Keyboard not working on Asus Vivobook S 15 OLED K3502ZA

[Mirdarthos]

As far as I can tell, that laptop’s keyboard is still PS/2 and doesn’t work in (recent) kernels. Totally unsure 'bout that, so more than ready to be proved wrong.

Hy,

If you add the i8042.dumbkbd parameter to the GRUB_CMDLINE_LINUX the PS/2 keyboard will be shown in the output of the libinput list-devices (or xinput also), but sadly the keyboard still not working.

Here is my case:

[grxb@asus-s14x ~]$ cat /etc/default/grub | grep CMDLINE
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor resume=UUID=eeaa1257-889b-4419-9b95-ba09e5be0184 udev.log_priority=3 i8042.dumbkbd i8042.noaux i8042.noloop i8042.nomux i8042.nopnp i8042.notimeout i8042.reset=Y i8042.unlock i8042.kbdreset i8042.probe_defer"
GRUB_CMDLINE_LINUX=""

dmesg:

I have an Asus Vivobook S14 OLED K3402ZA, so I’m also interested the solution so much.

it’s better to open your own thread even if its the same problem or a similar problem.

Just tried this, downloaded the latest iso, installed using an onscreen keyboard. Still same problem.

Bios is at latest version.

[rbreahna]

it looks like this is a widespread issue with this line of laptops. If we can find a solution here this thread will be valuable to other people looking to use manjaro on this hardware

[anon51566685]

Try kernel 6.0-rc1 when available. It’s a shot in the dark though (I’m too lazy to figure out if there are any asus additions).

(Would be nice if mainline PKGBUILD for manjaro was available somewhere…sigh)

EDIT: Ok, it’s available now (PKGBUILD that is).

[Olli]

this model has even with ms-windows problems and need a specific driver for the normal use of the keyboard. good luck mates but this is a suspicious model.

[Shsrra]

just one more thing how can i apply the patch myself? listed there

[Olli]

as i understand this is jaus a preliminary, i can’t see any avaiable patch for now.

[anon51566685]

You need to compile kernel yourself:

• git clone desired kernel from manjaro gitlab
• download .patch file and put it in same directory
• edit PKGBUILD and add the patch
• build with makepkg

Thanks everyone the keyboard now works after patching and building the kernel!
