And if later you install a new version of MATE with the problem corrected, the launcher should continue to work normally without changes. The beauty of it is that you are not changing anything in your system, only creating a launcher. As mate-terminal is a MATE application, you don't need to select ¨Application in Terminal¨ in the Type field, just ¨Application¨, so the launcher itself doesn't open a terminal (but mate-terminal does), and whether xterm is installed or not does not affect anything. (where command is the command you want to launch) in the Command section of the launcher should do the trick. Code: Select all mate-terminal -e 'command'
