The screen brightness controls on a Lenovo T510 do not work.  Sometimes when
adjusting the brightness up the KDE brightness OSD will display and show the
setting increasing.  But nothing displays for the brightness decreasing.  But,
no matter what, the actual screen brightness does not change.

Please let me know what additional information I can send.

Reproducible: Always

Steps to Reproduce:
Start KDE.
Login.
Adjust brightness up/down.

Actual Results:  
Nothing happens.

Expected Results:  
Brightness should change.
