The problem might also involve udev, as by these lines: [ 800.429] (II) event5 - NextWindow Touchscreen: is tagged by udev as: Tablet [ 800.429] (EE) event5 - NextWindow Touchscreen: libinput bug: missing tablet capabilities: btn-stylus resolution.Ignoring this device. [ 800.429] (II) event5 - NextWindow Touchscreen: device is a tablet [ 800.429] (II) event5 - failed to create input device '/dev/input/event5'.
udev should recognize as TouchScreen, not Tablet. On previous Xorgs, evdev was used, not libinput. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1761773 Title: Touch Screen stop working on 18.04 beta1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1761773/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : email@example.com Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
