Public bug reported:

It is a  Lenovo G50-45 laptop with AMD/ATI Radeon APU A4-6000 with R2
Graphics.

When I boot up Ubuntu 14.04.1 64 bit using fglrx (or fglrx-updates)
2:13.350.1-0ubuntu2, the screen gets very dim  at LightDM and remains
dim in Ubuntu desktop until I press one of the two brightness keys or
change brightness in System Settings.

Even though the screen is dim, the brightness slider in System Settings
or the brightness on-screen display shows that brightness is set at the
maximum.

It does not matter whether I increase or decrease brightness with the
function keys or the slider in System Settings, the screen will
immediately brighten up after touching the brightness keys or the System
Settings slider.

No improvement with fglrx 14.100-0ubuntu1 built with ubuntu-amd-
catalyst-install 3.9 either.

** Affects: fglrx-installer (Ubuntu)
     Importance: Undecided
         Status: New

** Package changed: webapps-applications (Ubuntu) => fglrx-installer
(Ubuntu)
