Skype not launching

view story

http://chakra-project.org – I set up Skype-no-pulse, tested it (without making a call) and everything seemed to work. That was about a month ago. About a week ago I wanted to use it, but it wouldn't launch. I also tried the Skype-pulse version, but that did the same. It would attempt to launch then fail. I was waiting for the systemd update, thinking maybe that would help. But I still have the same problem. I have Skype-pulse version and removed the no-pulse version, but still the same.First question: where do I find the info / logs that will help to diagnose this problem? (HowTos)
