I'm running Slackware Linux on a Samsung NC 110 netbook.

None of the Fn keys work exept for the audio volume level keys.

Currently I can control the brightness of the display with this command:

echo -n 6 > /sys/class/backlight/samsung/brightness

I would like to use this netbook with a projector but I can't switch the display without the use of the Fn keys. Is there an alternate way to send the display to a projector without using the Fn keys?

How much do the keys not-work? If you run xev | grep -i key and press your Fn-SwitchDisplay combination, do you get any output? – Ulrich Schwarz May 4 '12 at 6:33
No, it gives an output only with F11, F12, Pause and volume controls. – xonya May 5 '12 at 17:29

It is possible with xrandr to enable another display output.

If you're using a desktop environment (KDE, GNOME, XFCE), most likely it has a configuration tool to enable the video output and configure the resolution.
