I just had a problem with my skype that I couldn’t login due to previous instances having been closed but for a mysterious reason the process was still hanging over there. So, in short I couldn’t log into my Skype. So here is what I did to kill those processes you see below:
root@support-desktop:/home/support# ps ax | grep skype
2828 ? Sl 16:33 skype
21721 ? Sl 0:04 skype
