After Ubuntu Budgie system upgrade from 20.04 to 22.04 the correct system keyboard (in my case Bulgarian traditional phonetic - 'асдф') did not work but the layout was replaced by English (US) - 'asdf' despite it indicates Bulgarian. When Bulgarian input source is removed and added again the characters display correctly ('асдф') until the next logging out and in when again English (US) displaces Bulgarian layout.
I am using English (US) as default layout.
I tried to see if I can see any message appearing when run settings from terminal using 'gnome-control-center' but nothing. fcitx Is not installed.
And one more thing you may ask about:
cat /etc/default/keyboard
XKBLAYOUT="us,bg"
XKBVARIANT=",phonetic"
BACKSPACE="guess"
XKBMODEL="pc105"
XKBOPTIONS="grp:lctrl_lshift_toggle,grp_led:scroll"
sudo dpkg-reconfigure keyboard-configuration
this makes system remember what you select, I hope. – Sadaharu Wakisaka May 11 '22 at 01:10sudo
is a command that the program open as a root user. – Sadaharu Wakisaka May 11 '22 at 21:25
