Screen tablet Huion Kamvas Pro

I have a Huion Kamvas Pro screen pen tablet that actually works... just not at first boot.

At boot it is seen just as an additional monitor and to have the pen working I have to do:

rmmod hid_uclogic
modprobe hid_uclogic
xsetwacom set "Huion Tablet_GT1602 stylus" MapToOutput DisplayPort-2

Sometimes also rebooting is enough to make it work.

Is it some kind of race condition where something gets initialized before something else? Is there anything I can do to fix it?

Looking at dmesg everything seems to be recognized correctly at boot but still doesn't work until I force reload the module.

The only config file I had to do is this

cat /etc/X11/xorg.conf.d/40-tablet.conf 
Section "InputClass"
        Identifier "Tablet"
        Driver "wacom"
        MatchDevicePath "/dev/input/event*"
        MatchUSBID "256c:006d"
EndSection

It was actually working a few kernels ago, unfortunately I haven't used the tablet for a few months so I'm not sure what kernel version it stopped working.

Are you seeing other video output(s) in dmesg?
Try force-disabling the output you DON'T want, using this kernel parameter:

video=UNWANTED-OUTPUT:d

Replace UNWANTED-OUTPUT with the correct one you need to disable.

like unused/wrong ones? none that I can tell. Also looking at xorg log everything seems fine, no errors and the tablet is recognized correctly

Re: Screen tablet Huion Kamvas Pro

it actually is a monitor, so that is an expected behavior (sorry unless I'm missing something)

I made a wrong assumption, sorry.

OK
