I'm running AutoKey on Ubuntu 18.04, I added it to the startup applications, but I don't want its window pops up after starting my computer, can I make it launch in the background?
In case you are using Gnome's "Tweaks" tool to put it into autostart: Edit
~/.config/autostart/autokey.desktop to remove the
-c flag from the
Exec line. It should then look like this:
Comment=Program keyboard shortcuts
(You can also just create that file without using any GUI tools.)
