Touchpad recognised as PS/2 mouse on Asus N750JK

Hi,

I'm trying to get the touchpad working on an Asus N750JK. By default it is shown as PS/2 Logitech Wheel Mouse. I've tried installing psmouse-elantech and psmouse-alps-driver but with no success (at most I can get it to show it as Elantech PS/2 Mouse).

When running xinput list i get:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ PS/2 Logitech Wheel Mouse               	id=13	[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)]
    ↳ USB2.0 HD UVC WebCam                    	id=10	[slave  keyboard (3)]
    ↳ Asus WMI hotkeys                        	id=11	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=12	[slave  keyboard (3)]

Hi paulherman the problem affects also Asus N550JK (or JV) laptop, it was reported here and here but no one seems to consider it.

I would be glad to have suggestion on how to fix this or how bump this to upstream.

Yes, there are a lot of Asus laptop with this problem, I haven't found any solution, bug reports seem to be methodically ignored.

The bug seems to be fixed in kernel kernel-3.16.3:

Can you try it?

With the Asus N550JK the bug is still present with kernel 3.17.2-1.

Re: Touchpad recognised as PS/2 mouse on Asus N750JK

There is new work in Foaltech drivers.
Code for it is hosted in github: https://github.com/mgottschlag/linux/tree/focaltech3
More information about it you can found in Ubuntu Launchpad: https://bugs.launchpad.net/ubuntu/+sour … ug/1372609

I tried to compile modules for Focaltech for x200ma, but all patches are not working properly (in my builds). So maybe someone can be able to try it out?

Re: Touchpad recognised as PS/2 mouse on Asus N750JK

ha!

I managed to prepare patchset of touchpad and bluetooth for Kernel3.17.6.
I have compiled kernel for x200ma (Linux-ck-atom) and everything is working great!
sbaragnaus if you wish you can download my compiled kernel and check on your PC.
here is the link:
https://mega.co.nz/#!vJYzhBzQ!WrjPhGuZI … psNrHr2tdM
Inside zip you can find kernel + headers and xorg configs for backlight + touchpad.

If you wish I can attach patches tomorrow.

Re: Touchpad recognised as PS/2 mouse on Asus N750JK

I don't know what hardware you have in your PC. If it is Focaltech you can use this patch (it is for Linux 3.18.1) :
http://pastebin.com/Nw1L5pXN

and in config add line:
CONFIG_MOUSE_PS2_FOCALTECH=y

Also for good recognization you can add to your xorg config this:
