I have very important data on my pc

Important data means you have a backup. So you could restore that. That way all you need to worry about is getting a user you can log into. See below.

mv /home/mary /home/alex

Why did you think that was a good idea?

Files like /etc/passwd and /etc/shadow as an example do not get updated when you move a user.

The way to do this: create a 2nd user called alex from the "users" option in settings, make it an admin. Then log into alex, confirm it works. Then copy all personal files over to /home/alex and do a chown -R $USER:$USER /home/alex while logged in as alex. Do not copy over hidden files. Confirm it works and only then you remove user mary using the deluser command. Not by removing /home/mary

To fix the current problem:

• Use a live session or grub rescue to get to a command line.

It MIGHT work to just do chown -R alex:alex /home/alex but if it does not you pile another problem onto this problem.

So the procedure would be ...

From command line:

Start by copying (not moving) everything back to /home/mary.

Confirm if logging into mary works. If not do a chown -R mary:mary /home/mary and try again.

If it does work remove /home/alex (so actual rm and not deluser since there is no user alex, only a directory) and proceed with the method listed above.

Also have a look at .xsession-errors. That is where errors are logged.

  nope. You mount your partition. It will be in /media/disk name/home/ @mzlle add any questions or problems you have into the question. I'll get a notification when you do and will add to my answer if I can :) Another thing: you can mount the disk and then copy files to a 2nd usb disk if need be. Then you have those files saved.
