Public bug reported:

After fresh install of  Ubuntu 14.10, I am experiencing a weird problem:

When I log out from Unity session (or any other desktop session) Lightdm
flashes twice (as if it reloads itself twice) & sets the brightness to
max.

I set following setiing to /etc/rc.local to preserve my brightness
settings.

echo 3 > /sys/class/backlight/acpi_video0/brightness
echo 2997708 > /sys/class/backlight/intel_backlight/brightness

 When I log in at boot it flashes but doesn't  alter brightness. The
problem occurs if I logout or restart lightdm manually from text-termial
(ctrl+alt+f1, sudo service lightdm restart). I have attached lightdm &
x-0 & x-o-greeter log files.

Output of "lshw -c video"
