I also found a trick how to make it work again, you close the lit of my
XPS15 laptop and open is again. Then it works again.
(Maybe helps some people who really need this to work ASAP for
development)
Maybe it has something to do with the Gnome Session? As the touchscreen
works in the login scree
Im not so deep into the technical part but:
Touchscreen does work in the login screen perfectly. After you log in the
touchscreen works for few seconds and after that stops working.
I use the touchscreen for application development testing. So hope this
get solved. Anyone a quick fix for this?
