Description Karel Volný 2010-12-14 09:54:35 EST
Description of problem:
When the system is waiting for user login, I cannot use the function keys to change the brightness of my laptop screen, the brightness stays on max.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. let Fedora boot to kdm login screen
2. hit the function key to decrease brightness
Actual results:
nothing happens

Expected results:
the display dims

Additional info:
hardware: Lenovo T510 - Core i7 M620 integrated graphics

changing brightness works without any problem after I log into KDE (in fact, when on batteries, the screen dims itself in the middle of KDE startup process)
Comment 1 Rex Dieter 2010-12-14 10:12:26 EST
true,  kdm doesn't support that (yet), as it currently only works from within a full kde session.
Comment 2 Lukáš Tinkl 2012-07-11 13:04:26 EDT
kdm doesn't support this, only PowerDevil does with the running KDE session. I suggest filing a wishlist item upstream
