Description Russell Haley 2026-01-01 17:35:46 UTC 
SUMMARY

Can only enter unicode with ctrl+shift+u when Virtual Keyboard is enabled and set to Ibus Wayland

STEPS TO REPRODUCE

1. Have the default virtual keyboard setting, Maliit.
2. Open a non-GTK app with text entry, like kwrite or zed editor.
3. Press ctrl+shift+u
4. Change vitual keyboard to "Ibus Wayland" and click the widget to enable the virtual keyboard
5. Press ctrl+shift+u in the non-GTK text field again.

OBSERVED RESULT

Nothing happens at step 3.

At step 5, Underlined "u" appears in text entry field, ready for direct unicode codepoint entry. For example, ctrl+shift+u 394 -> Δ, b0 -> °, etc.

EXPECTED RESULT

Default configuration behaves as in step 5.

ADDITIONAL INFORMATION

This is kind of a duplicate of 103788, but I am reporting it against the part of the software stack that seems to be best placed to resolve the problem, with a more searchable title that describes how to work around it locally.

That makes sense since this is an IBus-specific feature. :) 

Unfortunately right now input methods are mutually exclusive. You can use IBus or Maliit, but not both at the same time.

Ideally this would change in the future, but it's a multi-year project due to the technical complexities involved.
