I saved my home folder when I moved from 32bit Mint to 64bit Mint. Next, I installed Mint 18 from scratch, and copied home folder from backup as root user.

Now I can't get home to startup as it needs to be exclusive to user. Message is DMRC error. What should I do now?

You should be able to login as root from a tty. Most distros will not allow root to boot an X session by himself therefore you cannot do it from the GUI.

If I am not mistaken Mint uses tty 7 for the graphical display, therefore we will use tty 3. Do the following.

  • Press Ctrl+Alt+F3 to enter the 3rd tty (if that do not leave the graphical display try Ctrl+Alt+F4 for the 4th tty)

  • A login form will appear, login as root

  • Perform chown for the correct user:

    chown -R <user>:<group> /home/<user>

After that you should be able to login normally through the graphical display. Press Alt+F1, Alt+F2, and so on until you reach the graphical display.
