libinput, which I believe, claims there is a kernel bug with the synaptics driver touchscreen in use. This is the recommended fix according to PostmarketOS. * https://wiki.postmarketos.org/wiki/Troubleshooting:touchscreen#sec_touchscreen:_kernel_bug I have not seen any issues from using this fix. The error: ``` synaptics: kernel bug: device has min == max on ABS_MT_WIDTH_MAJOR ``` According to the touchscreen documentation of the kernel, I don't think that it is an issue to remove this information from touch events.

Subject: [PATCH] s3320: Workaround libinput claiming kernel bug
|
|
|
|
I'm inclined to believe libinput here.
|
|
|
|
This solves:
|
|
|
|
```
|
|
display-manager[1880]: (II) event[0-9]+ - synaptics: is tagged by udev as: Keyboard Touchscreen
|
|
display-manager[1880]: (EE) event[0-9]+ - synaptics: kernel bug: device has min == max on ABS_MT_WIDTH_MAJOR
|
|
display-manager[1880]: (II) event[0-9]+ - synaptics: was rejected
|
|
```
