Hi @BWaves2019, I wish I had an answer. This issue has been around for quite some time and appears in this 4-year-old related topic.
Summarizing 20.04...
- Executes /usr/bin/x-terminal-emulator
- This is a link to /etc/alternatives/x-terminal-emulator
- This is a link to /usr/bin/lxterm
- This is a script to run xterm version by locale.
So it turns out there are many places to hack it. I invite a developer to comment on the best way and if this might get fixed someday.
