Hello,

I've installed Gentoo on my Asus Zenbook UX305CA but I can't seem to get my touchpad to work at all. I've tried configuring both the synaptics and libinput drivers but it simply does not detect my touchpad (nothing in /proc/bus/input/devices). I also tried the Gentoo and Debian live usb but without any luck. However, the Ubuntu detects my touchpad and it works perfectly. As you can see, it sees my touchpad in /proc/bus/input/devices:
Code:

I: Bus=0018 Vendor=04f3 Product=0005 Version=0000
N: Name="Elan Touchpad"
P: Phys=
S: Sysfs=/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-4/i2c-ELAN1000:00/input/input12
U: Uniq=
H: Handlers=mouse0 event12
B: PROP=5
B: EV=b
B: KEY=e520 10000 0 0 0 0
B: ABS=663800013000003


What do I need to do to my Gentoo installation to make the touchpad work like it does so well on Ubuntu LiveUSB?

Thank you!

Neddih ...

does it show as being enabled (0=on,1=off)?

Code:
% synclient -l | grep TouchpadOff

You might try explicting enabling it:

Code:
% synclient TouchpadOff=0

I similarly don't have anything in /proc/bus/input/devices but the trackpad (APPLETOUCH) functions none the less (using xf86-input-synaptics).

How have you tried to "configure"? I'm tempted to think there is a software issue because there have been other similar reports, but you'll have to provide details otherwise we have nothing to go on.

best ... khay

On the Ubuntu live usb, when I do:
Code:

synclient -l | grep TouchpadOff


it returns:
Code:

TouchpadOff=2


However, when I try the same command on my Gentoo installation, it returns:
Code:

Couldn't find synaptics properties. No synaptics driver loaded?


As for the synaptics configuration, I did exactly the same thing as suggested in this article https://wiki.gentoo.org/wiki/Synaptics

I hope this clarifies my situation.

Any luck with this? I'm having a similar issue with an Asus Zenbook Pro touchpad. It worked in Ubuntu liveusb, and I've more or less copied the configs from there, but still have no touchpad.

Check your kernel config for these options:

Code:
CONFIG_MOUSE_ELAN_I2C


Code:
CONFIG_HID_MULTITOUCH


and maybe for:

Code:
CONFIG_MOUSE_ELAN_I2C_SMBUS
