in Ubuntu: Invalid Status in unity package in Ubuntu: Fix Released Bug description: [ATTENTION] This bug report is strictly for lockscreen. When user activates lockscreen with Ctrl+Alt+L or Super+L shortcut or from indicator-session the screen should blank off after a couple seconds. The new Unity lock screen doesn't turn off the monitor screen. I can wait as long as 10 minutes after activating the lock screen and the monitor still doesn't turn off. Then when I unlock the screen and don't use mouse or keyboard monitor will turn off (it's about 5 seconds after unlocking).
