Adjusting Brightness issues

[Guest]

I just recently installed kubuntu on my machine, a gateway M series, and i am having issues with adjusting the brightness of my screen. When I attempt to adjust the screens brightness via the battery icon, it has no effect not matter where I move the bar. I have an nvidia chipset. Thats about all I know at the moment. any guidence would be greatly appriciated

Welcome to linux and to KFN. Nice to see new members.

Do you know what nVidia graphics chip set you have? There are members here who use nVidia graphics cards/chips, so watch for one of them to chime in with suggestions. I'm pretty sure that it will involve installation of the appropriate 'driver' so that you have the nVidia Control Panel (or what ever it is called) to make changes with.

Re: Adjusting Brightness issues

it appears that I was mistaken, I have a intel chipset,

Chip Type: Mobile Intel(R)4 series Express Chipset Family
DAC Type: Internal
Adapter String: Mobile Intel(R) GMA 4500M
Bios information: Intel Video Bios

I dont really know graphics stuff so I just listed as much as possible

Re: Adjusting Brightness issues

Check to see if you have the following packages installed. Open a console and type:

sudo apt-get install --simulate acpi-support hotkey-setup

If they are already installed, you'll get:

Reading package lists... Done
Building dependency tree
Reading state information... Done
acpi-support is already the newest version.
hotkey-setup is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

If neither is reported as installed, then type:

sudo apt-get install acpi-support hotkey-setup

Afterwards, see if you keyboard brightness controls work. On my Toshiba Satellite, it's the Fn+F6 (lighten) and Fn+F7 (brighen).
