I have an ASUS zenbook running Ubuntu 18.04, and everytime I opened up my laptop the touchpad stopped working, so I would open up the terminal and run this:
sudo rmmod i2c_hid
sudo modprobe i2c_hid
However, recently, even this stopped working. Diagnostics tools tell me that the touchpad isn't even recognized.
Gnome Shell Version: 3.28.3 Touchpad Indicator Version: 31 Touchpad(s): No Touchpad detected. Synclient: Not found or used on your system. Xinput: Is installed. Switch Method: XInput
So I tried reinstalling some things
sudo apt install --reinstall xserver-xorg-input-synaptics
And I have the most recent update for Ubuntu 18.04.
Here is what xinput shows
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [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)]
↳ Asus Wireless Radio Control id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Video Bus id=9 [slave keyboard (3)]
↳ Power Button id=10 [slave keyboard (3)]
↳ Sleep Button id=11 [slave keyboard (3)]
↳ USB2.0 HD UVC WebCam: USB2.0 HD id=13 [slave keyboard (3)]
↳ Asus WMI hotkeys id=14 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)]
Any suggestions? Thank you.
