Touchpad Not Working After 18.04LTS Clean Install

Is there a switch to enable or disable the touch pad? If so, use it. Is the touch pad enabled in BIOS?

Hey Andrew,

Thanks for your reply.

Well in Windows10 everything is working fine...

Add the boot options:

i8042.notimeout i8042.nomux

Source:
https://askubuntu.com/questions/533903/fujitsu-lifebook-ah544-touch-pad-not-working-in-ubuntu-14-04

Worked like a charm
:-)

Many thanks

Hey,
sorry to bother you again but...

...I just noticed that after sleep/hibernation the touchpad doesn't work...

μρ .

Hello again....

can anyone help me use my touchpad after sleep/hibernation ?

Many thanks
m.

Hey again,

With some research I've done here I found an answer to a similar question in this thread here:
Keyboard and touchpad doesn't work after stanby or hibernation (ubuntu 10.04):
(https://answers.launchpad.net/ubuntu/+source/acpi/+question/137940)

"...so in /etc/default/grub i wrote string:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash kbd.reset"
After that keyboard works after suspend and hibernation mode. I tested it about 10 times, so I think my problem is solved. :)"

The issue, maybe would be that, I have already edited my /etc/default/grub to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.notimeout i8042.nomux

How can I try to see if this solution helps?

ΤΝX
μ.

Just edit the line in the file and run:

sudo update-grub

Reboot to test

I added the extra line below the existing one...
...but it got worse.
After the reboot the touchpad wasn't working at all

For following the two different instructions at the same time you have to combine the parameters.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.notimeout i8042.nomux kbd.reset"

Hey Manfred,

Sorry didn't work. same issue still.

Which issue now - not working at all, or not working after hibernation and wakeup?

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Unfortunately  the issue is still persisting.
When returning from hibernation the touch pad doesn't work any more, only a usb mouse

What is now the value for GRUB_CMDLINE_LINUX_DEFAULT in your /etc/default/grub configuration file?

Hey again,

I read:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.notimeout i
8042.nomux kbd.reset"

Thanks again for your effort.

Is there a space inside "i 8042.nomux"? That should not be.

No there's not a space.
Sorry, was a typo

Ok.

If the touchpad is working after boot, but no more after hibernation and wake-up, then it seems to need some additional trigger at wake-up to get working again.

Some possibilities (found by a web search)

sudo modprobe -r psmouse
sudo modprobe psmouse

or

synclient TouchpadOff=1
synclient TouchpadOff=0

I suggest that you boot your system, but it into sleep mode and wake it up again.
If the touchpad is not working, try the first pair of commands. Does it bring the touchpad back into operation and/or show error messages?
Try the same with the second pair of commands.
And finally report the results.

Hey and many thanks for your effort,

I tried both sets into sleep mode and had following results:
Both sets didn't produce any error message BUT the fist set worked, in a
way, while the second set didn't work at all- the touchpad stayed frozen.
The fist set of commands seems more promising though as the touchpad from
frozen went alive after the second command (sudo modprobe psmouse).
The problem is that after a restart and a hibernation the same issue comes
back.

1. At least as a workaround you already know how to revive the touchpad after hibernation.

2. It is possible to automate this, such that the commands are always executed when the system wakes up from hibernation.
Examples are available in https://mariogalan.com/en/content/execute-script-after-suspend-ubuntu-1604 and https://www.addictivetips.com/ubuntu-linux-tips/run-scripts-and-commands-on-suspend-and-resume-on-linux/

hey,

I wrote, according the second follow-up (
https://www.addictivetips.com/ubuntu-linux-tips/run-scripts-and-commands-on-suspend-and-resume-on-linux/)
this

*#!bin/bash*

*# Restart Touchpad*

*if [ "${1}" == "pre" ]; then*
*# nothing goes here*

*elif [ "${1}" == "post" ]; then*
*sudo modprobe -r psmouse*
*sudo modprobe psmouse*
*fi*

I named it Restart Touchpad and saved in in */lib/systemd/system-sleep/*
Something must be fishy because it didn't work as planned. After
hibernation touchpad is still frozen.

With the fist link
https://mariogalan.com/en/content/execute-script-after-suspend-ubuntu-1604 I
couldn't figure it out.

What is the output of
ls -l /lib/systemd/system-sleep/

here's the output:

1. I recommend not to use special characters like space in a file name like this.

2. You have to give "execute" permission to that file (sudo chmod a+x filename).
If you re-check with "ls -l" afterwards, you should see -rwxr-xr-x like the other files.

I changed the name to restarttouchpad and run the command:
*sudo chmod a+x restarttouchpad*
the output now looks like the other entries but I still have a frozen
touchpad after returning from sleep mode.
Below the output:
kongking@UH572:~$ ls -l /lib/systemd/system-sleep/
total 12
-rwxr-xr-x 1 root root 92 Φεβ 22 15:51 hdparm

What happens if you wake up your computer and execute

/lib/systemd/system-sleep/restarttouchpad post

Does this bring the touchpad back to function?

