    Thanks a lot. This completely ruined my system. The system now starts without X, and there’s no x server or windows manager installed anymore, and no network. How incompetent is it possible to be? You post this to unknowing non-techies? You, sir, are a f…ing idiot and should be banned from posting or writing here.

    The part that ruins your systems is the “sudo apt-get –purge remove … … ….” section, if you are happy to leave redundant binaries / config files on your system you can safely ignore that commands. The other steps he mentions are perfectly safe and do the job.
