Fix touchpad disabled when resuming from suspend (maybe KDE specific)

[cies]

I found my touchpad not working after resume. I found some instructions here by user cscs, combined them with instructions from here and made them copy-pasteable:

sudo bash -c "cat > /usr/local/bin/restart-touchpad.sh" << EOL
#!/bin/bash
declare -x DISPLAY=":0.0"
declare -x XAUTHORITY="/home/$USER/.Xauthority"
sleep 1 # ensure the X server has started
xinput disable 'PNP0C50:00 06CB:CDB0 Touchpad'
xinput enable 'PNP0C50:00 06CB:CDB0 Touchpad'
EOL

sudo chmod +x /usr/local/bin/restart-touchpad.sh

sudo bash -c "cat > /lib/systemd/system-sleep/touchpad" << EOL
#!/bin/sh

case \$1 in
  post)
    /usr/local/bin/restart-touchpad.sh
  ;;
esac
EOL

sudo chmod +x /lib/systemd/system-sleep/touchpad

Can you specify your OS and kernel version because I haven't encountered this problem

Same problem here, Arch Linux with Plasma, Kernel 5.15 rc4.
The only temporary solution I found is to assign a function key to toggle the touchpad on.

Did you find any solution other than manually enabling the touchpad?
I find gnome 40 pretty good so far, but would like to go back to KDE

I've tried the latest unstable Plasma from arch's kde-unstable repo and the issue is still there.

No issues here. Never had the issue either.

I am on:

• 5.18.1-arch1-1
• Plasma 5.24.5

I have blacklisted elan_i2c:

❯ cat /etc/modprobe.d/blacklist.conf
blacklist elan_i2c

I am experiencing this issue

• Yoga Slim 7 15ITL05
• 5.18.9-arch1-1
• Plasma 5.25.2

have also blacklisted elan_i2c as above.

For anyone interested, I've found a "fix" which makes me think this whole thing is just a Plasma bug. You need to go into the keyboard shortcuts settings then deselect all of the keyboard shortcuts assigned to anything related to the touchpad. This fixed it for me.

Tested on Fedora Kinoite & KDE Spin.

Thank you so much. This solution solve my problem

Thank you for the solution. Issue still there. In my case deactivating disable touchpad shortcut helps.
