Public bug reported: I upgraded my Ubuntu 18.04 with the `apt upgrade` command, and the kernel upgrade to 4.15.0-72. After a reboot, the touchpad stopped working. And the external USB mouse kept working fine.
Looking for this issue, I found these reports about similar problems (https://sangams.com.np/fix-ubuntu-18-4-touchpad-not-working-properly/ and https://askubuntu.com/questions/1041820/touchpad-not-working-on- ubuntu-18-04), and I checked the package `xserver-xorg-input-synaptics` wasn't installed. Then I tried to install with the command: `apt install xserver-xorg-input-synaptics`. I rebooted the computer, but the problem continues. After I ran a diagnostic test with BIOS from Dell Notebook, and on interacting with the diagnostic system, I was able to use the touchpad without problems. Then I suppose this problem is from SO kernel upgraded. ========================= Follow some info's system: $uname -a Linux myinspiron155547 4.15.0-72-generic #81-Ubuntu SMP Tue Nov 26 12:20:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux $ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Synaptics s3203 id=11 [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)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ Integrated_Webcam_HD: Integrate id=10 [slave keyboard (3)] ↳ Dell WMI hotkeys id=12 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] ** Affects: xserver-xorg-input-synaptics (Ubuntu) Importance: Undecided Status: New ** Tags: synaptics touchpad ** Description changed: I upgraded my Ubuntu 18.04 with the `apt upgrade` command, and the kernel upgrade to 4.15.0-72. - After a reboot, the touchpad stopped working.
