Thanks Foxhound for your tutorial how to run Arma2 on Ubuntu.
I followed it and come even to main menu in Arma game, but further I can't go. I'm not able do press any button on main screen where I could make graphic options lower, or even exit the game.
I'm beginner in Linux, and Arma worked fine on Windows7, so hardware requirements are fulfilled.
Any suggestions how to get it to work, as I'm not getting back on Windows for now.
Thanks in advance.
