[Bug 1448535] [NEW] Lockscreen timeout un-blanks the screen

 

Public bug reported:

Just to separate the variables, use a different "Turn screen off when
inactive for" time and "Lock screen after" time under "Brightness and
Lock" under "System Setting".

Leave the system inactive. 
The screen goes blank after the appropriate inactive period.
After the additional screen lock time (or immediately if it is set to "When Screen turns off"), the screen turns back on and stays on, forever.
However, just move the mouse and then the screen will blank after the appropriate  inactive period, and this time, and subsequent times, it will stay off.
Now, unlock the computer, and this whole sequence will repeat.

I'm told this is not the same as bug 1292041 ,but I think it is related.
Why? Because this issue started the same day as that bug, namely
2014.03.12 (March 12th 2014).

This issue is repeatable on: Ubuntu desktop 14.04; Ubuntu desktop 15.04,
as upgraded from previous; Ubuntu desktop 15.04, as newly installed,
albeit during development.

This issue does not occur with Ubuntu desktop 12.04. And did not occur
with desktop 14.04 development prior to 2014.03.12.

Note: All of my work is with Virtual Computer guests on an Ubuntu server
14.04 host.
