This laptop labeling is strange. On the bottom of the laptop, it's listed as UX305C, while in dmesg it's showing UX305CA:

I just purchased the UX305CA laptop today, install Arch with latest kernel (4.4.3-1-ARCH available from Arch official repos), but ran into a few issues with the touchpad. Kernel 4.5rc6 is installing right now hopefully it will fix the issue. Works just fine with a normal usb mouse tho.

Haven't tried yet the HDMI connection yet, guess that will work fine. The brightness control buttons are not working at this moment either, but other than that the device works just great, can't really recommend it to anyone tho due to the malfunctioning touchpad which is pretty bad...

EDIT: The good news is that the network seems to working just fine. During the installation Arch recognized perfectly fine the USB --> Ethernet adapter and also the wifi. After the installation enabling the Network-Manager all worked fine.

EDIT2: Installing kernel 4.5rc6 solved the issue with the touchpad, but the brightness control on the keyboard is still not functional, the button which suppose to enable/disable the touchpad does seem to try to fulfill it's function, but now the pad is always on doesn't matter what state is the button set to. Overall it is working, small glitches, but I guess by time it will function properly.

EDIT3: After suspending the laptop for a long night it started to act a bit strange, touchpad wasn't working after it came back online and had to manually turn it off and back on again.

EDIT4: Ok, suspend stopped working properly... installing kernel4.5rc7 tonight...

EDIT 5: so 4.5rc7 seems to be the same thing, not really makes the suspend any more stable and/or reliable, but once it is back from suspend (usually need to press the power button once) can log in (keyboard always works), open terminal and restart udev seems to solve the freeze of the touchpad. Tomorrow will try the HDMI..

EDIT 6:

open terminal and restart udev seems to solve the freeze of the touchpad.

No it will not... what really happens is:

And what really fixes the issue with elan_i2c module (which is responsible for the touchpad's proper work in case of the UX305CA) is:
sudo modprobe -r elan_i2c && sleep 5 && sudo modprobe elan_i2c

EDIT 7: Ok so the HDMI connection freezes up the whole laptop immediately you plug it in so highly recommended to follow this: https://wiki.archlinux.org/index.php/intel_graphics#Skylake_Support Fixes the issue for me.

How is the UX305CA with linux nowadays?
