Automatically enable touchpad after suspend

bapman · 18 August 2020 13:12

Hello to the community!

I just installed Manjaro on my Lenovo Yoga Slim 7 laptop. It is quite new hardware so there are some troubles to be fixed on Linux.
One of them is that I loose the touchpad after each resume from suspend. I can re-enable it with the following command:

xinput --enable "PNP0C50:00 06CB:CDB0 Touchpad"

But my wife does not find it easy to get a terminal and launch this command only using the keyboard .
So I tried to automatize this after each suspend. I found two ways to do it:

Create a service launched after suspend

I created the file:

/etc/systemd/system/enabletouchpad.service

It is owned by root and executable. Here is the code inside:

[Unit]
Description=Enables touchpad again after resuming
After=suspend.target

[Service]
Type=oneshot
ExecStartPre=/bin/sleep 15s
ExecStart=xinput --enable “PNP0C50:00 06CB:CDB0 Touchpad”

[Install]
WantedBy=suspend.target

I am not sure about the sleep for 15 seconds but, anyway even after enabling the service:

sudo systemctl enable enabletouchpad.service

and rebooting, this does not work.

I also tried a “sudo -u ” but it also failed.

Script in systemd/system-sleep

I created this script owned by root and executable:

if [ "${1}" == "post" ]; then
xinput --enable "PNP0C50:00 06CB:CDB0 Touchpad"
fi

Still not working! Also tried with sudo -u…

Any idea?

After resuming, what is the output of systemctl status enabletouchpad.service?

Fabby · 18 August 2020 15:23

Instead of:

ExecStartPre=/bin/sleep 15s
ExecStart=xinput --enable “PNP0C50:00 06CB:CDB0 Touchpad”

do this instead:

 ExecStart=/usr/local/bin/EnableTouchPad.sh

sudo nano /usr/local/bin/EnableTouchPad.sh

copy-paste this:

#!/bin/bash
sleep 15
xinput --enable “PNP0C50:00 06CB:CDB0 Touchpad”

Hit Ctrl+X Enter to save

Execute:

chmod a+x /usr/local/bin/EnableTouchPad.sh

Finally, when coming back from suspend, try executing EnableTouchPad.sh all by itself and post any errors you get.

P.S. Congratulations BTW: you’ve just created your first bash script!

Thanks!

I tried to load the batch script instead but it did not work. From the status command, I get an interesting error:

EnableTouchPad.sh[2494]: Unable to connect to X server

mbb · 20 August 2020 22:57

It is being triggered before the X server. Try to trigger it after the resume or the graphical target.

Fabby · 21 August 2020 08:11

Can you add user=root to your [Service] section?
What does EnableTouchPad.sh do from a normal terminal? Any errors there? What is your sleep timer? 15 or less?

alluro2 · 21 August 2020 23:23

Got the same laptop a few days ago and have the same problem! (5.8 kernel, touchpad didn’t work OOB on lower).

Previously tried reloading psmouse module, but it had no effect - so thanks for the xinput hint, at least I can enable it manually without a restart when I need to. Looking forward to finding a solution to this issue.

Fabby · 22 August 2020 10:44

As bapman is not responding, feel free to share your effort in this. What’s the output of

EnableTouchPad.sh

from a normal window and does that restore the touchpad?

h_ramus · 22 August 2020 14:03

Hi. I too have the same model and encountered the same issues with the touchpad after resume. I’ve updated the BIOS to the latest DMCN32WW (release date 14/07/2020) but this didn’t resolve the touchpad issues.

Running the EnableTouchPad.sh on terminal after resuming from suspend activates the touchpad. However, it doesn’t work as systemd:

EnableTouchpad.sh[30605]: Unable to connect to X server

The command seems to run before X server graphical interface is running. I’ve tried other alternatives as well.

