[Launchpad Bug Tracker <850749@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

Once my laptop screen is dimmed I can not read it any more. Dimming
happens even when "dim" is not selected in the "screen" settings. It
also happens before logging in. There is nothing I can do to un-dim the
screen (i.e. moving the mouse, keyboard, but also using the
contrast/brightness keys). When the screen is not dimmed, it is possible
to adjust brightness etc using the contrast/brightness keys.

If the laptop is suspended/resumed the screen will be back to normal
until it decides to dim the screen again.

This is reproducible and can be repeated as many times as necessary.
