I use Ubuntu 20.04. I have installed Terminator through
aptitude and configure it as my default
update-alternatives. Now I can correctly open Terminator from the right-click menu on the desktop. But there are some other problems:
The terminal opened through the right-click menu on the file manager is still gnome-terminal. It does not appear to be switched properly.
I added Terminator to my favorites. When I first open the Terminator of the favorites, and then open the Terminator of the desktop right-click menu, they can be correctly stacked on the taskbar; but when I first open the Terminator of the desktop right-click menu, a new Terminator icon will appear in the taskbar. It cannot be added to favorites, nor can it be stacked to the original Terminator icon.
How can I solve these two problems?
