Hi
The brightness button are working properly in Windows 7.
The problem arises while using under FC14. Indeed it appears that the brightness
buttons are not scaled correctly. I tried to set the power management so that there won't
be lower brightness when working on battery but it had no effect.
Following this a message I received a suggestion from Vinzenz Vietzke to add
a line
Option "RegistryDwords" "EnableBrightnessControl=1"
Option "RegistryDwords" "EnableBrightnessControl=1"
to file /etc/X11/xorg.conf.
However, while there is such a file in RedHat Enterprise distribution,
the FC distribution does not have such a file. None in FC12
in FC14 there is a /etc/X11/xorg.conf.d directory where the keybord conf file
resides.
So, the problem still exists
Thanks for your support,
Eran

Hello
I wonder if someone encountered this problem:
I have just received a brand new Lenovo T510 Laptop. I have installed,
successfully, a Fedora 14 system. This is a dual-system machine, with Window
7 Professional also installed.
The problem: Staring the machine in Fedora, unplugged to electricity, the
screens dims down to hardly readable level. Trying to increase brightness,
using the function+brightness button has no effect. Plugging to electricity
restores proper brightness.
Another show up of the same problem: started plugged in with proper
brightness, than any touch of function+brightness key brings the screen to
unreadable, and unchangeable brightness. Seem to me that the eFedora 14
scales the potentiometer of screen luminosity incorrectly.
Some information: Working in Windows 7, on the same machine: this does not
happen
On previous Lenovo, T60p, with Fedora 12, this
did not happen either.
Has anybody encountered this problem ? any clue how to resolve,
Thanks,
Eran

It seemd hat your brightness buttons are not working. Could you please try to change brightness via the power manager. And which de are you using?
