Hi there! When I try to switch to another language, this change is not displayed on the XFCE panel automatically. My key combination to switch layouts is Alt+Shift. I’ve also tried to restart the panel via:
xfce-panel --restart
It didn’t help. I have XFCE 4.16 installed. How can I find the source of the issue?
Does that mean you are using Xubuntu 22.04?
Or did you install XFCE some other way?
Yes, it does, I use it.
@emilygraceseville7cf Welcome to Ubuntu Discourse 
In a terminal check this:
echo $XMODIFIERS
Expected results are IBus, Fcitx or XIM
If the command produces nothing, it may be that your input methods are not set up correctly.
Which language is the default and which other languages do you want to use?
Is it displaying language, or is it displaying keyboard layout?
What method are you using to display it on the XFCE panel?
Have you found anything that does help? Or is the panel always stuck showing one particular (language / keyboard layout) regardless of anything you do after switching?
It outputs: @im=ibus.
Keyboard layout like EN.
I’ve added Status Tray Plugin item to it.
It’s stuck for some reason. What interesting is that until my keyboard layout is EN I can’t launch applications I have set up keybinding for like Ctrl+Shift+A, they don’t work when other layout is active. I have no clue whether it’s expected or not.
Ofc correct me where I misunderstand something please. 
Will you try this:
xfce4-panel --quit
pkill xfconfd
xfce4-panel &
Run one line at a time.
I’ve tried, it didn’t help, now I can type just in English… TBH I can’t track what caused it, at some moment it stopped switching between languages completely even before running these commands you provided. Keyboard shortcuts also stopped working to launch applications.
Status Tray is Xfce’s way of presenting desktop-environment-independent tray icons for currently-running programs that have such icon. What program is your keyboard layout icon coming from?
