The ACER Aspire 3680 is great for Linux all except for the Sound Card and WiFi. This can be easily fixed.
Open your Konsole and type alsaconf
Agree and continue. Hit YES.
Now type Kmix
Unmute the sound.
Thats it. adjust your volume.
As for the WiFi just take off the bottom middle panle and unhook the internal WiFi card and wrap the antenna hookups in electrical tape. Put your own WiFi card in.
Also if you want to run Linux take that laptop back to the sore (Wall mart) and tell them you don't agree with the Microsoft End User License Agreement and show them where it says you will get a refund.
