don't know whether its the same on ubuntu - but on the version of linux i use pressing Ctrl, Alt and Backspace brings me to the login screen where i can login as root,
if you can't login as root either then i can offer no more help
Due to the nature of online help we are not able to verify ownership, and will not be able to help bypass or recover any Windows user passwords, cd keys, license codes, serial numbers, etc.
this also applies to linux, mac, etc
I would find this different with Ubuntu as it provides a boot option that allows you to log in as root. Ubuntu uses a unique security method where they sudo only keeping the root account locked. The only way to get a root shell in Ubuntu (without unlocking root which is "unsupported") is the recovery mode boot option from GRUB or sudo -i. There is not a root password in Ubuntu.

If you can not log in to do chamber's commands, do it from the recovery mode. When prompted, select to drop a root shell. Then you can proceed with the commands but you will need to give the full path to your home directory like this:
chown -R username:username /home/username/
chmod 664 /home/username/dmrc
