Touchpad disabled because a mouse is plugged in (when not really)

I’ve got this XPS15 9560 laptop whose touchpad is not working as it is not responding to any input.
So far, at least I realize that the laptop says it always detects a plugged in mouse even when nothing is plugged in except the power cable. At reboot, a notification would say “touchpad is disabled because a mouse is plugged in” at reboot with or without a mouse connected.
The following is the screenshot of the touchpad setting page:

cat /proc/bus/input/devices

There’s a dmesg that says

[1.816739] psmouse serio1: synaptics: Your touchpad (PNP: DLL07be PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to

I tried adding psmouse.synaptics_intertouch=1 at kernel option using the yast2-boot loader but still no go.

There’s probably something that tells your desktop software that a mouse is plugged in. I use a wireless mouse, and as long as the wireless dongle is plugged it, it will disable the touchpad – even if the mouse no longer exists.

I see that the setting doesn’t show up for you. That’s a known bug (KDE bug 415364). You can remove that setting by manually editing


Hi, many thanks for the answer. At least I can use touchpad now after manually editing touchpadrc to disable the auto-disable feature.
What still puzzles me is: what mouse is it detecting when everything is unplugged from the ports of the laptop?
I do use a wireless logitech mouse with a dongle, but the dongle has already been removed when the touchpad is disabled.
Here’s how I reproduce the problem:

  1. Shutdown laptop.
  2. Unplug everything
  3. Boot up, and a notification would come up saying “touchpad is disabled because a mouse is plugged in”.
    Any clue on how to solve this?

It’s a bit hard to guess.

I’m glad you were able to get around the problem by editing that file.
