"psmouse" module is built-in from 5.10.2 kernel. https://bugs.archlinux.org/task/69158

Fixed from kernel linux 5.10.13.arch1-2.

At some kernel version (I don't remember exactly, 4.12 most probably) the patch stopped working for me. So I spent a bit of time to debug it (via printk). And for me (HP Probook 4720s) the field priv->info.capabilities had bit 1 equal to zero (a-la value xxxxxxxx xxxxxxxx xxxxxx0x). So, masked with 0xD000FF it returned 0xD00071 instead of 0xD00073.

I don't know what these magic numbers mean, but what I did is changed the mask from 0xD000FF to 0xD000FD to skip checking this 1st bit and it works for me now.

wiselord, where did you get this numbers? For me it works without this changes.

wiselord commented on 2017-12-29 11:06 (UTC)

There is a piece of patch

  • if (!(priv->info.ext_cap_0c & 0x2000) &&
  • (priv->info.capabilities & 0xd000ff) != 0xd00073) {
  • printk(KERN_NOTICE "synaptics: led: failed capabilities check\n");
  • return false;
  • }

This one doesn't work for me (I get this kernel notice in dmesg), but when I replace the check with:

  • (priv->info.capabilities & 0xd000fd) != 0xd00071) {

,it works for me.

Sorry we should wait a little while arch update kernel from 4.14.8 to 4.14.9. Because 4.14.y that used for this module already 4.14.9 and have changes which make compilation failed.

Fuelen, thank you! SHA256SUMS updated, try to install now.
