Do you really need that bamf = application matching framework ? I try to understand what it does, but seems to be related to deepin, gala, mate-applet, ukui-menu, wingpanel … all the fancy is put out there this days …
But i guess you installed a lot of that fancy stuff on top of it.
Is it properly configured with the drivers and such? If not, take a look here
but i never heard of a tablet to do that to a system.
