I recently installed Linux Mint Debian edition on my Lenovo x120e. Everything is working pretty well.
I got the sound working by following the instructions here: http://www.dei.unipd.it/~pettarin/debia ... x120e.html
However, the volume buttons (i.e. Fn - Esc, F1, F2) don't actually change the volume. When I push them, the OSD shows up but the 'progress bar' thing is completely empty and nothing changes.
When I used the Live CD the volume buttons did work. The 'volume control' also looks different to the one that was on the liveCD version.
I've been lurking on the forum for a little while -- thanks for all the help already!
