This can be reproduced by setting screen brightness to a minimum and
turning off the screen. Also happens on auto brightness and when being
in a dark place.
Seems the minimum supplied power for the display needs to be increased
for tiny bit.

Bug description:
ubuntu 15.04 for phones beta r.223 (bq aquaris ubuntu edition)
Since r.222 upgrade i noticed that sometimes I cant unlock the phone.
When i push unlock button (one time) looks like nothing happens, screen
doesn't woke up.
If i press a second time screen woke up for half second showing unlock
screen.
When it happens, i know that the OS is running because when i push the
unlock button(first time), i can make a screen shot pushing up volume
and down volume at same time it also reproduce the sound.
Looks that the only problem is to wakeup the screen.
It began to happen without install any program, just upgrades.
When it happened to me I think that I haven't opened any app.
