Unable to launch cinnamon-session-cinnamon error

Post by Lilmothiit »

When I booted up my linux machine this morning, I got the following message:

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

I was then taken to a black page with nothing but an arrow cursor and the ability to launch the command line via Ctrl + Alt + F2

I assumed I had just borked my computer playing around with some new programs (virtualbox) so I did a fresh install. Got it working how I wanted, installed the updates (default update settings), shut it down to make sure it was working... and got the same error message on start up.

I did update cinnamon, and install cinnamon nemo from the update options. And I also uninstalled pulseaudio, but I did that a few days ago originally and this didn't happen any other time I booted up my laptop.

I am currently running linux off of installation disk. I don't know if this will affect the inxi -Fxz command or not, but here is my system data (less than two hours) after a fresh install.

I had all my data backed up, but this is extremely annoying!

There's aparently an issue with Virtualbox guest additions:



Code: Select all

apt remove virtualbox-guest*
and if that doesn't resolve it, then:

Code: Select all

apt install --reinstall cinnamon
sudo systemctl restart mdm

I know this is an old post, but had this happen just now - reinstalling cinnamon seemed to fix it. Thanks!

I have a similar problem.
My system was busy with an update and asked me to restart, when I did - it broke!
Unable to launch "cinnamon-session-cinnamon" x-session --- ""cinnamon-session-cinnamon" not found; falling back to default session

I have Linux Mint 19 Cinnamon
I know basically nothing about Linux.
When I go Control Alt & F2, I can see all my data.
Unfortunately I can't see any disks I connect to make a backup (I also don't know how to do it :cry: )
I created a boot disk which seems to work, but then I don't see any of my data. I have an option to reinstall Linux Mint, but it tells me I will loose my data.
How do I fix this problem without loosing my data?
