Not a lot, nice xubuntu splash screen and then it gets to where it would start the display manager and that's it, black screen, nothing responds, can't switch to another VT, system doesn't even respond to soft power off.
It's fairly a fairly unhelpful thing to debug, I should start the system without X and see what happens etc..
Instead I think debugging time can be spent making tofu wraps with a load of sriracha sauc
I've developed an unhealthy addiction to sriracha in the last year.
Sorry I appear to have been called with -vvv this evening.
