Unable to log in to Ubuntu because of ‘failed to start session’ error? Here’s what you could try.<\/p>\n\n\n\n

I was trying to log in to Ubuntu as usual. I entered my password and it did not log me in even with the correct password. Instead, it showed me failed to start session<\/strong> in red colors. I could not even log in to the guest session.<\/p>\n\n\n\n

In this quick post, we shall see how to fix failed to start session issue in Ubuntu 16.04-20.04 and earlier versions.<\/p>\n\n\n\n

Fix failed to start session in Ubuntu<\/strong><\/h3>\n\n\n\n

The reason here is that somehow your Unity desktop has been messed up. You can try several way to recover it. Let\u2019s see how to do it.<\/p>\n\n\n\n

When you are at login, press Ctrl+Alt+F1<\/strong>. It will take you to command line interface from the GUI. In here, type your username and password. Now, you can try the following command to install Unity Desktop:<\/p>\n\n\n\n

sudo apt-get install ubuntu-desktop<\/code><\/pre>\n\n\n\n
If it is already installed, try reinstalling:<\/p>\n\n\n\n
sudo apt-get install --reinstall ubuntu-desktop<\/code><\/pre>\n\n\n\n
Once it is installed or reinstalled. Use the following command to reboot the system:<\/p>\n\n\n\n
sudo reboot<\/code><\/pre>\n\n\n\n
It will reboot and bring you back to login screen. Try login now. You should be able to log in. If you are still unlucky, try to use the alternative below:<\/p>\n\n\n\n
Alternative method:<\/strong><\/h3>\n\n\n\n
As an alternative you can use the command below to reconfigure the packaging:<\/p>\n\n\n\n
sudo dpkg-reconfigure -a<\/code><\/pre>\n\n\n\n
At times, this should fix the failed to start session issue in Ubuntu. But it was not that easy for me. I used another approach which is slightly dirty. When I noticed that reinstalling Unity and reconfiguring the packages did not make any difference, I installed GNOME instead using a command like this:<\/p>\n\n\n\n
sudo apt-get install gnome-shell ubuntu-gnome-desktop<\/code><\/pre>\n\n\n\n
This time at reboot, I was able to boot in to GNOME desktop or even choose to boot in to Ubuntu default, i.e. Unity. A word of warning, Unity may seem broken after installing Gnome. Change the theme and icons to that of Ambiance, instead of the default (Adawita).<\/p>\n\n\n\n
That helped me fix \u201cfailed to load session\u201d error in Ubuntu<\/strong>. Did it work for you? Do let me know if you have questions or suggestions.<\/p>\n\n\n\n
