Hello all

The same happens to my laptop that I've bought a week ago (Asus FX503VM,
GTX1060).

I had already seen that the touchpad had issues with the default 4.15
kernel on Ubuntu 18.04 that I have installed. Therefore I have installed
Ukuu and managed to load later kernels.

Indeed running 4.17.11 had the touchpad working perfectly (no stuttering
and lag), but unfortunately with the freezing problem mentioned here,
present.

After some experimenting with the modules, I have realised that
unloading and loading the i2c_hid module fixes the freeze. After the
last post pointing at bugzilla for Fedora, I can verify that unloading
and loading the i2c_hid module fixes the problem which is also caused by
a five finger tap as stated there (for me it is sometimes caused even
during the two finger scroll).

I've now updated the kernel to 4.17.12 but the problem persists and no
fix seems to be incorporated. IMHO, the problem is at the i2c_hid
module. Let's hope that this will be fixed soon.
