Gaming: Increasing the Brightness for Urban Terror in Ubuntu 12.04

The only game I ever play is Urban Terror, but since Ubuntu 11.04, 11.10 and now 12.04 LTS, even the maximum brightness setting in UT is still very dim on my laptop. So I ended up using a script to start the program with the following settings to increase the brightness.

In the assumption you have installed UT in the ~/Games/UrbanTerror folder, type at the command prompt: (substitute the correct folder if yours is different)
 

gedit ~/Games/UrbanTerror/utstart

copy and paste the following code and save/exit.

#!/bin/bash

xgamma -gamma 2.2

~/Games/UrbanTerror/./ioq3-urt

xgamma -gamma 1

If "-gamma 2.2" is not bright enough for you, you can increase this value.

Adding this script-file to the Menu so you can fire it up from the dashboard:
open main menu editor and add and item in the games section:

In our case the command is: ~/Games/UrbanTerror/./utstart

enjoy the game.
