How to solve “failed to load session “Ubuntu””

Disclaimer: This post is not originated by me. I post it here just for reason of backup.

> it’s “failed to load session”

Repair attempt.
Please open tty (virtual console, text mode only): ctrl+alt+f1
sudo apt-get update
sudo apt-get install ubuntu-desktop
sudo apt-get -f install
sudo dpkg-reconfigure ubuntu-desktop
sudo reboot

If above wasn’t sufficient try:
sudo apt-get install gnome-session
sudo apt-get install lightdm
sudo apt-get install unity-greeter
sudo dpkg-reconfigure lightdm

## The install commands will tell self-explanatory if it’s already installed or not.

Just in case, the same can be done via recovery mode.
Press [Shift]-key right after boot to view boot menu, select recovery mode and select root shell (no need for ‘sudo’ there).

You could also view log file in either one of them in order to verify if essentials have been removed and install it again.
sudo nano /var/log/apt/history.log

    Thank you for the post. Reinstallation of the Linux kernel led to problems when an unexpected power failure occurred. Ubuntu desktop refused to load. This script worked perfectly. Thank you again!

    generally, I don’t find fix-it posts to usually work for me, but this was spot on! Thank you very much. I had tried many other options, but this was the fix.

    Unfortunately this did not work after I uninstalled Unity 2-D in 12.04. Got a load of error messages in Recovery Mode after “apt-get update” seeming to do with inability to resolve and/or unable to parse. None of the commands worked. Sigh…… I’ll keep looking. Finding Linux solutions can be like looking for a needle in a haystack.
