After I installed Skype on Ubuntu, it automatically starts whenever I log in. I hate softwares that automatically start upon log in. To top, there is no option to disable the automatic start unless you log in into skype. I didn't find any option to disable skype upon startup ... Grrrrrrr ... although I found a way to start it minimized (Log in into skype > Options > Advanced > Start minimized). Sad, they would make softwares like this.
