Description Hosein 2021-12-18 08:14:34 UTC
After the latest stable updates, for both 5.10.84 and 5.10.85 gentoo-kernel-bin, my Acer VX15's touchpad is completely disabled.
I had to switch back to 5.10.78 to restore my touchpad.
However the recent kernels are fine if I go to bios setup and change my Touchpad driver to Basic instead of Advanced which requires I2C.
Mouse cursor doesn't appear in neither X nor Wayland so I'm positive it's kernel (and driver) related.

Reproducible: Always

Steps to Reproduce:
1. Type of Touchpad is on Advanced in BIOS setup
2. Boot on either kernels 5.10.84 or 5.10.85
3. Touchpad is not working
Actual Results:  
Touchpad not working

Expected Results:  
Touchpad working

Could you lsmod on both kernels, and diff the result?
Comment 2 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2021-12-18 18:33:30 UTC
(both = old/working and new/broken)

FWICS the following modules are no longer loaded by 85:

  hid_multitouch
  joydev
  vboxdrv
  vboxnetadp
  vboxnetflt

Could you try explicitly loading them one by one via modprobe and seeing if that makes the mouse appear again?  Also dmesg from 85 "advanced" mode could be helpful.

It didn't enable the touchpad unfortunately (although I didn't try importing vbox and friends since I already had rebuilt virtual box modules on 5.10.84 and nothing had happened.

Oh, and dmesg from 5.10.78 would also be useful for comparison.

This bug, somehow, got fixed on 5.15.11-gentoo-dist

Thanks!

Nope, oddly it just worked in the first boot, after that it still doesn't work.
