Alien arena 7.51 is not working at all in either Unity or GNOME Shell. I am using a Thinkpad T510 with nvidia NVS 3100 discrete graphics. When I press the icon nothing happens. Alien arena worked in Ubuntu 11.04 64 bit on the same laptop.

Hi! I would suggest you ask a new question for your second problem. For now I've edited it out. You can find the info here:, and just copy and paste it to a new question. – RolandiXor Oct 18 '11 at 10:51

Maybe you can try:

rm -v ~/.config/alien-arena
mkdir -p ~/.config/alien-arena
