You can change the time of inactivity after which to turn the screen off from terminal using next commands:

gsettings set org.gnome.settings-daemon.plugins.power sleep-display-ac <nr_of_sec>

gsettings set org.gnome.settings-daemon.plugins.power sleep-display-battery <nr_of_sec>

gsettings set org.gnome.desktop.session idle-delay <nr_of_sec>

Change <nr_of_sec> as you wish. For example, for 3 minutes, use 3x60=180:

gsettings set org.gnome.settings-daemon.plugins.power sleep-display-ac 180

gsettings set org.gnome.settings-daemon.plugins.power sleep-display-battery 180

gsettings set org.gnome.desktop.session idle-delay 180

If you will use 0, the screen will never turn off.

To change the brightness through terminal, use this answer: https://askubuntu.com/a/56171/147044. I tested this method on 13.04 and is working.
