xinput을 통해 터치패드 감도를 변경하기 위해 .profile에 xinput set-prop 11 346 50 명령을 등록해뒀는데, 부팅 시마다 id가 변경되어서 계속 오류가 발생하는 것 같아. 동적으로 prop을 찾아 변경하는 스크립트를 작성해보자.

우선 다음은 xinput의 실행 결과야.

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ Lenovo Laser Wireless Mouse             	id=9	[slave  pointer  (2)]
⎜   ↳ Generic ThinkPad Dock USB Audio Consumer Control	id=16	[slave  pointer  (2)]

⎜   ↳ 2.4G RF Keyboard & Mouse Keyboard       	id=23	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]

    ↳ Generic ThinkPad Dock USB Audio Consumer Control	id=25	[slave  keyboard (3)]
    ↳ Logitech G304                           	id=11	[slave  keyboard (3)]
    ↳ Lenovo TrackPoint Keyboard II           	id=12	[slave  keyboard (3)]
    ↳ Lenovo TrackPoint Keyboard II           	id=14	[slave  keyboard (3)]
    ↳ 2.4G RF Keyboard & Mouse                	id=15	[slave  keyboard (3)]
    ↳ 2.4G RF Keyboard & Mouse Keyboard       	id=24	[slave  keyboard (3)]

여기서 Elan Touchpad의 옵션을 변경할거야.

다음은 xinput list-props 18의 결과야

여기서 libinput Scrolling Pixel Distance (346):	15 이 옵션을 찾아서 값을 변경할거야.

해당 값을 50으로 변경하면 돼. .profile 파일에 등록할 수 있도록 스크립트를 작성해줄래?
