Possible to change screen brightness with C?

Question

Using C in Linux, would it be possible to change the brightness of the viewing screen? This isn\'t expected to be portable other than running on my installs of Ubuntu and Fe

Answer 1

I'd start with selecting from the following list of ubuntu pacakges, the tool that allows you to manage your screen's brightness (hint: it depends on the brand)

nvidia-settings - Tool of configuring the NVIDIA graphics driver
smartdimmer - Change LCD brightness on Geforce cards
armada-backlight - adjust backlight of Compaq Armada laptops (E300, M500, M700)
ddccontrol - a program to control monitor parameters
eeepc-acpi-scripts - Scripts to support suspend and hotkeys on the Asus Eee PC laptop
fnfxd - ACPI and hotkey daemon for Toshiba laptops
gddccontrol - a program to control monitor parameters
spicctrl - Sony Vaio controller program to set LCD backlight brightness
tpb - program to use the IBM ThinkPad(tm) special keys
xfce4-power-manager - power manager for Xfce desktop
xfce4-power-manager-plugins - power manager plugins for Xfce panel
xvattr - Utility to change Xv attributes

Once you have selected it,

sudo apt-get build-dep 
apt-get source --compile  

should get you on the right track
