I was very much disappointed when i installed Skype in Fedora, three causes which are as follows in the order. First, Skype for Linux is very old version (2.2 beta) than the Windows Skype, second, the video was too dark or black, and third cause surfaced after i installed Fedora 16 x86_64, no 64 bit binary for Fedora was available. The third one was solved as described in this post: Running Skype for Fedora x86 in Fedora x86_64. For the first one i can’t do anything, but there should be some solution for the second problem: dark video. Cheese (a video capture application) works fine and video is good. Searching in the skype forums got a lot of mumbo jumbo solutions of which none worked. After a lot of search i got a very simple solution.
Edit (16.06.2012): The first problem seems to solve atleast upto some extent as Skype 4.0 is now out and can be downloaded here.
