The open source AMD drivers are not a solution; I was obliged to switch to proprietary drivers because X/lightdm kept crashing on startup leaving me only with VTs to trouble shoot. Now with the proprietary drivers I can't see the VTs.
The open source drivers every once in a while stopped loading the lightdm greeter. Reinstalling/reconfiguring lightdm and other steps didn't fix the problem. The /var/log/lightdm logs showed errors "Segmentation fault" in the x-0.log and "Process xxxx terminated with signal 6" in the lightdm.log.
