Estou executando o Ubuntu 19.10 em um Dell Inspiron 13 7000 2 em 1 Black Edition (7391). O laptop vem com uma caneta muito boa, a Dell PN350M Active Pen, que infelizmente não funciona no meu sistema. Uma pequena pesquisa na web revela que a caneta usa o Microsoft Pen Protocol para emparelhar com um laptop em vez de Bluetooth. Eles são suportados? O Google me deixa sem respostas.
EDITAR:
Abaixo está uma saída atualizada do xinput. Há algo suspeito aqui, em particular a coisa “DESCONHECIDA”.

Consegui criar um driver python usando as bibliotecas evdev e libevdev. Estou criando um dispositivo virtual e simplesmente passando os eventos que encontrei na caneta. Ele está trabalhando com eventos de pressão e rastreamento, mas não consegui fazer os botões funcionarem.
Basta copiar isto e marcá-lo como executável e você verá um dispositivo chamado "Caneta Personalizada" que deve funcionar. Além disso, para torná-lo perfeito, adicionei-o ao gnome-session-propertiespara que ele execute o script na inicialização.
Espero que isto ajude!

tenho a mesma pergunta. Estou na prata de 15 ". Teve uma ideia de que você poderia usar drivers wacom que usam esse protocolo? Mas fora isso, você teria que colocar as mãos nos drivers mpp, embora não tenha certeza de onde
