Hi, I recently installed Loki on a Thinkpad x220. Everything works well, but when I tried to add another user account and restarted, although there was an icon for another user, I couldn't select it to Login. The Login screen previously worked in Freya with alternative users. I have tried installing with a hard drive an SSD using an older download and a fresh download, but the problem persists. I have tried to find other examples of this problem on the StackExchange site and on Ubuntu forums, but haven't seen anything similar. I would be grateful for any pointers to troubleshoot this issue, or even if other users have encountered it.
