I installed the Cinnamon Desktop Environment on My Ubuntu 21.10 OS. After that whenever I open a text editor and press Ctrl + . it prints e. It just toggles if I press it multiple times. I tried different Desktop Environment like KDE, it behaves exactly same. When i remove the DE and use Ubuntu as is, the problem goes away !

I am quite unsure why this is happening , bit of help on this will be really helpful, Is there any restriction in terms of using different Desktop Environments on Ubuntu?

OS: Ubuntu Cinnamon 21.10 x86_64 
Kernel: 5.13.0-30-generic 
Shell: bash 5.1.8 

DE: Cinnamon 4.8.6 
WM Theme: Fluent-round-compact (Yaru 
Theme: Fluent-round-compact [GTK2/3] 
Icons: Fluent-dark [GTK2/3] 
Terminal: gnome-terminal

  • I was curious as it was not just with Mint, other distros had the same issue, but thanks for the clarification though. – Siratim Mar 11 '22 at 13:18

What you're seeing I believe is part of a means for quickly inserting emojis with the ibus input method framework. There's some details about it here and here, including I think a way to disable it.

Addition : Just for easy reference added shortcut change the process.

  • Search for IBus Preference
  • Go to Emoji tab
  • Change the Emoji annotation to anything else.
  • Click Apply

  • Normally, in GTK applications, Ctrl+. should display a window to pick an emoticon. In other applications, e.g. Firefox, it does nothing. So here something else seems to happen. – vanadium Mar 11 '22 at 19:31
  • @frabjous and @vanadium Thank you, those links do have good information, and i was able to change the default shortcut for emoji from `ibus-preference`, things seems to work out. – Siratim Mar 12 '22 at 04:03
  • For me searching for `Ibus Preference` didn't bring up this dialog, but you can get to it by typing in a terminal: `ibus-setup`. Alternatively setting an empty shortcut with `gsettings set org.freedesktop.ibus.panel.emoji hotkey "[]"` also worked for me. – mdev Oct 31 '22 at 16:33
