At the moment it uses just a few seconds of inactivity after that ubuntu reduces the brightness of my screen. Where do i find the option to increase this value?

This is the "Regard computer as idle after" slider on System → Preferences → Screensaver:
Or the gconf key /apps/gnome-power-manager/backlight/idle_dim_time
, which you can set thusly:
gconftool --type int --set /apps/gnome-power-manager/backlight/idle_dim_time 120
which will set the timeout to 120 seconds.

thanks, it's the gconf key. It was default set to 10 seconds. For others who are interested in this issue. You can easily check what's the value of the key via gconf-editor. press Alt + F2 and then type in gconf-editor and search for the key as Iain posted.– NESDec 13, 2010 at 16:38

the gconf key does not work anymore. how can this be done in ubuntu 11.10/gnome3 ?? Nov 18, 2011 at 20:28
You can change this setting in the menu "System / Settings / Power management". This setting can be changed if you're running on battery.
(I have the Swedish GUI so I hope I remembered the English menu names correctly! ;)
It looks like you must change the value of this key (which I made it a mandatory key, because I didnt want the users to change it.)
here's the key in gnome2 when your run the gonf-editor : /desktop/gnome/session/idle_delay
