Ubuntu installation X200 sound card driver today to buy a new small black X200, installed ubuntu-8.10 desktop, after the installation of Bluetooth, sound card, wireless, Nic, drivers are on, and then install 3D plug-in, the effect was good, but I found that the sound of playing the music was sanded, dizzy, and the sound card driver was damaged.
