Screen does not lock or turn off automatically

[Rocko]

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).

Other users are reporting the same issue: see http://ubuntuforums.org/showthread.php?t=2246601&highlight=turn.

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...

In my case this was a new 14.10 installation from the daily ISO of 2014.09.16. It was todays updates that created this issue, but the last update I did was September 30th.

same here, screen never shuts off no matter what i set it to in "brightness and lock".

daily fresh installed about a week ago. 64bit ubuntu with nvidia graphics.

Can confirm, fresh install here, not upgrade - same issue. Same issue with default mesa and mesa git from Oibaf PPA, so it's not that I suppose (I'm on AMD).

I'm seeing this in the two systems I upgraded to 14.10, both with NVIDIA cards, different models.

I believe this is a duplicate of bug #1377847.
