Unable to launch "cinnamon-session-cinnamon"

Question

I just tried to boot Linux (I am using Mint), I got the following error:

: unable to launch "cinnamon-session-cinnamon" X session ---
"cinnamon-session-cinnamon" not found; falling back to default session.

Normally when I would login in, there would be a little mountain logo thing in the top right corner of the little login box, as seen in this picture: But now when it is giving me that error, when I login, there is no logo in the corner... which is a little odd.

---

When I started composing this question, it suggested this question

The only problem with that question/answer is that when I click "okay" it doesn't load anything (or at least that what it looks like). I can press ctrl+alt+leftArrow or ctrl+alt+rightArrow and I see the little window to switch workspaces, but that is about it... I can't tell if the terminal opens up when I press ctrl+alt+T. I tried doing the shutdown command to see if the terminal was open and I could give commands, but it doesn't seem to work.

How can I fix this?

Solution

From your description I think cinnamon package is not installed or cinnamon-session-cinnamon command deleted/removed.

Try this steps:

• Press CTRL-ALT-F1 to change to text mode and login with your user.
• Change user to root with su or sudo command.
• Check package and program:
  • Query Cinnamon packge is installed or not: dpkg -l cinnamon
    • If there is no reuslt, the package is not installed or deleted/removed, install package: apt install cinnamon
  • If package installed (there is result dpkg command), list command: ls -l /usr/bin/cinnamon-session-cinnamon
    • If there is no reuslt, the package is deleted/removed, reinstall it: apt reinstall cinnamon
• If there are results both of them commands check ls output again, you should see permissions like this: -rwxr-xr-x
  • If your permission is different, set it: chmod 755 /usr/bin/cinnamon-session-cinnamon
• Reboot your computer.

I hope it will help you.

Thank you so much! This did help me a lot... though there is one thing that you should add/change. When I did the apt reinstall cinnamon command it said that cinnamon would not reinstall because it wasn't currently installed.So I just did apt install cinnamon and it worked. So you should say something like "If it tells you that cinnamon isn't installed so it won't reinstall, do this command: apt install cinnamon.
