Whoop whoop~ Good on you. Ubuntu will start to wear on you after a while. That or it will break. >>; That's pretty much been my experience with it. As for games, if you have a dedicated graphics card you should probably look into the good drivers for it, that's all I can think of. That being said, happy birthday!
Lucky you. I still have my old Win7 Laptop, and already it's been giving me trouble. I switched the OS over to Ubunutu to give linux a shot. It's not bad, and I can run SOME of my old windows programs on it all except for my PC games. I mean, I can play them, but they lag hard under Linux; until then, I'm emulating some old SNES and Gameboy Games.
Hope the bug dies before it gets worse!
Also, by the time you get this msg, Happy B-day to me. XD
