I am VERY newbie with the Ubuntu system, let say that in the first place. Ok, the install was very easy and intuitive. From the software center i got Wine and install it too. Then i get the latest 3d drivers for my graphic card and finally install the Steam without problems. Download Counter Source really fast and ....when i try to execute it, does nothing. No errors, just the clock thinking a few seconds and then nothing. Please, ask me everything you need in order to help me. Thanks a lot and sorry about my poor english.
