nc10 brightness issues on xubuntu

[johns-andy]

Using samsung nc10
xubuntu - xfce 4

Only really been using linux for the last few weeks on my netbook so not really sure on what i'm doing as of yet. been reading up forums trying to work this out but unable to find anything so hoping someone can give me a step to step guide if pos.

Finding everything installed all okay on the nc10 apart from the brightness of the screen is very dim and unable to find how to change this.

i have tried looking at various patches but these confuse me and not sure how i would apply them... i have installed xbacklight but when i run the program it advises

andrew@netbook:~$ xbacklight
No outputs have backlight property

Cheers
Johns

You should be able to set the brightness like this:

echo -n 100 > /proc/acpi/video/VGA/LCD/brightness

Although the path to brightness will probably be different from you, for example my laptop is: /proc/acpi/video/IGFX/LCD/brightness so navigate around /proc/acpi/video till you find it, then cat brightness and it will tell you the valid levels you can echo to it:

[root@tmob LCD]# cat brightness 
levels:  30 37 44 51 58 65 72 79 86 93 100
current: 100

So you could for example echo -n 44 > brightness.

Hope that helps.

If above didn't help there's an options in the display/power settings for 'dim when not on AC'

I remember having the same problem
