Touchpad wont work even with script #126
Description
Earlier, I reinstalled my OS to an external thumb drive due to the SSD firmware issue. However, I have since been unable to get the touchpad working. My touchpad, even when disabled, seems to be causing random things to happen with moving the cursor around randomly while typing if my hands get anywhere near it (which is making this difficult to type). The cursor can be clicked, unless it is disabled, but it cannot move. This sounds similar to the previous issue, but sadly the enable-amtel.sh script did not fix this for me. I tried manually running mxt-app on each of the i2c buses, which changed from 7 to 0 between boots, but it simply does nothing. Another note: I moved from v4.4-7 to v4.4-6 right before the SSD firmware gave out, but the touchpad worked fine and this didn't happen before. Perhaps it may have something to do with that fact that I am booting externally?
Here are the dmesg lines that appear to be the problem (but maybe not):
[ 66.778721] i2c /dev entries driver

I've updated the
enable-atmel.shscript with a new version that reconfigures the devices. This should only be needed to run once. See dca5e3d.Original suggestion from https://lkml.org/lkml/2016/4/8/536.

Thanks, I'll give it a try later today and see if it works.

i just ran the
enable-atmel.sh. it seems that after waking up from the suspend the system cursor works for a few second and it stopped working. chromium touch event works surprisingly. resetting usingmxt-appdoes not make the system cursor even work anymore.myf commentedon Apr 14, 2016
this took another interesting turn: as i tried to use multiple finger gesture on my chromium page, it seems that system cursor starts to work again. after waking up from subsequent suspend the system cursor keeps working well. interesting.
im just documenting this here as empirical study.

haha the pixel touchpad is one interesting mysterious beast :) it's been working fine for me since I applied to config change. Thanks for the report.

So I've finally had some time to update my Pixel. I'm using the new
enable-atmel.shand it's in its appropriate place in/usr/local/bin/enable-atmel.sh. It's been working good so far. I had one hiccup like @myf though. I had Chromium and a pdf open in zathura at the same time. I closed my Pixel to test sleep/wake if the problem had gone away. It seemed Chromium stole touchscreen focus since the touchscreen wouldn't work in i3 or zathura. It seemed to happen on wake since the pinch to zoom either got activated by itself or I accidentally had two fingers on the screen and didn't notice. I don't know if that has anything to do with it though. I don't recall Chromium having pinch to zoom, so that's nice to have that. My touchscreen feels a bit more useful now. I rebooted and can't seem to replicate the error.I played around a bit with Firefox with the Grab and Drag extension again since that seemed to be an issue before. I haven't had any problems yet. For now everything seems to be working great. I'll report back if the problem shows up again. I'm cautiously optimistic that everything touchscreen related has been worked out.
All I want now is to have the Grab and Drag extension to work as smooth as Chromium's native touchscreen support. :P

I updated my kernel to linux-samus4 4.8.7, and my touchpad and touchscreen stopped working. I downloaded and ran the enable-atmel.sh script (after installing mxt-app) and my touchscreen works, but my touchpad still doesn't work. Here's the output from
enable-atmel.sh:bendavis78 commentedon Nov 14, 2016
Update: my touchpad works now (randomly), but my touchscreen still doesn't work.

I managed to resurrect my touchpad/touchscreen. It quit working after a failed attempt to upgrade the kernel to linux-4.11.3.
What finally worked was using mxt-app to load a config I found in a ChromiumOS git repo:
git clone https://chromium.googlesource.com/chromiumos/overlays/board-overlays
git clone https://github.com/atmel-maxtouch/mxt-app
cd mxt-app/
sudo apt-get install build-essential autoconf libtool
./autogen.sh && make
cd ..
sudo modprobe i2c-dev
sudo ./mxt-app/mxt-app -d i2c-dev:0-004a --save atmel-maxtouch-pad.BAD.cfg
sudo ./mxt-app/mxt-app -d i2c-dev:1-004b --save atmel-maxtouch-screen.BAD.cfg
sudo ./mxt-app/mxt-app -d i2c-dev:0-004a --load board-overlays/overlay-samus/chromeos-base/chromeos-touch-config-samus/files/337t.raw
sudo ./mxt-app/mxt-app -d i2c-dev:1-004b --load board-overlays/overlay-samus/chromeos-base/chromeos-touch-config-samus/files/2954t2.raw
Be sure to verify the device addresses, and diff the bad config with the config you plan to load. There were only a few differences in my case.