Try removing "sudo" from the two lines. This should not be necessary, because the script already runs with admin privileges when started my systemd at wakeup.

Another possibility: Timing problems.
Add "sleep 5" bevor the first modprobe command.

"What happens if you wake up your computer and execute
/lib/systemd/system-sleep/restarttouchpad *post*"
What is the "post" at the end?

I executed in terminal like this, obviously wrong as i get back an error
message

*kongking@UH572:/lib/systemd/system-sleep$ sudo chmod +x restarttouchpad*
*[sudo] password for kongking: *
*kongking@UH572:/lib/systemd/system-sleep$ ./restarttouchpad*
*bash: ./restarttouchpad: bin/bash: bad interpreter: No such file or
directory*

my restarttouchpad file looks like this now, I removed sudo
*#!bin/bash*
*# restarttouchpad*

*if [ "${1}" == "pre" ]; then*
*# nothing goes here*

*elif [ "${1}" == "post" ]; then*
*modprobe -r psmouse*
*modprobe psmouse*
*fi*

I'll try your second option "*Add "sleep 5" bevor the first modprobe
command*."
and report back.

Also inserting sleep 5 didn't work.

*#!bin/bash*
*# restarttouchpad*

*if [ "${1}" == "pre" ]; then*
*# nothing goes here*

*elif [ "${1}" == "post" ]; then*
*sleep 5*
*modprobe -r psmouse*
*modprobe psmouse*

There seems to be a character missing in the first line. It should be
#!/bin/bash
with a slash after the exclamation mark.

Explanation for the "post" to be added when executing manually: The script is executed when going into hibernation, and at that time the parameter "pre" is used by the system, and at wake-up the script is executed with "post" as first parameter. Based on the parameter that is used when starting the script, either the first set of action (nothing) or the second (modprobe) is executed.

Hey
I added the slash in the file, but I'm confused regarding the  execution of the script....
I suppose I have to run it from terminal.
What is the exact syntax?

If everything is correct with the script, then it should be automatically be executed by certain system processes, whenever you wake up the computer from hibernating. No manual intervention required.

For testing whether the script works, you can manually start it:

sudo /lib/systemd/system-sleep/restarttouchpad post

If you get an error message, then something is (still) wrong.

Well as I received 2 errors, so something is, still, wrong...
Here's the output:
kongking@UH572:~$ sudo /lib/systemd/system-sleep/restarttouchpad post
[sudo] password for kongking:
/lib/systemd/system-sleep/restarttouchpad: line 7: syntax error near
unexpected token `elif'
/lib/systemd/system-sleep/restarttouchpad: line 7: `elif [ "${1}" == "post"
]; then'

BTW, I noticed just now doesn't work even the one-time hibernation that
used to work when adding the sleep 5.

What is now the contents of the script?

Please provide the output of

cat -n /lib/systemd/system-sleep/restarttouchpad

(unedited, without adding stars or something else!)

Here is the content of the script:

How did you create that file?
Maybe there are some strange unprintable characters.

I went into the directory and chose one of two  existing files. I edited it accordingly and saved it giving my admin password.
I didn't do it via terminal. Do you think that matters??

Let's try it slightly different:
Take /lib/systemd/system-sleep/hdparm as template.

Edit /lib/systemd/system-sleep/restarttouchpad

remove all contents and replace them with the following:
<start of text>
#!/bin/sh

case $1 in
  post)
    /bin/sleep 5
    /sbin/modprobe -r psmouse
    /sbin/modprobe psmouse
    ;;
esac
<end of text>

and then try again to manually start the script - any error messages?

Should I save it as restarttouchpad again?

The name should not matter. Just make sure that you have only one script for the touchpad in that directory.

And finally make sure that the file has got execute rights.

ok here is the new script:
<start of text>
#!/bin/sh

case $1 in
  post)
    /bin/sleep 5
    /sbin/modprobe -r psmouse
    /sbin/modprobe psmouse
    ;;
esac
<end of text>

I gave executive rights with the command:
kongking@UH572:/lib/systemd/system-sleep$ sudo chmod a+x restarttouchpad
and,
Here's the output of:
kongking@UH572:/lib/systemd/system-sleep$
/lib/systemd/system-sleep/restarttouchpad post
/lib/systemd/system-sleep/restarttouchpad: line 1: syntax error near
unexpected token `newline'
/lib/systemd/system-sleep/restarttouchpad: line 1: `<start of text>'

Hey again,

That's it.
It works now after any hibernation.
Many thanks for your help.

Thanks Manfred Hampl, that solved my question.

What I do not know is whether the "sleep 5" delay is really necessary. You could try reducing the number, or even deleting the line. If it still works, then that would be faster. But if you are satisfied with the current solution, then better leave as it is.

I think that I can live with a small time delay.
Once again many thanks for your time spent and help.
