Comment 3 for bug 1845332

Thank you so much for the quick response!

I switched "Keyboard input method system" to "XIM" as you suggested and now everything works fine.

However, I have a few questions about it.

>> That wiki page you referred  to was last edited 11 years ago and is obsolete to a large extent.

Is it possible to contact someone to ask to update this page?

>> Today, on an Ubuntu system, it's normally GTK (not IBus, so I'm closing this bug report) which deals with rules in the ~/.XCompose file.

On my Ubuntu 18.04 "Keyboard input method system" gives me options IBus, XIM and none.

Is there any known advantage of choosing IBus there?
(I am trying to understand why XIM is not a default.)
