Hi I was looking around the net for a really good linux distro to replace windows on my desktop i found linux mint 11 , it was very fast, got to work all of my hardware but i can't install xbmc on it i can't configure my xonar dx. It's frsutrating cause i only wan't to watch my movies from my bed with my remote kayboard in my hand

i love xbmc i had it on windows but i hate the bluescreens and the viruses etc... can anyone give me a hint what for an os i should use with xbmc on it? ps. I have a tv as my second screen where i usually run xbmc but i also use my monitor for doing the pc stuff
intel core duo e5200 , 4G ddr2 ram, nvidia 9800gt, asus xonar dx with optical cable to my yamaha home theater amplifier 5.1 system and LG 22" monitor and LG 42" LCD tv on hdmi cable attached...
