[url]https://www.spinics.net/lists/linux-input/msg51980.html[/url] Hi, from the 10_cat_sys_kernel_debug_hid_0018_04F3_3043_0007_events, your touchpad seems to work fine. You can verify with the “evtest” or “xev” to see if the events printed based on your touchpad move. So I think it could be the display driver issue. Please give me the information of the NVIDIA display in you G752VSK.
Is the issue occur with nouveau driver - I mean on newly installed fresh OS without nvidia driver? Please run and attach nvidia bug report to your existing post as soon as bug hit.
Hi sandipt, thank you very much for your reply.
I installed Ubuntu 17.04 while it was still in development. The initial situation was that both touchpad and USB mouse didn’t work at all: “It is very hard even to try Ubuntu 16.10 and 17.04 because of the missing mouse pointer. This problem must be related to a video driver because if after installing the Operating System one is capable to install Nvidia drivers - mouse problem is solved (touchpad remains completely dead). The missing USB mouse pointer problem doesn’t exist both while trying and installing Ubuntu 16.04.1!”
Currently everything is ok with the mouse pointer, both with and without Nvidia driver. My ELAN touchpad is completely dead both with and without Nvidia driver (laptop touchpad cursor doesn’t move at all, and both touchpad buttons doesn’t work too).
I tried out Fedora 26 and Fedora 25 i[/i] that use Wayland by default, Solus, Linux Mint, Manjaro… but ELAN touchpad remains completely dead (with Windows 10 touchpad works ok).

cases, it may hang trying to capture data generated dynamically
by the Linux kernel and/or the NVIDIA kernel module. While
the bug report log file will be incomplete if this happens, it
may still contain enough data to diagnose your problem.

I installed Ubuntu 17.04 on mu new G752VS yesterday and the ELAN Touchpad was completely non-functional. Today, out of no where and without any reasonable explanation, it started working after a resume from sleep (opened lid). Right now it’s fully functional, both buttons are working as well as tracking and multi-touch gestures (e.g. double-finger scrolling). All I did was install a few updates using the Software Updater today.
$ uname -a
Linux fzrog 4.10.0-26-generic #30-Ubuntu SMP Tue Jun 27 09:30:12 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 17.10 daily build (2017-07-10), kernel 4.10.0-19
Booted from Live USB, without USB mouse connected: ELAN touhpad doesn’t work at all, but al least touchpad cursor is visible all the time. I’ve tried to disable/enable the touchpad via system settings, but nothing changes.
After that, I suspended my Asus G752VS laptop via shutdown/suspend menu and then I disconnected the USB mouse. After waking up from suspend, my ELAN touhpad magically became fully functional - everything works fabulously.
Fedora Workstation 26, kernel 4.11.8
Booted from Live USB, without USB mouse connected: ELAN touhpad doesn’t work at all, but al least touchpad cursor is visible all the time. With the USB mouse connected, I’ve tried to disable/enable the touchpad via system settings, but nothing changes.
After that, I pressed the power button to suspend my Asus G752VS laptop and then I disconnected the USB mouse. After pressing once again the power button to wake up from suspend, my ELAN touhpad magically became fully functional - everything works fabulously.
As reported here
the trick should work also with Ubuntu 17.04 but that’s not my case. My current Ubuntu 17.04 was installed while it was still in development - so I will perform a new clean installation (without Windows) in the next few days.
