Touchpad stopped working 20.04

Question

I updated ubuntu 18.04 to 20.04. All worked fine for weeks until today. Touchpad on lenovo y580 stopped working just like that. I didn't install any new updates yesterday.

Xinput log:

Do you have errors in output of `dmesg | grep psmouse`? Does it work before you log in? Can you check if it works in `openbox` session? — int_ua, May 05 '20 at 18:17

doing `sudo rmmod psmouse` followed by `sudo modprobe psmouse` reloads a driver which sometimes helps to quickly get the mouse working again — Mladen B., Jan 10 '23 at 10:01

This is solution, that has worked for me:

sudo rmmod psmouse
sudo modprobe psmouse proto=imps

or

sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps

To make it permanent, edit:

sudo gedit /etc/modprobe.d/options

and add line:

options psmouse proto=imps

NOTE:

This fix will make the touchpad be recognized as a mouse instead, which might remove some features specific to touchpads such as disable while typing and scroll gestures.

Hope this helps.

`sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps` worked for me, but I can't seem to make it permanent after restart. – monkut Sep 05 '20 at 04:43

@monkut you can try this to add the command to be executed at startup: https://stackoverflow.com/a/9683384/12731060 – Ubuntovative is here Sep 07 '20 at 04:05
Thanks! I'm debating on doing a full re-install... Suspend seems to be failing as well. Something seems to have gotten messed up on my system. – monkut Sep 07 '20 at 04:17

Hmmm... Just re-installed 20.04 and have the same issue. I guess some update messed up the system. My hw works fine in my windows boot. – monkut Sep 08 '20 at 02:27

Looks like the problem may have been introduced in the kernel, `5.4.0-47-generic`. I selected the previous, `5.4.0-42-generic`, at grub boot load and the trackpad/trackpoint work fine now. – monkut Sep 08 '20 at 12:35

That was it @monkut! I think that deserves to be an answer, so that more can see this simple solution instead of the 2h of complex commands I had to live through – oma Sep 10 '20 at 20:17
This enabled tapping on the touchpad but disabled scrolling haha. Thanks though! – joshpetit Dec 17 '20 at 01:23
@joshpetit Yes I had already mentioned in my answer. – Ubuntovative is here Dec 17 '20 at 03:56

@GopalS wow, how did I miss the fact that you put **note** in bold. My fault haha! – joshpetit Dec 17 '20 at 11:33

To make this permanent, need to make that `options.conf`. _And_ need to do this afterwards: `sudo update-initramfs -u` – Shahbaz Mar 21 '23 at 23:13

I've been using 20.04 since august and just and at the end of August 2020, suddenly the touchpad/trackpoint stopped working on my Lenovo Thinkpad X1 extreme.

After struggling, getting it partially working, and eventually trying to re-install 20.04 3 or 4 times to fix the issue (initial install was fine), I found that the problem may have been introduced in the kernel 5.4.0-47-generic.

To work around this, I select the older kernel 5.4.0-42-generic at boot time by accessing the GRUB menu and going to Advanced Options.

Now I'm able to use the trackpad/trackpoint as before.

I still have a bit of a display issue with suspend, but at least I can work on my laptop again.

To configure the kernels and defaults to set, this Ask Ubuntu question is a good resource.

UPDATE

I raised a bug with ubuntu, and managed to resolve the issue in my case by changing the Config->Graphics Device value from Discrete Graphics to Hybrid Graphics. With Hybrid Graphics set in BIOS and running the lastest kernal/updates as of 2020-11-6 I'm able to use my trackpad/trackpoint.

This worked for me, way simpler and fast to test. None of the other commands worked for me, touchpad was not showing in `/proc/bus/input/devices` list when booting on new linux kernel. I'm also on ubuntu 20.04. Thanks monkut – oma Sep 11 '20 at 07:19
That also worked for me, my two cents here is to save the last kernel you have previously run, changing the file `/etc/default/grub` adding the entries: `GRUB_DEFAULT=saved` and `GRUB_SAVEDEFAULT=true`. After that, executing `sudo update-grub`. Source: https://askubuntu.com/questions/216398/set-older-kernel-as-default-grub-entry – Wellington Souza Nov 06 '20 at 08:17

Could you link the bug you reported to Ubuntu? I'm having a similar issue, but it's not solved with the steps here. – Herman van Rink Dec 05 '20 at 16:27
Hybrid graphics seemed to be the issue for me too on an Extreme Gen1, weird – Zach Bloomquist Jan 08 '21 at 15:57
Had the issue also with hybrid graphic. 5.8.0-36-generic kernel version fixed all issues for me. – wasserholz Feb 15 '21 at 12:19
@monkut, can you please please file a bug for the 5.4.0-42 -> 5.4.0-47 regression with the touchpad? I just changed my touchpad and with 5.4.0-144 it doesn't work. It looks like the Ubuntu team doesn't know about this regression. – Shahbaz Mar 21 '23 at 23:12

You can try reinstalling touchpad driver (synaptics in your case):

sudo apt purge xserver-xorg-input-synaptics
sudo apt autoremove
sudo apt update
sudo apt install xserver-xorg-input-synaptics

Restart and check.

