Bug ID: 414964
Summary: Touchpad stopped working after kernel update to
4.15.0-72
Product: neon
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: general
Assignee: neon-b...@kde.org
Reporter: tomas.teije...@gmail.com

Target Milestone: ---
SUMMARY
After updating my neon installation to plasma 5.17.4 with kernel 4.15.0-72, the
touchpad stopped working completely. The synaptics touchpad is still recognized
as an input device in `xinput`, but it does not send any X event. If I boot
with the previous kernel, 4.15.0-70, the boot screen shows neon 5.17.3, and
everything works perfectly. I'm not sure if it is a kernel bug, an Ubuntu bug,
or a Neon bug.
My laptop is a Dell XPS 13 9333.
STEPS TO REPRODUCE
1. Boot KDE Neon
2.
3.
OBSERVED RESULT
The touchpad does not work at all. No motion, no click, no scrolling.
EXPECTED RESULT
The touchpad should work as always.
