The problem

When I try to use my laptop touchpad, nothing happens. It also does not respond to clicks. The keyboard works fine.

Workarounds

Using a usb mouse works just fine

My system

Acer Aspire 5

Pop!_os 20.10 (I started with 20.04 and upgraded last night. Didn't fix)

> uname -a
Linux pop-os 5.8.0-7642-generic #47~1614007149~20.10~82fb226-Ubuntu SMP Tue Feb 23 02:59:01 UTC  x86_64 x86_64 x86_64 GNU/Linux

It does seem to be recognized though...

It is also showing up under Virtual core pointer:

  • There is often a hardware switch for touchpads have you checked that usally it is something like alt-F5 I know is simple and stupid but need to ask. Also verify xserver-xorg-input-synaptics is installed. Also some bios have a touchpad mode in them that needs to be set. – Jason Croyle Feb 27 at 17:25
  • Élan should work in thé same way as synaptic, please check m'y answer unix.stackexchange.com/a/337218/153195 – GAD3R Feb 27 at 18:28
