installed linux mint on my laptop. looks good. and after changed the sound driver, everything is working perfect.

the sound issue is a little bit tricky. using the default alas, the sound effect is just terrible. As a professional consultant I can't stand that.

However after changing to oss, the chrome native html5 stop working so my new extension can't pronounce word for me. need to figure out some way to solve that.
update: problem solved, installed libasound2-plugins, now the sound quality is as good as under windows
nice!

by the way, linux Mint is a nice distribution, i will recommend this. the interface is quite neat and it has those rmvb, mp3 codecs as default. which is handy.
