[SOLVED] UC-Logic TWHA60 Evdev Tablet Misconfiguration

Hey folks.

Here's the DIGImend link for the tablet I have: https://digimend.github.io/tablets/UC-Logic_TWHA60_v3/

The problem I'm having is that it's not working like a tablet. It's working like a trackpad. I.e. it only moves the cursor when it's pressed against the tablet, and I have to drag it. I'd like it to be more of an absolute positioning system.

I've spent a little while troubleshooting this, but I'm mostly spinning my wheels. AFAIK I don't have any custom xorg settings that should touch this. Any help you folks have is appreciated. I know my way around the computer and I have a vague idea of the utilities surrounding this, but I'm not sure what snippets anyone would want, but I can definitely post logs.

The one thing that strikes me as weird is that it shows up a whole bunch of times (particularly twice as Mouse/Pen) in xinput.

$ xinput
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Logitech Gaming Mouse G402              	id=8	[slave  pointer  (2)]
⎜   ↳ Logitech Gaming Mouse G402              	id=9	[slave  pointer  (2)]
⎜   ↳ UC-LOGIC TWHA60 Consumer Control        	id=12	[slave  pointer  (2)]
⎜   ↳ UC-LOGIC TWHA60 Pen                     	id=14	[slave  pointer  (2)]
⎜   ↳ UC-LOGIC TWHA60 Mouse                   	id=15	[slave  pointer  (2)]
⎜   ↳ UC-LOGIC TWHA60 Pen                     	id=16	[slave  pointer  (2)]
⎜   ↳ UC-LOGIC TWHA60 Mouse                   	id=17	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ Dell Dell USB Keyboard                  	id=10	[slave  keyboard (3)]
    ↳ UC-LOGIC TWHA60 System Control          	id=11	[slave  keyboard (3)]
    ↳ UC-LOGIC TWHA60 Keyboard                	id=13	[slave  keyboard (3)]

TL;DR: tablet acts like a trackpad, would like it to be a tablet, can post xorg conf files, logs, &c.

Sorry to double-post, but I figured I'd post what I know for the benefit of others.

This is a kernel module bug. It's basically fixed upstream. So, if you really want it to work right now, you can install the latest master drivers:

Thanks!
