[Bug 527218] [NEW] Brightness setting fluctuates fast on MSI U100

[TheKey84]

Public bug reported:

When I do one of the following actions, the brightness of the screen fluctuates very fast:
- Trying to change the brightness of the screen via hotkey or GUI.
- Change to a terminal and back to the KDE-Session.
- Attach or detach the power plug.
- Do some changes to the powermanagement settings in KDE.

It looks like one software tryes to increase the brightness and fights
against another wich tryes to decrease it at the same time. You can't
work that way. Also the brightness indicator stays open all the time
(going crazy).

When killing any process (Ctrl+C on commandline or Ctrl+Alt+Esc on GUI)
this behavior stops immediately, but only if I didn't try to control the
brightness while this was happening.

This does not happen while the login screen is shown or in text mode.
Here it is possible to control the brightness normally via hotkeys.
