Goodix Touchscreen not working after suspend

Question

I have a One Netbook 1s running Xubuntu. Everything works find except the touch screen does not work after suspend. I have seen several people with similar problems and it seems like there is a potential solution in this link:

https://github.com/jwrdegoede/linux-sunxi/commit/master

However, I do not understand the discussion there or what I am supposed to do with the material on github. I have tried a few solutions posted by people using Manjaro but they didn't work, perhaps because of the difference between Manjaro and Ubuntu...

This is a "Goodix" touchscreen. I am at the latest version of Ubuntu.

Update: You could try to do this. It worked for me. Note that you need to disable secure boot in bios to be able to run the script.

1. Install acpi_call package (sudo apt install acpi-call-dkms for Debian/Ubuntu, sudo pacman -S acpi_call-dkms for Arch). For Fedora you can install this module from tlp repo. https://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html

The kernel module provided by this package is mandatory to get the touch screen working after suspend (the folks at Onemix did not define any GPIO in their DSDT related to the goodix reset lines, but rather directly implemented a reset method in the DSDT, that we can call using the acpi_call kernel module). Remember to load the module via: "sudo modprobe acpi_call"

2. Create a new file /lib/systemd/system-sleep/goodixtouchscreen and put these contents :

    #!/bin/sh
    case $1 in
      pre)
        modprobe -r goodix
        exit 0
        ;;
      post)
        modprobe -r goodix || true
        sleep 1s
        echo '\_SB.PCI0.I2C2.TCSE.INTO 0' > /proc/acpi/call
        sleep 1s
        modprobe goodix
        exit 0
        ;;
    esac
