Public bug reported:
I am running Ubuntu 18.04.3 on a Dell XSP12 laptop. After an automatic
kernel update from 4.15.0-70-generic to 4.15.0-72-generic, my touchpad
stopped working. (The mouse pointer is not moving, and I cannot click.)
The touchpad is still working when I start up with the older kernel.
I think it's a Synaptics touchpad. The output of 'xinput list' when
running either kernel is as follows:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ATML1000:00 03EB:842F id=11 [slave pointer (2)]
⎜ ↳ Synaptics s3203 id=12 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=16 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Integrated Webcam: Integrated W id=9 [slave keyboard (3)]
↳ Intel Virtual Button driver id=10 [slave keyboard (3)]
↳ Dell WMI hotkeys id=13 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)]
↳ DELL Wireless hotkeys id=15 [slave keyboard (3)]
