I'm trying to use xdotool to configure touchpad gestures on Ubuntu 18.04 with Gnome.
This works fine:
xdotool key ctrl+alt+Down
xdotool key ctrl+alt+Up
does not change workspaces and instead seems to output some extra characters to the terminal.
I also attempted to use the serial values, and the keysym values output by the
xev command and the behavior is identical.
