Solved Issue with an unresponsive NLx0MU I2C TouchPad

Hey everyone,

I'm trying to get a FreeBSD workstation running on an 11th Gen Intel Clevo laptop (NLx0MU) with Xfce. Everything else is pretty smooth, but the touchpad is completely dead and I've hit a wall.

The kernel detects the hardware node (iichid0: <FTCS1000:00 2808:0101 HID I2C device> at addr 0x3-8 on iicbus14) and populates /dev/input/event0 through event9. However, iicbus14 shows <unknown card> at addr 0x38, and running libinput debug-events registers zero movement or click events when swiping the pad

Here is what I've done so far:

* Loaded ig4 and iichid in /boot/loader.conf.

* Tried loader tweaks like hw.iichid.sampling_rate="100"and hw.iichid.acpi_no_match="1".

* Added dev.ig4iic.0.pwrmgt=0 to sysctl.conf.

* Fixed devfs permissions so my user/wheel group has access to /dev/input/*.

Here are the exact command outputs from my terminal:



dmesg | grep -iE "ig4|iichid|iicbus|psm
output:

Has anyone gotten the FocalTech FTCS1000 I2C trackpad working under iichid on FreeBSD? Is there a specific ACPI/GPIO pin assignment or loader quirk required for this device?

Appreciate any help!

Update: Solved!

Installing x11-drivers/xf86-input-evdev was indeed the key to getting native I2C movement!

Initially, the touchpad only worked at the login screen (LightDM/SCDM) while remaining silent in the Xfce user session. The final piece of the puzzle was forcing Xorg to prioritize the evdev driver globally over libinput for touchpads, alongside verifying devfs permissions.

For anyone running into this FocalTech FTCS1000 touchpad issue on Clevo laptops, here is the complete fix:

1. Install the driver
Code: 
pkg install xf86-input-evdev

2. Force Xorg to use evdev for touchpads
Create /usr/local/etc/X11/xorg.conf.d/99-evdev-touchpad.conf:
Code: 
Section "InputClass"
    Identifier "Touchpad Evdev Catchall"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Driver "evdev"
EndSection

3. Ensure proper user access to input nodes
In /etc/devfs.rules:
Code: 
[system=10]
add path 'input/*' mode 0660 group wheel
add path 'input/event*' mode 0660 group wheel

And enable it in /etc/rc.conf:
Code: 
devfs_system_ruleset="system"

After a reboot, full native I2C multi-touch, tap-to-click, and two-finger scrolling work perfectly inside the Xfce session.

Thanks a lot for pointing me in the right direction T-Daemon.12345/">T-Daemon!
