I'm running 12.04 and I've installed skype via the software centre.
As with 11.10 everything works fine with 12.04 as well.
There is only one thing that does not work. I can't see myself in Skype video calls. The video call works fine, I can see the other side the other side can see me. Buid in microphone works.
If I click on 'show myself' during the video call nothing happens. I know that it works on Ubuntu in general as I had it working a while back on a different machine (Xubuntu 11.04). Could that be related to the GPU? I'm now on a intel/nvidia one.
Any Ideas where I can hunt for some options or tweaking?
I'm running on a nVidia card as well and it works for me.
Try reinstalling Skype and updating the nVidia drivers. Then when in a Skype call, click the blue video icon and then click "Start my Video".
