I've hit another annoying problem. I cannot change brightness
level.
The
Fn keys don't work at all, when changing it in the user menu or power
management settings it changes the backlight randomly in one of ten
attempts. Moreover indicator in the user menu always shows zero level
of
backlight.
I always blamed drivers or something lower in the graphics stack for
this. But it works perfectly in KDE and I can also change backlight
with
xbacklight or xrandr.
I'm using up-to-date Fedora 20+GNOME 3.12 Copr on Lenovo X240.
Anyone has hit the same problem?
BTW the more I'm using GNOME 3.12 the more I think it's not ready for
the prime time. I'd rather wait for fixing releases.

I fixed this on mij Lenovo bij adding << Option "RegistryDwords"
"EnableBrightnessControl=1" >> to /etc/X11/xorg.conf in the
"Device"
section:
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
