I thought that logging as root was prohibited by GUI display managers.

You need to unmount /home first. If you're logged as root, it should work.

What do you call "command line interface for root" ? Single user mode ?

I hope you reran the resize2fs command successfully before doing this.
Otherwise you just ruined your /home filesystem.
