I was typing a text when my touchpad stopped working. After surfing on the web to try to fix the error, I ran
xinput list and here is the output :
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Logitech USB Optical Mouse id=10 [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)] ↳ HD Webcam: HD Webcam id=11 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)] ↳ MSI WMI hotkeys id=13 [slave keyboard (3)] My touchpad seems to be not detected as it does not appear in the output.
Thanks for your help.

Two possibilities:
- Something physically wrong with touchpad, e.g., a connector unpluged due to vibration, or water got into it.
- Software issues, e.g., a missing or bad driver, or the device was disabled.
In your xinput list output, there is no entry for a touchpad, e.g.,
SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
- To see if that device is connected, create a Live Ubuntu Flash USB Stick and boot from it. Run
xinput listand see if the touchpad shows. * If the touchpad is not in the list, the issue is likely in hardware, and you should check for loose connections or a bad touchpad. - If the touchpad is present in the list, the issue is likely in software, so note the touchpad make and model. Then reboot from the HDD or SSD and try reinstalling the drivers shown using Terminal or the Syanaptic Package Manager.
