This is the /etc/X11/xinit/xinitrc.d/99-zzz-me-last.sh file I use
with my Kensington Expert Mouse:
#!/bin/bash
#
# Setup the mouse buttons for drag lock
#
xinput --set-button-map \
'Kensington Kensington Expert Mouse' \
1 8 3 4 5 6 7 2
# Enable drag lock
#
xinput --set-prop --type=int --format=8 \
'Kensington Kensington Expert Mouse' \
'libinput Drag Lock Buttons' 2 1
This renumbers the buttons so I can make the top left
one be drag lock (just personal preference) then
sets it to always be a button 1 drag (there are other
ways to configure it so you can say which button to drag,
but that needs two clicks). With this setup I click
the top left button and I'm now dragging, click it again
and I stop dragging.
I don't know if wayland has any equivalent, they last time I
tried to find something it was utterly lacking any way to
configure stuff at this level (or even distinguish between
multiple pointer devices).
