Note that failure to start X isn't the only reason that lightdm might fail to start; one case I had was where the configured greeter wasn't installed and thus lightdm shut down X itself rather than X taking lightdm down.

It also doesn't provide any diagnostics on that console for anyone remotely trying to help them. Ideally it should on failure: 1) Switch to vt with a login prompt 2) Output a line or two saying that it knows lightdm failed - preferably pointing them at the log file. 3) If it can have a pattern to check for the X server itself having failed and being the reason lightdm failed then it would be useful to display it.
