What commands did you run to back up and restore the system?
Is '/tmp' a tmpfs filesystem? If not, did you back up and restore it?
Did you exclude '/run'? If not, did you restore it?
Did you create '/proc' and '/sys' with the right ownership and mode?
If this is a Debian system, is it a non-standard install that doesn't
use udev (AFAIK this is still possible)? If not, there's no point in
backing up and restoring '/dev'.
If this is an Ubuntu system, the default '(recovery)' grub entry will
have 'nomodeset' appended. Try that when you add 'single'.
Are you using a DM?
Are you using a WM or a DE?
Have you looked at the logs? Especially Xorg.0.log and xsessions-errors.
Can you launch X after logging in to the console?
