I had second display connected to my laptop before, Google Chrome wants to stay there often. I tried to restore the second display without having the second monitor connected to the laptop (because I wanted to use Google Chrome, Quit does not help). I pressed FN-F9 and then FN-F8 after which I lost the communication to touchpad. Keyboard works fine. I restarted the system many times but still the problem occurs. I do not understand why.

I tried to restore the problem by pressing again the FN keys but no resolution. I want to restore the working touchpad on Wayland Debian.

Lost communication on the touchpad in Wayland now. No touch works. No pressing of the touchpad works.

I can log back to X11 where the touchpad works.

Testing Joshua's proposals

  1. Do gksudo gedit /etc/default/grub, edit GRUB_CMDLINE_LINUX_DEFAULT="quiet i8042.nomux=1 i8042.reset", sudo update-grub successfully and reboot but output still failure with touchpad.

  2. Do gksudo gedit /etc/default/grub, edit GRUB_CMDLINE_LINUX_DEFAULT="i8042.nomux=1 i8042.reset", sudo update-grub successfully and reboot but output still failure with touchpad.

OS: Debian Stretch 9.1
Hardware: Asus Zenbook UX303UA R4028T
Touchpad: FocalTechPS
Window manager: Gnome 3.22 on Wayland 1.12


I had an issue similar to that and was able to find a solution on the Arch Wiki. It seems like 4.1 and 4.3 would be good, easy things to try. For me, it was actually adding these kernel options:

i8042.nomux=1 i8042.reset

  • You can do that; whatever you're comfortable with. You'd add the parameters to GRUB_CMDLINE_LINUX_DEFAULT then run sudo update-grub. – Mountainerd Oct 20 '17 at 5:33
  • If that's a copy/paste from your grub config, it may fail with 'queiet' (it should be 'quiet'). – Mountainerd Oct 20 '17 at 5:40
  • update-grub fails or the touchpad still doesn't work after reboot? – Mountainerd Oct 20 '17 at 5:44

    I think I have a Zenbook in the office. I'll get Debian up and running and see if I can recreate the issue tomorrow. – Mountainerd Oct 20 '17 at 5:50
  • I haven't been able to recreate the problem you're having yet, no. I've tried, but the behavior simply isn't happening on my end. – Mountainerd Oct 23 '17 at 4:22