Edited the enabletouchpad.service to try to apply after the graphical interface is running. Doesn’t work. Same error message “Unable to connect to X server”. My file now includes:

[Unit]
Description=Enables touchpad again after resuming
After=basic.target suspend.target hibernate.target graphical.target graphical-session.target

[Service]
User=root
Type=oneshot
Environment=DISPLAY=:0
ExecStart=/usr/local/bin/EnableTouchpad.sh

[Install]
WantedBy=basic.target suspend.target hibernate.target graphical.target graphical-session.target

https://archived.forum.manjaro.org/t/solved-clevo-nh55-laptop-touchpad-hang-freezes-after-lid-close/104089/54 - didn’t work but I expected it to fail;
SYNA3602 touchpad not working at all - #24 by cscs - modprobe works (doesn’t need X server to run) for a couple of seconds and then it’s disabled. I also noticed that when re-enabling the touchpad manually my inverted scroll setting reverted to default;
compiled most recent kernel (5.8.2) but continued to have issues with the touchpad;
included the xinput --enable 'PNP0C50:00 06CB:CDB0 Touchpad' command in the ~/.xinitrc file but it also didn’t work.

I’ve managed the touchpad issue by assigning the F9 key to toggle the touchpad. Also, when the screen opens it doesn’t wake the OS. I need to press a key to wake up the device.

Other issues I’ve had with the slim 7:

suspend to ram is not advertised by the BIOS to the OS. ACPI S3 sleep is unavailable by default. I followed this post to enable sleep to RAM - https://www.reddit.com/r/linuxhardware/comments/i28nm5/ideapad_14are05_s3_sleep_fix/
brightness jumps to max when booting. Resolved this by setting a manual brightness in the ‘Power Management’ settings.

Overall, the laptop is running fine for the most part. Completely idle it drains around 2.5W - 3W on battery with very dim screen. I’m using tlp and auto-cpufreq which allows the cpu to ramp up under heavy load with turbo enabled a few seconds.

Let’s try a radical new approach and un/reload the module for that touchpad when coming back from sleep.

As I don’t have your hardware, what’s the output to:

grep /proc/modules "touch"

h_ramus · 22 August 2020 16:12

cat /proc/modules |grep touch
hid_multitouch 32768 0 - Live 0x0000000000000000
hid 143360 4 hid_generic,hid_multitouch,hid_sensor_hub,i2c_hid, Live 0x0000000000000000

I’ve tried with i2c_hid. The issue I had with this one was that it stopped working after a few seconds after resuming. My inverted scrolling also had reverted to default after manually enabling the touchpad.

Fabby · 22 August 2020 16:27

all out of bright ideas then…

h_ramus · 22 August 2020 16:52

Thanks for trying to help.

bapman · 22 August 2020 19:14

Yes, thank you! Very weird issue, it seems that systemd does not have the right to connect to the X server. If someone finds the solution, do not hesitate to post!

Fabby · 22 August 2020 19:20

the reason I wanted to take it to the module level, but as I don’t have your hardare, I need to find the module first…

cscs · 23 August 2020 02:00

/usr/bin/restart-touchpad.sh

#!/bin/bash
echo "Restarting Touchpad just in case"
declare -x DISPLAY=":0.0"
declare -x XAUTHORITY="/home/"$USER"/.Xauthority"
xinput disable 'PNP0C50:00 06CB:CDB0 Touchpad'
xinput enable 'PNP0C50:00 06CB:CDB0 Touchpad'

(you may need to make this file executable with sudo chmod +x /usr/bin/restart-touchpad.sh)

~/.config/systemd/user/restart-touchpad.service

[Unit]
Description=Restart Touchpad
After=basic.target suspend.target hibernate.target

[Service]
Type=oneshot
Environment=DISPLAY=:0
ExecStart=/usr/bin/restart-touchpad.sh

WantedBy=basic.target suspend.target hibernate.target

Then enable it:

systemctl enable restart-touchpad.service --user --now

Let me know how it goes. I think it should work

(EDIT - it seems some users may need to replace “$USER” in the above script with their actual username to reflect the actual path, ex: /home/cscs/.Xauthority)

h_ramus · 23 August 2020 03:07

Thanks for helping out! There still seems to be an issue with the systemd service.

Anyone else with the same error messages?

The command correctly restarts the touchpad after suspend. The issue seems to be on the systemd side.

cscs · 23 August 2020 03:17

I tested this and couldnt reproduce your issue …
Are you sure its copied correctly?
It must be a user service as shown above.
Maybe also check what is

echo "$DISPLAY"

h_ramus · 23 August 2020 03:23

echo “$DISPLAY”
:0

I had correctly copied the content of the files.

Anyone else?

Other Ideapad models seem to have issues with drivers but this one doesn’t seem to use elants - https://wiki.archlinux.org/index.php/Lenovo_IdeaPad_5_15are05#Touchpad`
