I installed Raring last night and everything was going fine until I went to get AWM up and running.
Originally I planned to use the version from the official repos ignoring how outdated it was, but the log-in screen would not allow me to switch DE's.
So I tried using Klaus Vormweg's updated unofficial PPA and the exact same issue happened.
No matter what I do, the Ubuntu log-in will not display Awesome in the list of available DE's. At first I thought it might be the same for every environment, but I was able to install and switch to a Gnome Fallback proving that theory wrong...
Is this an issue with Raring, or PEBKaC?
P.S. I realize this question doesn't have much in-depth information behind it as I'm at my work PC now, but any terminal output you all require I'd be glad to provide once I get home.
