You did not specify the path/name of the config file.
There's nothing active in that file. Did you place comment marker( # ) on some of the lines?
One might try activating the
by removing the comment marker. ...but I think that is the default because typically config files will have the default values commented as those are, if the default values are present.
If true, the
CTRL+SPACE key combo should deactivate the virtual keyboard window.
Unless you inserted comment markers, of course.
Chances are that once deactivated, it will not appear again until activated with a trigger-on combo. I had a similar issue with another program years ago. Ultimately I uninstalled the program as I did not need it but in the interim all I had to do was deactivate it.
If the program is not needed, uninstall it.
To determine what program supplies the config file do
pacman -Qo /path/to/config/file/name
replacing ''/path/to/config/file/name'' with the actual info of course.
Once the program is known, just use the standard uninstall method for it.
