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 screen, then after login it stops working after "one" touch. Then closing the lit and the touchscreen works fine again. I have an XPS-15-9530 Dell laptop. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1876991 Title: Touchpad started appearing both as a touchpad and as a mouse input devices after upgrade to 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1876991/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
