Hi everybody,

I've just get a new laptop: ASUS Zenbook ProUX501UW FY102T and after installing Gentoo the touchpad is not recognized. I've spent days googling and test a LOT of solutions but nothing worked.

What I've tried:

- test kernel from 4.3 to 4.9 (from official github this one)
- tried tons of parameters into kernel boot like noloop, nopnp, nomux, reset etc..
- installing synaptics, evdev, libinput
- Live CD ubuntu 14, 15 (16 freeze at the boot), latest fedora, arch linux: no one get a working touchpad
- compile the whole list of i2c drivers and load them as modules or in-built

It seems a lot of people got/is getting this problem, some patches have been pushed into the kernel to solve their problem but nothing worked for my case.

Before posting into kernel bugzilla and report this as a kernel bug, I would like your advices, maybe you will have some ideas that I did not try or something I made wrong. I cannot use my laptop without touchpad..

Here the important information:

Have-you try Gpm the console copy and paste mouse daemon? It have several drivers options you can try. If it work, you can use it as a repetitor for Xorg. It's the only thing I see you haven't try. No output tell the mark of your touchpad. Is it a Synaptics, an Elantec, do you know?

No I've no idea about of the mark of the touchpad. It seems that the touchpad and keyboard are on the same chip and controlled by the i8042 controller:

Code:

With a brand new hardware and using an antique kernel is definitely not a good approach.

Please try something recent and stable release from kernel.org. e.g. gentoo-sources 4.8.2

Usually touchpads are connnected wtih PS2 or usb protocol. And need some kernel settings and synaptics, and also the correct input devices in your make.conf for the X server

--

Well my opinion:

use experimental use flag on gentoo sources and enable skylake optimizations.
Use ~amd64 to get latest optimizations for your brand new hardware
the ~amd64 is far better choice because you have brand new hardware and needed anyway for latest webbrowser, nvidia binary drivers ...

Is nonsense as

* means everything, so use * or list up every license

when the box comes with windows, read out there how the touchpad is connected to the mainboard

I agree, I started by emerging the 4.8 and tried then a lot of kernels. The one I mentionned in myinfo is the last one.

I was still editing my post, please see above. I just had a look on your emerge info and overlooked the line that you tried every new kernel release.

So what does

Code:

Update:

I've used the latest Ubuntu LiveCD and it works!

Here the report:

Code:

H: Handlers=mouse0 event8
B: PROP=0
B: EV=17
B: KEY=30000 0 0 0 0
B: REL=103

Code:

ubuntu@ubuntu:~$ uname -r
4.4.0-31-generic


I've seen over various threads that designware was patched a lot to get touchpad working then not working etc..It seems this kernel owns a working one. But how to get the driver and be sure it is part of the 4.4.0.31 (or make a diff and applied a patch into my 4.8)

You should copy over the config. AFAIK there was somewhere the kernel config in use in another place too.

Check first if you get the kernel config with this
Code:
zcat /proc/config.gz

Okay, I get it working now on Gentoo. I've taken the config and the linux-source via the live cd (apt-get install linux-source) and use it as a new kernel into Gentoo.
I've the pad working. It remains a few things to fix but this one was the big one. It is a kernel regression.

Thanks for your help !!
