Touchpad functions are missing after every cold-start


I didn’t even boot windows when I got the laptop :sweat_smile:.

I don’t remember having this issue when I had Manjaro installed, but i was on 5.14 or 5.15 kernel

the latest Manjaro Gnome release works on 5.15.x

Windows are the things to look out of or am I wrong? :stuck_out_tongue_winking_eye:

Since I’ve been busy renovating and refurbishing for the last three quarters of a year, I dug into my memories a bit.

Eventually I installed Fedora 35 and went kernel version by kernel version with dozens of cold starts, ending up with the following.

Fedora 35 with kernel version ‘5.16.20’ works great, the next version ‘5.17.2’ immediately kills the touchpad with the aforementioned phenomenon.

Only a “reboot” or a switch to “standby” brings the function back.

That’s a good find, at least we know its 100% a kernel issue now.

try to boot up with a fedora vanilla-kernel,
i try to perceive every possibility for a solution :face_with_diagonal_mouth:

[coffee@coffeepad ~]$ uname -a

without success.

[coffee@coffeepad ~]$ dmesg -t |grep elantech
psmouse serio1: elantech: synaptics_send_cmd query 0x01 failed.

directly went from “Suspend” after the “cold-start”.
