Running 12.04 server with GUI. Server had sound and mouse under 32bit version, formatted and installed 64bit version. Mouse and speakers worked fine with 32b, but speakers aren't recognized under 64b. I just brought the machine home to do some work over our 3 week holiday, and now the mouse doesn't work! (ps2). Same equipment, different place. Don't know where to start. I don't have a usb mouse to try, but the mouse was fine this morning at school.
