I have Dell XPS 15 9530. In it, I had a Debian Jessie virtual machine (vmware) inside a Windows 10 host. The touch screen was working fine.
After upgrading to Debian Stretch, the touch screen doesn't work properly anymore. The mouse position doesn't match the touch position. How can I tackle this problem? I don't even know where to start.
I'm using SDDM as an xserver manager and KDE Plasma.
I found out that if I connect the touch screen to the guest machine as a USB device (and consequently, disconnect it from the host), it works fine. While this "works", it's horrible, because every time I have to switch from host to guest or vice versa, I have to switch that option and deal with drivers in Linux.
