I apologize in advance : I have access to only 2 tablet brands, hopefully your tablet works like mine.

Please note that the tablet need to be initialized before the software is launched.

Windows

1. uncheck customized mapping
2. make sure the monitor settings match your configuration
3. restart

If it still doesn't work, it may be on my side. Post about it.

Linux

1. make sure the monitor settings match your configuration
2. use the means at your disposition on your distro to get how the tablet is mapped to the screen, and fill the related settings
3. set the monitor offset to (0,0) : it should only be needed on windows

where I get the mapping info  on manjaro kde :

Wacom tablets should not be a problem.

There is  probably some configuration required to get other tablets to work.

In the case of a XP-Pen Deco 01 V2, for example :

edit /etc/X11/xorg.conf.d/50-tablet.conf

Section "InputClass"    
    Identifier "Tablet"    
    Driver "wacom"    
    MatchDevicePath "/dev/input/event*"    
    MatchUSBID "28bd:0905"
EndSection

then restart

If that doesn't work, feel free to play around with the values, or make a post about it.
