@karel this evening I'm trying to find a safe way to reproduce the error, then I'll switch to GDM and see if that fix it...

I like the idea of lightdm being too fast, but I have no evidence. Since I installed the 331 nvidia driver the problem described in the first post seems to happen at random, but it seems not to present when there has been some kind of Xorg crash. In particular I've seen that using a faulty mouse (hw problem, don't know what exactly) lightdm starts every time (with a stuck pointer and an apport instance willing to report a problem with Xorg). Anyway Xorg starts sometimes even when there are no errors to report (even after shutdown instead of reboot). Next time it has issues I'll post the logs

I followed the purge/reinstall thing... The result was that unity-greeter did actually boot but with a very weird resolution (black borders, wrong proportions...) and lspci -v on the Kernel driver line said something on the lines of "can't access the device". Since the size and the proportions match those of the Plymouth boot I suspect it was using the framebuffer driver. Anyway, on a hunch I enabled the x-swat ppa and the 331 nvidia driver. After rebooting everything seemed fine, but sometimes the original black screen issue represents itself (see above).

Today I tried your suggestions, but sadly there was no change whatsoever :(

I'll try this solution too, but the issue presented itself from the beginning (fresh install) when there were no nvidia drivers installed (only nouveau)...

I'll try using GDM but the explaination doesn't sound right... If it were this kind of problem, light-dm should always be too fast, I can't find a reason why should it boot correctly only after sudoing unity-greeter, getting the error and rebooting, unless this triggers some kind of "safe mode" different from the usual Xorg safemode (the one asking you to reconfigure Xorg, go to a terminal etc...)

Already tryied that, sadly it doesn't help. Anyway never said anything about an Intel CPU, in fact it is an AMD and it doesn't have integrated graphics... thanks anyway :)
