Comment 247 for bug 1493888

Thanks Philip. The link to Ubuntu 15.10 boot hangs when starting lightdm helped me too. I had my system set to auto login to my user account but I could not log out or disable the auto login without having lightdm hang on startup. Now I can logout again!

According to that link, in the Ubuntu 15.10 release notes, they said to uninstall fglrx before upgrading to 15.10. That would have avoided the problem lightdm hanging.

I still have an issue where Ctrl-Alt-F1 to F6 do not work for me when fglrx is installed but that is probably a separate issue.
