I have the exact same problem as he mentioned above...initially, i upgraded from 14.04 to 14.10 ...I am also using unity... Then i tried doing a clean install and the same thing happens (so obviously it nothing to do with the upgrading factor)....
After the clean install, it initially worked fine...but once i did all the updates, the problem was there again, so it seems like it something caused this in the most recent updates (last few days)... No matter what you set it for, in the "brightness and lock" section of system settings, the screen will not turn off and go to black. Also having the same problem with lock as the previous report mentioned... I am running 64 bit version on a laptop with intel graphics and the standard driver... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1377537 Title: Screen does not lock or turn off automatically Status in “unity” package in Ubuntu: Confirmed Bug description: In Ubuntu 14.10 (upgraded from 14.04), the screen does not lock or turn off after the designated time in System Settings / Brightness and Lock. The screen lock can still be activated manually from the System menu or keyboard shortcut (although I notice that the default has changed from CTRL-ALT-DEL to Super-L, and if I change this back in the System Settings / Keyboard / Shortcuts, both combinations work - it seems that the unity plugin in compiz (CCSM / unity / general) has aother screen lock key short cut).
