[Bug 835971] [NEW] screen brightens when idle, rather than dimming

 

Public bug reported:

This may be related to the bug #498974
(https://bugs.launchpad.net/ubuntu/+source/gnome-power-
manager/+bug/498974)

When the screen is turned to a high brightness, if I haven't touched the
keyboard or mouse for a while the display will dim a bit. This is
normal.

However, when the screen is at a low brightness, at idle the screen will
actually brighten instead of dim!

It seems like the "brightness to dim to" is a hardcoded value, rather
than relative to the current brightness. Hence, the hardcoded
"brightness to dim to" is actually brighter than what I have my screen
set to.

It seems related to that other bug, but the symptoms they report are a
little different. Mine just gets a bit brighter. The other bug report
describes the screen getting to full brightness before dimming somewhat
again, ending off with a higher brightness than when the keyboard and
mouse are not idle.
