[SOLVED] Lenovo Ryzen Touchpad not recognized as a device.

slicesofpi · 2019-03-19 02:38:53

Hello all! I apologize if I leave any important details out, (against my own best interest), I'm new blah blah sure someone else has said it before. If there is any details or bits of information I can and should add (for the future particularly) or better practices it would be deeply appreciated to hear it.

Recently, I installed Arch on my new laptop (dual booting with windows) and things have overall been going pretty well using the wiki. I am using Gnome/gdm with xorg. I have libinput (xf86-input-libinput package) installed However, the TouchPad is not recognized at all as a device.

Here's the X: I want to get my touchpad recognized and working. It does not appear to be recognized at all, for example

[andrew@andrew ~]$ grep -e "Using input driver 'libinput'" /var/log/Xorg.0.log
[   262.129] (II) Using input driver 'libinput' for 'Power Button'
[   262.135] (II) Using input driver 'libinput' for 'Video Bus'
[   262.140] (II) Using input driver 'libinput' for 'Video Bus'
[   262.145] (II) Using input driver 'libinput' for 'Power Button'
[   262.151] (II) Using input driver 'libinput' for 'Integrated Camera: Integrated C'
[   262.161] (II) Using input driver 'libinput' for 'Ideapad extra buttons'
[   262.166] (II) Using input driver 'libinput' for 'AT Translated Set 2 keyboard'

and

Heres my Y:
Referencing the wiki on this problem and the referenced AskUbuntu source suggested adding the either one or more of the kernel paramters:

i8042.noloop i8042.nomux i8042.nopnp i8042.reset

.
After preforming

dmesg | grep PS/2

(I tried looking for psmouse, with no results) I got

 [    2.010575] i8042: PNP: PS/2 appears to have AUX port disabled, if 
this is incorrect please boot with i8042.nopnp

I tried using both the individual nopnp option adding it to my /etc/default/grub under GRUB_CMDLINE_LINUX_DEFAULT, then making the config and rebooting both with no avail to making the touchpad work or appear as a device. However, both times the message itself went away.

Any idea(s)? Much Appreciated.

Please use code, not quote, tags for pasted output: https://wiki.archlinux.org/index.php/Co … s_and_code

My bad, fixed.

I found this similar bugreport https://bugs.launchpad.net/ubuntu/+sour … ug/1787775
with this solution https://github.com/Syniurge/i2c-amd-mp2

Note: I do not have this laptop model and I don't know if this is the correct solution.

Also it seems that there is no package in aur for that. Read this https://wiki.archlinux.org/index.php/Dy … le_Support if you don't know what to do with the proposed solution.

Alright, I gave it a go according to the wiki and it's working! Thanks for the help, I'll mark it as resolved.
