[SOLVED] Terminal keeps printing ^@ when installing Archlinux

Hello,

I'm trying to install Archlinux on my new laptop. After booting from a usb flash drive, the terminal keeps printing ^@ in the output whenever I execute a command. The command itself is running normally.

It makes reading the terminal output difficult, which I can overcome. But I'm stuck at changing user's password as the command passwd says no password has been supplied no matter what I type.

Here are the things I have already tried, none of them works:
  - Switching installation image from archlinux-2023.08.01-x86_64.iso to archlinux-2023.06.01-x86_64.iso
  - Enable/disable fingerprint reader in bios.

Looks as if a key is stuck or broken on the keyboard, but I couldn't find out which one. I would be very grateful if any could help me locate the problem.

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

^@ is the null character and unfortunately a virtually unsearcheable token hmm
Does it happen when you boot w/ "acpi=off"?

What exactly is your new laptops vendor/model?

Thanks for the reply!
I'm using honor magicbook 14 2023. https://www.hihonor.com/global/laptops/ … k-14-2023/

Does it happen when you boot w/ "acpi=off"

Unfortunately the system won't boot with acpi=off, grub stuck at "Loading initial ramdisk..."

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

sudo libinput list-devices | curl -F 'f:1=<-' ix.io

Can you disable
- webcam
- wifi

keeps printing ^@ in the output whenever I execute a command

Can you be more specific? Does it print an extra ^@ whenever you hit enter, spawn a process* or is it just stray, random input?

*

for ((i=0;i<10;++i)); do sleep 1; done

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

sudo libinput list-devices | curl -F 'f:1=<-' ix.io

returns http://ix.io/4EAI

I've disabled as many options as I can in bios, including:
- Secure boot
- TPM
- Virtualization Technology
- HDD Device
- PXE Device
- Camera
- Audio
- WLAN
- Fingerprint
- OS Auto Recovery
But none can stop the ^@ character.

The extra ^@ starts printing halfway in the splash screen.  I think the corresponding key press event never stops. It's just that bash do not show this character when I'm typing commands. But as soon as there is a command running, ^@ is mixed in its output, like this:

^@^@
Arch Linux 6.4.7-arch1-1 (tty1)

archiso login: root (automatic login)

^@^@^@^@^@^@To install Arch Linux follow the installation guide:
https://wiki.archlinux.org/title/Installation_guide

For Wi-Fi, authenticate to the wireless network using the iwctl utility.
For mobile broadband (WWAN) modems, connect with the mmcli utility.
Ethernet, WLAN and WWAN interfaces using DHCP should work automatically.

After connecting to the internet, the installation guide can be accessed
via the convenience script Installation_guide.

If the input is unmotivated

libinput debug-events

might reveal the device causing it.

Also

lsmod

, there might be a wmi module misaliased.
https://bbs.archlinux.org/viewtopic.php … 3#p1922573

Also input_polldev has previously caused this.

I failed to find any suspicious key press event except for the last ctrl+c I pressed. Perhaps it is because whichever key causing this issue, is already in the "pressed" state?

Sorry I couldn't find a way to blacklist input_polldev on archiso. All the changes are lost after reboot.

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

I think the module has been removed from the kernel anyway (and it's not loaded)
You could however try to add "module_blacklist=huawei_wmi,wmi_bmof" to the kernel parameters, https://wiki.archlinux.org/title/Kernel … acklisting

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

module_blacklist=huawei_wmi,wmi_bmof did not work hmm

However, I've finally located the device generating the key press event.

root@archiso ~ # evtest --grab /dev/input/event13
Input driver version is 1.0.1
Input device ID: bus 0x18 vendor 0x27c6 product 0x1e0 version 0x100

I think the next step is to find the driver and unload it from kernel?

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

That's part of the touchpad?
Try to blacklist i2c_hid_acpi - otherwise "cat /proc/bus/input/devices"

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

Yes. I've found 3 devices linked to the touchpad:

-event7   DEVICE_ADDED            GXTP7863:00 27C6:01E0 Mouse       seat0 default group5  cap:p left scroll-nat scroll-button
-event8   DEVICE_ADDED            GXTP7863:00 27C6:01E0 Touchpad    seat0 default group5  cap:pg  size 119x70mm tap(dl off) left scroll-nat scroll-2fg-edge click-buttonareas-clickfinger dwt-on dwtp-on
-event9   DEVICE_ADDED            GXTP7863:00 27C6:01E0 UNKNOWN     seat0 default group5  cap:k

Only the last one generates the key press event.

Try to blacklist i2c_hid_acpi

That works! However it also disables the normal touchpad (event7 and event8). Is there a way to precisely remove event9 only? smile

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

Running "evtest --grab /dev/input/event13" should™ suck the events and you can use a second VT free of that input.
But afaiu the primary task is to get through the installation process (which won't require a touchpad) and eg. on X11 you can just "xinput --disable" the device

Does the notebook have an ambient light detector?

I think so.

As we now have a good enough solution to complete the installation process, I'll mark this issue as solved.
@seth Thank you very much for the help!

Re: [SOLVED] Terminal keeps printing ^@ when installing Archlinux

Hi everyone!
I am very new for linux, I didn't find a way to save the config with blacklisted module on my usb drive, that has archlinux.iso.
So, there is simplier solution:
1. Shutdown
2. Start and wait until grub menu appears (the screen, where
"Arch Linux install medium (x86_64, UEFI)
"Arch Linux install medium (x86_64, UEFI) with speech
Memtest86+
etc
are displayed)
3. Select the first one and do NOT press Enter
4. Press E
5. Go to the very right corner
6. Print linux /boot/vmlinuz-linux ... modprobe.blacklist=i2c_hid_acpi
7. Press Enter
That's all. No more ^@ You can install archlinux and then write config.
If you do not write config, this problem will back, so you will need to do these manipulations again.

Thx, guys, for this topic, it helped to much!

Sorry for my English smile
