I am very new to Gaming on Ubuntu and so I have listed the problems that I am facing with several games.

Open Arena :
Working fine

Alien Arena :
No response

Urban Terror :
Keyboard stops working, there is always a square box near the shooter's hand of about 3cm x 3cm in 800x600 resolution. Do not know how to play it in stand alone version.

Counter Strike Condition Zero :
How can we install it ?

Quake :
Missing data; see /usr/share/doc/quake/README.Debian

Quake 3 Arena :
Use game-data-packager to build and install the quake3-data package.
You will need these two files:

--------------- baseq3/pak0.pk3
