I'm using a convertible (Thinkpad X200T, Manjaro Xfce) and it has stylus input though no finger touch. Stylus input as such is perfectly working, I can control the mouse cursor and do a right and left mouse button click.
However, since there is no mouse wheel, I cannot scroll in application in a simple way. For Firefox there is an extension for exactly this task, ScrollAnywhere. However, most other apps don't offer "drag to scroll" functionality.
I read that this is dependent on the toolkit in use. GTK3 offers this while GTK2 does not: https://ubuntu-mate.community/t/touchscreen-support-for-atril/14323 However, if I'm not mistaken, the atril package from the community/ repo is build against GTK3 but still I cannot scroll by dragging and don't see a setting to enable this scrolling mode. Even Evince (which is only available for GTK3) doesn't work this way.
So I wonder is some further configuration is required or if I need to wait for Xfce GTK3 to land in the repos?
Thanks for any input and a happy new year!
