Won't boot into desktop after idiot (me) changed something

[MS]

Glad you did not have to reinstall the system, it is always annoying and apart from that, I have had no idea how to help you out accessing bash in the case given - maybe others here around would - so yeah, I am a noob as well, do not feel ashamed to ask qustions, maybe one blind trying to help the other will not lead to falling into a massive black hole.