I did that. After restart on the screen where you choose user i try to move cursor but he weirdly and fast jumps all over the screen and after few moments touchpad stop working. Also in xinput log now "PS/2 Synaptics TouchPad " is not visible. – scof93 May 04 '20 at 08:48
Issue this command to see if libinput is installed: `sudo apt list --installed | grep libinput`, if it's not there, you have to install the `xserver-xorg-input-libinput` package – Calico Cat May 04 '20 at 08:56
Among other things I got: libinput-bin/focal,now 1.15.5-1 amd64 [installed], libinput10/focal,now 1.15.5-1 amd64 [installed], xserver-xorg-input-libinput/focal,now 0.29.0-1 amd64 [installed,automatic] – scof93 May 04 '20 at 09:01
It seems you already have libinput, which is weird because I have had this issue before and installing `xserver-xorg-input-synaptics` fix the problem. It might also be that your touchpad is disabled (accidentally?). i suggest that you take a look at these wiki: [Touchpad not working after login](https://help.ubuntu.com/community/SynapticsTouchpad#Touchpad_not_working_after_login) and [DebuggingTouchpadDetection](https://wiki.ubuntu.com/DebuggingTouchpadDetection). The former provide some simple workarounds, while the latter gives more details and scenarios. – Calico Cat May 04 '20 at 11:25

Looks like reinstalling `xserver-xorg-input-libinput` works for me on Yoga 13 and Ubuntu 20.04. – ZhukovRA Aug 17 '20 at 21:24

This is dangerous if one has already removed `xserver-xorg-input-libinput` (https://askubuntu.com/a/783734/89062), as it will render the machine entirely unresponsive to all inputs. – MRule Oct 04 '21 at 08:24

I solved my touchpad problem on Ubuntu 20.04 with this:

Edit (create it if doesn't exist) the psmouse.conf file:
```
sudo gedit /etc/modprobe.d/psmouse.conf
```
Add the line:
```
options psmouse synaptics_intertouch=1
```

Then run:

sudo modprobe -r psmouse && sudo modprobe psmouse

Disabling and enabling the touchpad in Settings somehow solves the problem.

Not seeing any settings like that – Gk Mohammad Emon Apr 03 '22 at 18:27
Go to `Settings` >> `Mouse & Touchpad` >> Toggle `Touchpad` to disable or enable. `NOTE:` You might need a mouse to control the pointer when the touchpad is disabled. – Eric Gacoki Apr 04 '22 at 09:43
Didn't work for me :( – AlikElzin-kilaka May 20 '22 at 13:35
@AlikElzin-kilaka perhaps actually close the settings window and reopen, then it worked for me. – devunder Oct 08 '22 at 13:34

Here's an easy and quick way to do solve the problem:

Just press Alt+F2 and enter the command r. This will be restarting your environment for a while and then everything will work properly.

Well, all I did was to get to the “settings” and enabled the touchpad which surprisingly was disabled. I will check for the next few days if there is an issue and I will report here.

This touchpad issue happened on my ASUS N550JK and I think after I did “dist-upgrade” and my Linux distribution was upgraded.

I'm running into this situation every now and then on my Lenovo laptop. Trackpad suddenly stops working; sometimes the keyboard stops too. I can rescue things a bit with the virtual keyboard. ALt-F-R doesn't solve the problem. Reboots usually restore mouse/keyboard function. Recently, none of this worked, but plugging in the dongle of a Bluetooth mouse (I think) forced a bus rescan and restored mouse/keyboard function.

This just happened to me today with Ubuntu 20.04 5.4.0-100-generic kernel: just restarting the system with "shutdown -r now" fixed the issue.

Strange after that update on all 6 of my machines the update required a restart. So are you saying a second restart fixed it? – David Feb 18 '22 at 15:27

This was my problem showup use case: i was playing normally with ubuntu, then suddenly, for no apparent reason, the touchpad was like inexistent. The "sudo rmmod psmouse sudo modprobe psmouse proto=imps" suggested solution was transforming the touchpad in a mouse ie disablind the multitouch features so I didn't like it. Before trying more solutions I just restarted the system for double check and the problem was gone. My 2 cents – stefano perticoni Feb 21 '22 at 15:10

I was facing the issue on elementary OS 6.1 (based on Ubuntu 20.04), and the problem seemed to be related to ignore while typing option getting apparently stuck. Toggling this option from System Settings > Mouse & Touchpad > Device > Touchpad > Ignore While typing got it working back on.

Touchpad stopped working 20.04
