Description Yill Din 2014-10-18 19:37:03 UTC 
Hi in this laptop the touchpad is being recognized wrongly as a "PS/2 Logitech Wheel Mouse", rather than as a touchpad.
In this configuration it only works to move the pointer or clicking, all the advanced features (multi-touch, pinch, zoom, scroll...) can't be properly configured.

This is the output of xinput:
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ PS/2 Logitech Wheel Mouse               	id=14	[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)]
    ↳ Video Bus                               	id=8	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=9	[slave  keyboard (3)]
    ↳ Asus WMI hotkeys                        	id=10	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=11	[slave  keyboard (3)]

Please let me know if you need specific output/logs or info.

I have exactly the same issue on an Asus UX303LN ultrabook. I am assuming they will be similar touchpads and require the same kernel fix... If not, I will file a separate report.

Of course I am also willing to assist anyone who could try to fix this.

Sorry, this is fixed for me in version 3.18.0! Yill, please check on your hardware.
Comment 4 Yill Din 2014-12-18 21:55:08 UTC 
The problem is still present in my ASUS with kernel 3.18.1 in Arch Linux.

Seems like that a lot of laptops are affected.
Comment 5 Marcos Souza 2016-11-17 03:35:08 UTC 
Can you please try a new kernel, and also provide a dmesg?

Thanks,
