I am trying to get my touch pad to work but no luck so far. It appears there are other people many other people with this problem, but I haven't got anything to work yet. I have tried several distros other then Arch and I am getting the same problem on each except linux mint 30.3 "una" live boot with a pretty old kernel. My touch pad is detected and left and right click works, but I cannot move the cursor. This post is very similar but that solution isn't working for me: https://bbs.archlinux.org/viewtopic.php?id=228686/. I also found this which indicates someone has got it working semi-recently on my exact machine: https://linux-hardware.org/?probe=cbea798725.

Update:
I was reading this https://bbs.archlinux.org/viewtopic.php?id=244535
If I run rmmod hid_multitouch the touchpad begins to scroll the page and can't click. modprobe hid_multitouch reverts the touchpad back to previous behavior.
Offline
Been working on it some more. After looking at evtest I realized the problem is that it is registering touch up very frequently. I wrote a quick C program to fix this by just filtering out some data and pushing events to a virtual touchpad. That worked and touch pad moves/clicks, but the events just don't come in fast enough and to filter the events you kinda have to remove gesture support. I'm guessing there is some problem with the i2c_hid_acpi driver not following precision touch protocol. I'm going to give up on this because I don't have the skills to fix i2c_hid_acpi especially since there is no documentation on how PTP works.
Offline
I fixed this by changing to kernel 6.1. It appears there was a bug introduced into the i2c stack at some point. Bug is referenced here: https://bugzilla.kernel.org/show_bug.cgi?id=217701. I still can't get the touchpad working on latest kernel.
Offline
I bisected the Kernel and identified this commit at around kernel 6.9: https://github.com/torvalds/linux/commi … a51d20c2bc. I confirmed that removing the conditional added in this commit does restore touchpad support in latest kernel. I created this bug report https://bugzilla.kernel.org/show_bug.cgi?id=219799. I created this pull request: https://github.com/torvalds/linux/pull/1153. I emailed something similar, but I likely got the format wrong. If anyone could help out by creating a better solution then simply removing the old commit and submitting a proper PR anything is appreciated.

I would suggest replying to https://lore.kernel.org/all/20240321120 … intel.com/ if you have not already contacted the author the commit that introduced the issue.

Thank you for the reply, I will reach out to him. My "fix" causes very excessive interrupts so its not quite as simple as I hoped. I'm working on a workaround, but it would be great if this could get resolved properly.
Offline
If anyone else is having this problem in the future I fixed it by compiling and running this C program as a system d service. No need to modify kernel.

I'm on Mint and not Arch (for now...) but it worked for me, thanks for sharing! I've been searching everywhere for this for weeks now. I had the exact same symptoms and behavior as you on an ASUS UX564EI. If I didn't need secure boot for something on my windows partition I would have switched to arch just to try this already.

Thank you nunibye! I have been trying to get this working for a long time. It works on Arch, but also for Ubuntu. The link to your github for the code is broken, here is the updated with the updated code. https://github.com/eliahreeves/.dotfile … ad_monitor

Here is the idiots guide i had to make for myself using Brave Leo AI and nunibye's code:
To compile and run the `touchpad_monitor.sh` script as a system service, follow these steps:
1.Install `evtest` if you don't have it.
bash
sudo apt-get install evtest
2. **Save the script**: Create a file named `touchpad_monitor.sh` on your system in the file path of your choice, or use this one. You can use a text editor like `nano` or `vim` for this.
bash
sudo nano /etc/init.d/touchpad_monitor.sh
Copy this into the file, then save and exit:
#!/bin/bash
TOUCHPAD_NAME="ELAN1206"
find_touchpad_event() {
for device in /sys/class/input/event*/device/name; do
if [ -f "$device" ]; then
if grep -q "$TOUCHPAD_NAME" "$device"; then
event_path=$(dirname "$device")
event_num=$(basename "$(dirname "$event_path")" | sed 's/event//')
if [[ $(cat "$device") == *"Touchpad"* ]]; then
echo "/dev/input/event$event_num"
return 0
fi
fi

done
return 1
}
TOUCHPAD_EVENT=$(find_touchpad_event)
if [ -z "$TOUCHPAD_EVENT" ]; then
exit 1

CURRENT_TIME=$(date +%s)

IS_SLEEPING=true
fi
fi
done
3. **Make the script executable**: Change the permissions of the script to make it executable.
bash
sudo chmod +x /etc/init.d/touchpad_monitor.sh
4. **Create a systemd service file**: Create a new file in the `/etc/systemd/system` directory to define the service.
bash
sudo nano /etc/systemd/system/touchpad_monitor.service
Add the following contents to the file, then save and exit:
[Unit]
Description=Touchpad Monitor Service
After=network.target
[Service]
ExecStart=/etc/init.d/touchpad_monitor.sh
Restart=always
[Install]
WantedBy=multi-user.target
5. **Reload the systemd daemon**: Reload the systemd daemon to pick up the new service file.
bash
sudo systemctl daemon-reload
6. **Enable the service**: Enable the service to start automatically on boot.
bash
sudo systemctl enable touchpad_monitor.service
7. **Start the service**: Start the service manually.
bash
sudo systemctl start touchpad_monitor.service
8. **Verify the service**: Check the status of the service to ensure it's running.
bash
sudo systemctl status touchpad_monitor.service
You may need to restart the OS to ensure everything is working correctly.

Gald this is helping other people, I kinda thought I was the only one going through this. I do highly recommend switching to my C program. It has no dependency on evtest and uses a fraction of the resources. I only actually used the bash script for a couple hours since it is inefficient. https://github.com/eliahreeves/.dotfile … tor/main.c

If anyone needs I can write a tutorial, but its pretty much the same as what juanfibo wrote up, but you need to compile the program first and then use the executable in place of the bash script.
