Bookworm: IBus input method preferences frequently forgotten

[Christian Gelinek <cgelinek@radlogic.com.au>]

Hi all,

I'm running the XFCE desktop on Bookworm.

Via the IBus Preferences ("ibus panel" under Status Tray Items) dialog 
under Input Method, I like to add the "English (intl., with AltGr dead 
keys)" input method as a default to use across the whole system. Also, 
to prevent accidental switching, I remove the default "English (US)" 
input method and on the General tab, I delete the "<Super>space" 
keyboard shortcut to switch input methods.

I have done this a number of times already but often after re-booting my 
system, the old settings are back, including the "English (US)" input 
method and the "<Super>space" keyboard shortcut.

How can I find out what the problem is and make my preferences "stick"?

Thanks for your time!

Christian
