My touchscreen device does not scroll on touching it with one finger, which is desired, but only when touching it with two fingers.
- Linux kernel 4.9.81-intel-pk-standard
- custom distro via yocto
- Xserver (X.Org X Server 1.19.3)
- QtWebEngine (Qt5.9)
- I guess it is an Xserver Problem, since it's got to be Xserver or the web stuff, but I can rule out the web stuff because I can access the UI remotely from a desktop PC's chrome browser, use chrome's inspect function to simulate a touch device and scroll the UI with the simulated (single finger) touch.
- The two fingers need to be at least about 2cm apart so that scrolling works (this might be irrelevant)
