I'm running both Unity and Cinnamon in 14.04 with lightdm. That way unity-greeter takes over on logout from both. To get display power off to work on my desktop I added (username) and root to lightwm in the /etc/group file.
lightdm:x:111:(username),root Then I added the executable script /usr/bin/dpms-start : #!/bin/sh # /usr/bin/xset +dpms exit In the /usr/share/lightdm/lightdm.conf.d/ directory I added the 50-dpms.conf file : [SeatDefaults] display-setup-script=/usr/bin/dpms-start A bash script may also work by changing the user to lightdm before executing "/usr/bin/dpms-start" : sudo xhost +SI:localuser:lightdm sudo su lightdm -s /bin/bash <<HERE /usr/bin/dpms-start exit HERE You then don't have to modify the /etc/group file. Hope this works for others still having trouble. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
