Touch screen stopped working (stylus works) on Thinkpad X1 Yoga 4gen about input-wacom HOT 7 OPEN

Checking to see if there's any update on this.

from input-wacom.

It's started to work again without any known change I made 🧑‍🦲 🔫

from input-wacom.

Reopend since it happen sporadically.

I can see this in dmesg:

hid-sensor-hub 001F:8087:0AC2.0005: timeout waiting for response from ISHTP device

from input-wacom.

I have this problem as well. And the cursor jumps around, causing constant havoc. There are many reports but I haven't seen a solution eg: #342 #262 #288

Originally, I thought it was because I was trying to use the lenovo or wacom active pen, but this also happens with the lenovo stylus which comes with the laptop (x1 yoga 5th gen).

modinfo wacom | grep version
version: v2.00
srcversion: CE2807BA4D6A356047D60C4
vermagic: 6.2.0-35-generic SMP preempt mod_unload modversions

Here is the output of libinput record for the stylus.

This issue has been around for a while, but I don't believe that its root cause is a driver issue (meaning that it can be very difficult to "fix" from the driver). There are too many instances of the bug appearing and disappearing without any obvious change to the affected system; let alone changes that I would expect to influence this.

I'll follow-up on some of the wilder possibilities of what could be going wrong, however.

I've made four branches that disable various parts of the driver and am interested in knowing if any of them have any effect on the jumping issue. You'll first need to clone my repository as follows:

$ git clone https://github.com/jigpu/input-wacom.git
$ cd input-wacom

Next you'll need to check out one of the four test branches:

• $ git checkout stylus-jump-A
• $ git checkout stylus-jump-B
• $ git checkout stylus-jump-C
• $ git checkout stylus-jump-D

Compile and install the code as per the wiki instructions and then reboot. Run cat /sys/module/wacom/version to verify what version of the driver is actually running. It should end with either g7e1c20e for A, g025759f for B, geaeb441 for C, or gd449720 for D. You can now use the modified driver for some time and see if it has any effect on the jumping behavior. If there doesn't seem to be any effect, try checking out the next branch and then repeat these steps again with it.
