The rsync overwrote your new working desktop config with the old broken desktop config. > Not wishing to create tom3 I tried installing xdm.

Since the problem was in the files in your $HOME changing stuff in the system is just going to confound the issue with additional noise. Very likely your system is fine. If you were to create a pristine user again I expect you would be able to start a full desktop again. > Reinstall would certainly cure all my mistakes.
