On my Dell Latitude 4590, the two buttons below the Touchpad are not functional.

$ xinput list

The strange thing is that no event is generated when I click on the two buttons below the Touchpad which was checked using xev.

  • Run the Dell hardware diagnostics from a bootable USB key and see if this is a hardware problem (diagnostics) or software driver issue (no hardware issue).

  • Try Dell Support and see if they can supply a Linux driver. See if Bluetooth works and use a Bluetooth mouse (I do this). Get a LogiTech Mouse with an RF USB key. Try these things.

  • So, you suggest that the PixArt USB Optical Mouse actually connected may cause the problem ? unplug and hotplug does not resolve the problem, I will reboot without the plugged mouse.

  • I was suggesting an external Mouse. But if one is connected, yes, temporarily remove it , restart and test.
