@JoeA-B said in PkgConfig cannot find directfb:

Why not link? I am adding a module to a full operating system and cannot control the rest of the configuration

still a simple -ldirectfb parameter should work on all systems, when the plugin is in a default lib directory (which /usr/lib/x86_64-linux-gnu is btw for example on Debian/Ubuntu)

@SGaist Thanks.

Hi and welcome to devnet,

In order to have a window manager you might want to take a look at the wayland module

Hope it helps

@tomma

Thanks a lot! That was great input.
While reading about uinput the idea of writing to the event itself instead crossed me.
I implemented a function that generates the various (basic) events of a touch screen and writing it directly to event0.
It works perfect so far.

That doesn't really help. I know the difference between the 2 devices.
The issue seems to be in the path and maybe the resulting timing Qt (QWS to be more precise) gets the XY position compared to the path over which it gets the click events. This seems not to travel the same way from DFB to QWS.
Still have no solution for this.
