Laptop keyboard not working after boot

dkkf16 · September 3, 2023, 4:36pm

Hi all,
I am a new forum user, but quite an old Fedora fellow. I bought an ASUS Expertbook B1 without OS and I was trying to set up a fresh Fedora 38 install through USB boot device. The installation was smooth and the laptop works fine with BIOS settings and boot options, but, after booting the system, the laptop keyboard becomes totally unresponsive, with the CapsLock led lit.

Searching on Google, I found that several people before me experienced internal keyboard problems on new laptops under different Linux distros (Fedora/Ubuntu/Mint etc.) and most of them traced the problem up to the i8042 kernel module. So, I tested the following kernel parameter set:

BOOT_IMAGE=(hd0,gpt2)/vmlinuz-6.2.9-300.fc38.x86_64 root=UUID=c0b68eb2-fdea-4922-aef5-ce4ff77f5e36 ro rootflags=subvol=root quiet i8042.debug=1

I then plugged in an external keyboard and issued a dmesg | grep i8042, obtaining:

[    0.000000] Command line: BOOT_IMAGE=(hd0,gpt2)/vmlinuz-6.2.9-300.fc38.x86_64 root=UUID=c0b68eb2-fdea-4922-aef5-ce4ff77f5e36 ro rootflags=subvol=root quiet i8042.debug=1

[    1.780891] i8042: [419] Interrupt 1, without any data

Now, the “PNP: PS2” stuff can be solved by further adding a i8042.nopnp=1 kernel argument, but the keyboard remains unresponsive after system boot. Checking the journalctl boot error report (journalctl -b -p err) I got the following:

Could anyone help me understand why the laptop keyboard stops responding after boot (in spite of working perfectly in BIOS and GRUB) and hopefully solve the problem?

Thanks in advance!

I don’t know anything about the i8042 driver. But it appears to have many parameters that you could experiment with (same as you did with debug and nopnp).

$ modinfo i8042

file:           drivers/input/serio/i8042
description:    i8042 keyboard and mouse controller driver

parm:           unmask_kbd_data:Unconditional enable (may reveal sensitive data) of normally sanitize-filtered kbd data traffic debug log [pre-condition: i8042.debug=1 enabled] (bool)

Both kbdreset and unlock look interesting to me. (“bool” is short for boolean and means that the setting can be turned on or off by assigning 1 or 0 respectively.)

The keyboard worked when you used the live usb?

Suggest you record the kernel version that the live usb uses.
Can tou downgrade to that kernel? Does that make the keyboard work?

Also you can explore the state of the system when in the live usb and look for differences.

Hi,
thanks to @glb and @barryascott for looking in my post. It looks like the issue was indeed caused by the kernel version, but in the opposite direction (i.e., needed update, not downgrade). Yesterday, I was working with kernel 6.2.9-300.fc38.x86_64 and limited internet connection. Today (with a better internet), I allowed the system to upgrade to kernel version 6.4.13-200.fc38.x86_64, after which, the keyboard is typing happily

Below is what I did (after system update):

edited /etc/default/grub to have the default linux line running as

GRUB_CMDLINE_LINUX_DEFAULT="quiet i8042.debug=1 i8042.noaux=1"

executed sudo grub2-mkconfig -o /boot/grub2/grub.cfg
rebooted and… everything works!

I would then narrow the solution down to using the noaux=1 flag (because there is no PS2 mouse) and upgrading kernel. There is no need to disable the whole PNP.
