Ubuntu 10.04 Cant Adjust brightness on my lenovo Thinkpad?

rated 0 times [ 6] [ 0] / answers: 1 / hits: 6682 / 2 Years ago, fri, january 7, 2022, 2:57:25

I cant seem to be able to adjust the brightness on my think-pad laptop running Ubuntu 10.04. In the power management applet it shows that the power is set to 100%, but even if i try to lower it the actual screen brightness dosent change.

Any ideas of how I can get around this?

I tried changing the brightness from the terminal but its already set to Max brightness (however the actual screen brightness is no that bright at all).

Thanks

oh，I've met this problem before.All you need to do is:

sudo gedit /etc/X11/xorg.conf

find segment like this:

Section "Device"

Identifier    "Default Device"

Driver    "nvidia"

Option    "NoLogo"    "True"

EndSection

change it like this

Section "Device"

Identifier    "Default Device"

Driver    "nvidia"

Option    "NoLogo"    "True"

Option "RegistryDwords" "EnableBrightnessControl=1"

EndSection

JUST ADD THIS LINE: Option "RegistryDwords" "EnableBrightnessControl=1" !

Then restart,It will work.
