I recently installed Ubuntu 13.04 on my Lenove IdeaPad Y580 and Google Talk to make a video call only to find out that the camera is not working. This problem did not occur when running Ubuntu 12.04 and 12.10.

What I did was ran: gstreamer-properties and this is what I got:

(gstreamer-properties:6510): Gtk-WARNING *: Unknown property: GtkDialog.has-separator

According to Lenovo Support (http://support.lenovo.com/en_CA/research/hints-or-tips/detail.page?&DocID=HT073649) this computer uses an AzureWave webcam.

I was wondering whether you compiled the alx module yourself and installed it before the webcam issue began, because that's what's going on on my end. The default alx module in 13.04 for the AR8161 Ethernet card doesn't work for my Y580 and when I make my own from compat-drivers and install it, the webcam stops working. alx somehow screws with another module, uvcvideo, which is needed in order to access the camera feed. After I install alx myself, uvcvideo is no longer loaded at startup and I can't load it manually, if I try "sudo modprobe uvcvideo" I get something along the lines of 'uvcvideo' Invalid argument

It turns out that the makefile that was in the tar.gz I downloaded from a link included some other modules in the make sequence (videodev and something other from v4l2...) So, I didn't install just alx, I actually overwrote some other modules which were working just fine and in the end, it was the unintentionally built videodev that conflicted with uvcvideo, so I solved the problem by installing the 3.9 kernel and modifying the makefile so it would build only the alx module and everything went great :) Now I've got both a working Ethernet card and a working webcam.
