Galliumos 3.1 Dell chromebook 13 ( LULU) touchpad issue

[wzdbsss]

Synaptics touchpad only works for a few minutes before it lags to the point where it freezes for about 30 seconds at a time.

I have do some research from the internet, like https://www.reddit.com/r/GalliumOS/comments/dhatej/dell_chromebook_13_lulu_touchpad_troubleshooting

Hardware:

Dell Chromebook 13 (7310)
CPU: broadwell
BIOS Firmware: tianocore UEFI(Full Firmware)

Distro

 Galliumos 3.1

I don't have freezing issues that you describe, but I find the tracking a bit flaky.

Here are some additional settings I use on my LULU (GalliumOS 3.1, firmware MrChromebox 02/04/2018):

xinput set-prop 'Synaptics TM3141-001' 'Synaptics Tap Action' 0 0 0 0 0 0 0
xinput set-prop 'Synaptics TM3141-001' 'Synaptics Soft Button Areas' 0 0 0 0 0 0 0 0

The solution in https://github.com/GalliumOS/galliumos-distro/issues/539 fixed the issue for my Dell 7310 running GalliumOS 3.1 using 40-touchpad-cmt.conf and 50-touchpad-cmt-lulu.conf from https://chromium.googlesource.com/chromiumos/platform/xorg-conf/+/refs/heads/release-R100-14526.B
