ROG Flow Z13 Trackpad Fix

Overview

Fixes "Disable while typing" (DWT) + palm rejection on the ASUS ROG Flow Z13 folio keyboard touchpad. The detachable keyboard connects via USB, which causes the touchpad to be misclassified as "external," blocking DWT in KDE Plasma.

Files

fix-rog-z13-trackpad.sh — install script (run with sudo)
ROG_Flow_Z13_trackpad_fix_reference.txt — full documentation
rules/99-rog-z13-touchpad.rules — standalone copy of the udev rule

System Files Created

/etc/udev/rules.d/99-rog-z13-touchpad.rules — marks touchpad as internal
/etc/libinput/local-overrides.quirks — marks keyboard as internal (optional)

Root Cause

Systemd's 65-integration.rules sets ID_INPUT_TOUCHPAD_INTEGRATION=external because the USB device is flagged removable. Libinput refuses DWT for external touchpads. The built-in libinput quirk (50-system-asus.quirks) only marks the keyboard as internal, not the touchpad — libinput has no AttrTouchpadIntegration quirk attribute.

Fix

A udev rule at priority 99 overrides the property to internal after 65-integration.rules (priority 65) sets it to external.

Key Details

USB VID:PID = 0b05:1a30
Touchpad event device: event8 (identified by ID_INPUT_TOUCHPAD=1)
Touchpad input name: ASUSTeK Computer Inc. GZ302EA-Keyboard Touchpad
The keyboard and touchpad share the same LIBINPUT_DEVICE_GROUP, enabling DWT pairing
