Comment 6 for bug 1798363

This has been an issue ever since I have used this laptop with any distribution of Linux. Up until 18.10 with touchpad would be non-functional. It would jump all over the screen and would basicaly be unusable with the laptop. Since 18.10. and kernel 4.17.4 the touchpad works as far as no longer jumping around the screen, but as soon as you touch the touchpad with all 5 fingers, it crashes and can no longer use the touchpad. Also, after about 10 minutes of use, the touchpad locks up and the only way to get it back is to either reboot the laptop or unload the kmods for the elan device and reload them and then you can use the touchpad for about 20 minutes again.
I created a cron job that does this every 5 minutes so that I can use my touchpad with out worry or I just use an external mouse.

The troublesome thing about this is that this laptop has been around for over a year, and with Windows, there are no issues, and with the UEFI BIOS, the mouse works with no issues. Just Linux.
