How to Resolve “unable to launch “X session cinnamon-session-cinnamon””

When I boot up my Linux Mint machine, I am greeted with a login screen, and when I press the enter key to complete the login process, I found a simple error message that clearly states, “Unable to launch “cinnamon-session-cinnamon” X session — “cinnamon-session-cinnamon” not found; falling back to the default session.”

This is the first time I discovered some issues with Linux Mint that were not the fault of the distros because, as I recall, I was attempting to remove some packages when I carelessly pressed the “Y” key without first checking the list of dependencies, resulting in a crash.

Although the problem was not big, I easily fixed it in a few minutes, and I’m sure you too will fix this issue in a zap. To learn how to fix this issue, be with us.

To get into TTY mode, press Ctrl+Alt+F2, which will ask you to enter your login credential. Please do so and wait for my next instructions.

Step 2: On Linux Mint, install the missing Cinnamon Desktop.

After getting logged in, you need to update the current repository and run the final command, which will install the Cinnamon Desktop window on your system.

To update the repository, you can run the below command in your terminal window.

$ sudo apt update && sudo apt upgrade 

The next command you need to fire is listed here:

$ sudo apt install cinnamon

Step 3: Reboot

Once everything has been completed, you must restart your system to view the changes. To restart the system, run the reboot command on the tty interface, and when the system is ready to accept the command, try to login, and you will find that your problem is resolved.

That’s all it takes to resolve the issue described above.
