[mja123]

hi i just switched from xp to Ubuntu and i installed steam and half life and guild wars and i cant seem to get it to work right. Every time i try to run them they begin to load up then when they are about to start the screen goes blank for a second and then im back at the desktop and the computer is acting almost as if the program is running but its not and the resolution is the games plz help. 


PS - i  don't really know computer language that much and i don't know how to use the registry.

                                                                                            thanks for your help!!! :)
