Barrier (Synergy) with Wacom Intuos BT M

I am looking for a more ergonomic pointing device. Thus, I borrow my daughter’s Wacom Intuos BT M drawing tablet a try.

Fedora 33 Gnome seems to recognize it out of the box, and the gnome-control-center Wacom interface show it properly. With RHEL 8, it also works as a mouse, but for Gnome to see it, I needed to install the following:

yum -y install libwacom

I mainly use KDE, so I also install

yum -y install kcm_wacomtablet

Gnome did not have the UI to bind the tablet button to mouse button like Mouse button 4 (Scroll Up), nor does it handle key combo binding properly. For example, Ctrl-Win-Left is recognized as Primary-Super-Hyper-Left; KDE, however, does support Mouse button 4~7 so I bind inner left tablet button as button 5 and inner right tablet button as button 4.

I use barrier, a keyboard/mouse sharing utility intensively. So I would also like to see how barrier handles Wacom. Unfortunately, with absolute position mode (the default), the pointer insisted it needed to be in the left edge of the client, I need to use barrier switchInDirection keyboard short keyboard to get away.

I also tried related position mode which make the tablet work more like a giant touchpad. It kinda of work, as the pointer in client act normally. However, that mode is very unpleasant to use, as I need to fully away the distant between stylus and tablet. Basically:

State 1: Stylus touch tablet: Mouse Left button click
State 2: Stylus hover tablet: Mouse move
State 3: Stylus leave tablet: Mouse No action

Switching between State 2 and State 3 is required for related position to work, that is unpleasant.

I tried USB on server, and BT on client as well, but Intuos only support single connection, that is, you have to disconnect USB to use BT, so no single-button-toggle target computers. 😦

Verdict: I would not a recommended Wacom over Barrier/Synergy setup, unless You are OK with relative position mode.
