# 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
