Touchpad started appearing both as a touchpad and as a mouse input devices after upgrade to 20.04

[Serhiy]

It was working perfectly on 18.04 with 5.3 kernel but after upgrade to 20.04 it's becoming disabled because there is a "mouse" attached which is the same touchpad detected incorrectly, xinput --list showing both

⎜ ↳ MSFT0001:00 06CB:7E7E Mouse id=11 [slave pointer (2)]
⎜ ↳ MSFT0001:00 06CB:7E7E Touchpad id=12 [slave pointer (2)]

The first line was definitely not present before, I know it because I use it when in openbox session.

There is also a number of questions on AskUbuntu that look like results of the same problem at first glance:
https://askubuntu.com/q/1231873/20275
https://askubuntu.com/q/1235067/20275
https://askubuntu.com/q/1234975/20275

and two global search results for the same touchpad model ("MSFT0001:00 06CB:7E7E Mouse") that show the same problem in unrelated contexts:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=953405
https://bbs.archlinux.org/viewtopic.php?id=240723

I also have these errors in kernel log, may be related, weren't present previously:

psmouse serio1: Failed to enable mouse on isa0060/serio1

After removing xserver-xorg-input-libinput third input device appears, a 'PS/2 Generic Mouse' and both mice become evdev devices so it doesn't look like a libinput problem.

[aeronutt (aeronutt)]

I have a similar problem in Ubuntu 20.04
Dell Precision 5510.

The touchpad randomly ignores 'clicks'. (both mechanical and touch clicks).

I get similar results from xinput --list:

$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=16 [slave pointer (2)]
⎜ ↳ DLL06E5:01 06CB:7A13 Mouse id=11 [slave pointer (2)]
⎜ ↳ DLL06E5:01 06CB:7A13 Touchpad id=12 [slave pointer (2)]

AND, have similar errors in the boot and shutdown log files:

psmouse serio1: Failed to enable mouse on isa0060/serio1
psmouse serio1: Failed to enable mouse on isa0060/serio1
psmouse serio1: Failed to deactivate mouse on isa0060/serio1: -5

Status changed to 'Confirmed' because the bug affects multiple users.

[aeronutt (aeronutt)]

Update on this issue.

Ubuntu LTS 20.04 has this touchpad problem, and uses xinput version:
xinput version 1.6.3
XI version on server: 2.3

However, Kunbuntu 19.10 does not have this touchpad problem, but uses same xinput version:
xinput version 1.6.3
XI version on server: 2.3

This may not be solely an xinput bug, should I report this elsewhere?

Using Ubuntu 20.04 with this bug is difficult.

[Serhiy (xintx-ua)]

Can you compare xserver-xorg-input-synaptics versions?

[Herman Willems (hermanwillems)]

Im not so deep into the technical part but:
Touchscreen does work in the login screen perfectly. After you log in the touchscreen works for few seconds and after that stops working.

I use the touchscreen for application development testing. So hope this get solved. Anyone a quick fix for this?

[Herman Willems (hermanwillems)]

I also found a trick how to make it work again, you close the lit of my XPS15 laptop and open is again. Then it works again.

(Maybe helps some people who really need this to work ASAP for development)

Maybe it has something to do with the Gnome Session? As the touchscreen works in the login screen, then after login it stops working after "one" touch. Then closing the lit and the touchscreen works fine again.

I have an XPS-15-9530 Dell laptop.

[MankyGitt (dnadruff)]

@Herman Willems: Thanks for this trick. I can confirm that this trick also works for me on my 2015 Dell XPS15.9530

However: If I use the physical keyboard, the touch screen is disabled until I repeat the trick of closing the lid.

[Jerome Droniou (jdroniou)]

I have a very similar problem with the touchscreen not working (most of the time) on my DELL Latitude 7400 2-in-1, except that when it does not work, it does not even work on the login screen. Closing the lid or restarting does not help. Then, from time to time, the screen works again...

My touchpad is also recognised as both mouse and touchpad, but that does not prevent it from working properly. The problem is solely with the touchscreen, which is simply unreactive (most of the time) although it does properly appear in xinput:

[Sam Hudson (slippykitty)]

I am also having a very similar problem on my Dell Inspiron 5390 runnin ubuntu 20.04.1 LTS. The output from running xinput reads:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DELL091F:00 27C6:01F0 Mouse id=10 [slave pointer (2)]
⎜ ↳ DELL091F:00 27C6:01F0 Touchpad id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]

    ↳ Power Button id=7 [slave keyboard (3)]
    ↳ Sleep Button id=8 [slave keyboard (3)]
    ↳ Integrated_Webcam_HD: Integrate id=9 [slave keyboard (3)]

    ↳ Intel HID 5 button array id=13 [slave keyboard (3)]
    ↳ Dell WMI hotkeys id=14 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)]

After booting the laptop up I have no problems with the touchpad, I also noticed that after a cold boot if i run "xinput test 11" and "xinput test 10" only device 11 (touchpad) registers any inputs. However, once i suspend the laptop and then wake it the touchpad loses lots of functions (basically functions like a mouse no gestures work) and right click also becomes middle click. If i again run both of the xinput tests again the only device that registers inputs is now device ID 10 (the one labelled mouse)

I have the same problem with Kubuntu 04/20.1 LTS after upgrading from Kubuntu 04/18.x LTS. I'm using xserver-xorg-input-libinput as a driver. I've tried other drivers but without success. No change after installing the xserver-xorg-input-evdev driver. And after installing the xserver-xorg-input-synaptics driver, the touchpad worked again, but the keyboard didn't. I don't understand why this bug is classified as low importance. I only use my laptop as a mobile device and cannot use it without a touchpad. And now you have to carry a mouse with you everywhere.

[artemw (artemw)]

A workaround that works for me is to disable mouse using `xinput --disable 11` and enable touchpad `xinput --enable 10`. Use `xinput --list` to find out the id of the devices.

Hi Guys,

I am facing the same issue. My laptop is T440p. The touchpad does not work after the login screen.

Hello,
I have the same issue on lenovo yoga 7i. Touchscreen, sound and fingerprint don't work, I ended up going back to windows. I feel like I dropped the soap in prison, please help me get out the jail :(.

[altadeos (altadeos)]

Hello,
I have the same problem with a M3800 Dell laptop.
Can you try to remove fwupd like in this topic ?

My open bug is https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-libinput/+bug/1886912

Hope it can help developers to solve this bug.
