Failed to load session "ubuntu"

Question

I installed CCSM to enable window previews in Unity. But when I went into extras, there was no 'window preview' option.

So I tried experimenting with other options in Compiz and now there are no borders in the dialogue boxes (close, minimize, restore buttons are not there, I had enabled some 'flat....' option in Compiz.

Later, I uninstalled Compiz and then reinstalled it. Now it says

"Failed to load session Ubuntu"

I can't even access through the guest account, I am new to Ubuntu.(please explain in detail).

All I have access to is the login screen (it still shows my custom wallpaper). Please help, I don't want to lose my stuff.

I got the same problem ""Failed to load session Ubuntu"" when I was trying to login afer uninstall Compiz.

I tried to boot from USB with Live Ubuntu inside and others ways but it doensnt work.

At the end, it comes up with a simple solution.

Boot your Ubuntu as normal
When you see the log-in screen, try to Ctrl - Alt - F1
In my case (ubuntu 12.10), a blank screen appears. dont be panic, try Ctrl - Alt - F2
A login console shows up and ask you to login using your id and password.
After login. Run these commands. (tested)

sudo apt-get update sudo apt-get install unity-2d sudo apt-get install ubuntu-desktop sudo apt-get install compizconfig-settings-manager sudo apt-get install compiz-plugins-extra sudo apt-get update

I got this above list of commands from How can I remove and re-install Unity? but some doesnt work so I mentioned only good-running command in my case. I highly recommend to restart your system before try to login again.

sudo shutdown -r now

Hope it helps you to solve your problem.

sudo dpkg-reconfigure ubuntu-desktop did the trick for me, thanks! – legends2k Jul 30 '13 at 21:34
Very good. sudo apt-get install ubuntu-desktop did the job for me because I updated ubuntu OS – Onimusha Dec 17 '13 at 15:15
This had no effect for me. – Cerin Oct 01 '14 at 05:59

For me it seems to have been related to having a Cinnamon desktop installed that I was playing around with. Once I removed it using Failed to load session "ubuntu" - Ubuntu 13.10 on MacBook Pro everything was fine. ( I don't have a macbook pro, it was the same on my Dell desktop).

Same here. I removed cinammon as package, but a bunch of dependencies were still there. So I started removing cinammon-session, cinammon-desktop-data, etc. – grosshat Apr 23 '14 at 12:19

Try booting into the LiveDVD and install Compiz. It's possible that you disable Unity. Update Unity.

Add the following PPA to your Software Sources per these instructions: ppa:unity-team/staging sudo add-apt-repository ppa:unity-team/staging

After adding, open the 'Software Updater', click ‘Check for Updates’, and proceed to install those you’re prompted to do.

This can also be achieved via the Terminal by running:

sudo apt-get update && sudo apt-get dist-upgrade

Restart your computer.

You'll see a n/w sign between chat (letter-like logo) and volume/audio on top-right corner. Make sure n/w is enabled. – TomKat Oct 24 '12 at 18:43

Bhai, thodi der ke liye taar (ethernet) ghused le na. Plus, wired n/w are generally faster than WiFi. Don't kill me if you're using an engg college WiFi. – TomKat Oct 24 '12 at 18:49
