Trackpad sluggish response
#11
Received my PBP few days ago(thank you guys!). Installed last Manjaro. I'm also experiencing this issue. I have not applied keyboard update yet, but it seems not to fix the problem according to the comments above. Also waiting for some comments on this.
Some kind of temporary workaround is to slowdown acceleration but the issue is still annoying when selecting text, moving window borders, etc.
Basically I'm interested if this a hardware issue or this can be fixed some how on the program level.

Well, there is a workaround for the window resizing which is "Make the drag handles bigger."

https://ubuntu-mate.community/t/larger-w...ng/19981/2

Looking in the .xml file, the Green-Submarine theme has 3-pixel borders which are already 3x as easy to hit, and any of them may be edited if desired. High-Contrast Inverse has a whopping 6-7 px.

Also patched, but this issue have not gone.

The major issue is that the trackpad dimensions are reported incorrectly by the firmware. It reports a size of 30mm by 48mm only. This also causes another issue which is that palm rejection is ignored by libinput. It is possible to fix this by a file /etc/udev/hwdb.d/99-local.hwdb with following contents:

Code:
evdev:input:b0003v258Ap001E*
  EVDEV_ABS_00=::15
  EVDEV_ABS_01=::15
  EVDEV_ABS_35=::15
  EVDEV_ABS_36=::15

Reboot and you have very well behaved trackpad!

I recently applied this fix in firmware so you can also try flashing the latest version of jack humbert's keyboard updater fork to fix it instead of applying the evdev hdwd overrides.

Thanks for looking into this! It really makes a world of difference.

This didn't totally fix it for me, but it helped tremendously!  Thanks.

Thanks, rdschouw. I've already done this right after installing manjaro and it really reduces the impact, but the issue still exists. There is another issue. After playing videos, smth wired often happens and cursor moves unpredictably. Reboot or triggering event temporarily fixes that. I call this trackpad - coronapad =).
