Enter key stopped working in ubuntu after updating gsettings

Question

I was trying to setup my zsh to make different binding for enter and ctrl + enter, and faced the following problem.

Following instructions from here I executed these commands in the terminal:

gsettings set  org.gnome.settings-daemon.plugins.media-keys custom-keybindings "['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/']"
gsettings set  org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ name 'File Browser'
gsettings set  org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ command 'nautilus'
gsettings set  org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ binding '<Enter>'

And after log-out and log-in my enter key has stopped to work at all. Now it works only in the sign-in screen. I've tried to revert the changes with the following command:

gsettings reset org.gnome.settings-daemon.plugins.media-keys custom-keybindings

But it didn't help. Now when I open the terminal and type command showkey -a, after which I make the following sequence of key combinations: enter, ctrl+enter, alt+enter, the command emits the following text:

^[   27 0033 0x1b
^M   13 0015 0x0d
^[^M     27 0033 0x1b
     13 0015 0x0d

But earlier it generated the same symbol ^M for all three. Please help me return to the default settings.

I've tried to revert the changes using gsettings reset command, I expected that my enter key will be boud to ^M again, but it didn't help. Everything is the same.

Also tried:

gsettings reset-recursively org.gnome.settings-daemon.plugins.media-keys
sudo dpkg-reconfigure keyboard-configuration

Nothing helps.

The problem was caused by the file $HOME/.XCompose, which I configured to redefine Ctrl + Enter combination. Howerver, as it turns out, ibus doesn't support key modifiers (Ctrl in my case), and this file just reassigned Enter.

include "%L"
! Ctrl <Return> : "\037" # reassigns Enter instead of Ctrl+Enter
