So I have absolutely never used Ubuntu before. Shortly before Windows 8 release Valve started investing in making Steam for Linux and peaked my interest in giving a Linux OS a shot. I've installed 12.10 onto my boot SSD using the Windows Installer, but whenever I reboot and choose Ubuntu I get a purple screen some flickering, then it just freezes there. I assume I need to adjust something with my graphics drivers (GTX 680) to get into Ubuntu and install updates. I've tried to piece together the idea across a couple different places and understand I need to edit the boot string from quiet to noquiet, splash to nosplash, and add nomodeset to possibly get this to work. Things is I have no clue where to get there. Was hoping someone can hold my hand through this for a complete Ubuntu noob at the moment. Thanks for any help!
