I've got a "light desktop manager" entry in Ubuntu greeter for some strange reason, and I can't get rid of it. As the current OS is Ubuntu 13.10 the way to configure the lightdm greeter is rather strange, and I can't find any solution in greeter configs.
A more annoying thing is that LDM seems to have password very hard to guess so I can't login to this "account".
Can you help me to find what is causing this problem and find the solution?
