[SOLVED] systemd-module-load failed insert module no such file or dire

In order to fix some problem of my screen, I installed [this kernel module](https://github.com/carlicious/intel_backlight_fix).

I ran

make
sudo make install
sudo make dkms

This module can be added to the kernel successfully, and it's working well.

sudo modprobe intel_backlight_fix
lsmod | grep intel_backlight

I also want it to be automatically loaded at boot, so I add a new file 

/etc/modules-load.d/intel_backlight_fix.conf

and its content is

intel_backlight_fix

(from https://stackoverflow.com/questions/575 … matically)

However the module does not loaded after boot.
After some search I found that 

systemd-modules-load

is the services that autoloads the modules specified in that directory.

The result of 

sudo journalctl -eu systemd-modules-load

is

Sep 05 19:32:18 hostname systemd-modules-load[338]: Inserted module 'crypto_user'
Sep 05 19:32:18 hostname systemd-modules-load[338]: Failed to insert module 'intel_backlight_fix': No such file or directory
Sep 05 19:32:18 hostname systemd-modules-load[338]: Inserted module 'vboxdrv'
Sep 05 19:32:18 hostname systemd-modules-load[338]: Inserted module 'vboxnetadp'
Sep 05 19:32:18 hostname systemd-modules-load[338]: Inserted module 'vboxnetflt'
Sep 05 19:32:18 hostname systemd[1]: Finished Load Kernel Modules.

So how can I fix this and automatically load the module at boot?

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

You'll have to look at the configure script or the Makefile in the intel_backlight_fix source, to see where it's installing the module by default.  Most likely, systemd-module-load is not finding the necessary module file (intel_backlight_fix.ko, or whatever it's actually called) where all the other modules are found.

You will likely need to add a pacman hook that will recompile this module whenever a new kernel with headers gets installed.  I'd read up on DKMS before you continue.

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

I think the hook has been set up, since when I update the linux packages, dkms does build something.

The strange point is that both "vboxdrv" and "intel_backlight_fix" are dkms modules on my system, and their path is similar, but "systemd-modules-load" cannot find the latter.

The result of modinfo:

The dkms.conf seems similar except the DEST_MODULE_LOCATION. I've change it to another place, but dkms still installed them to "/lib/modules/5.19.8-arch1-1/updates/dkms/".

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

If you "systemctl restart systemd-modules-load" after the boot, does it succeed?
The module could fail for other reasons (eg. missing device node?) and system just reports nonsense as a generic error message.

If I restart systemd-modules-load.service after the boot, it insert the module successfully.

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

Check dmesg, there's probably a message from the module on the initial failure and looking at https://github.com/carlicious/intel_bac … ight_fix.c I'd assume it requires the presence of the backlight device.
It might help to load intel_backlight first, otherwise just create a service end enable if for the multi-user.target or use an udev rule that loads it when the backlight device shows up.

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

Since the recent KDE plasma update seems to fix the brightness problem, I no longer need this module, so I didn't try to create a systemd service that enables this kernel module, but I still curious about what's going wrong here.

Below is the result of "sudo dmesg | rg --context=5 intel_backlight_fix -i".

So should I somehow "sign" the module to make it usable? Or how can I check the required module of intel_backlight_fix? It seems that intel_backlight is not required (It even does not exists on my machine).

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

So should I somehow "sign" the module to make it usable?

No, that message says that you loaded some unvetted stuff and the kernel flags itself for that (for bug reports) - you can ignore that.

[    1.405292] intel_backlight_fix: loading out-of-tree module taints kernel.
[    1.405314] intel_backlight_fix: module verification failed: signature and/or required key missing - tainting kernel

Doesn't read like a failure to load the module at all; it then shows up around a kernel oops and no idea what the other two segments want to have matched.

Please post a complete system journal from a boot where the module loading initally failed ("sudo journalct -b | curl -F 'file=@-' 0x0.st" for the current one, "… -b -1 …" for the previous one etc.)

These are the current journal & previous journal:

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

http://0x0.st/oOLE.txt and http://0x0.st/oOLU.txt seem to be the same boot.
The pattern is always the same:

Sep 15 01:06:41 omelet-HP-pavilion kernel: intel_backlight_fix: loading out-of-tree module taints kernel.
…
Sep 15 01:06:41 omelet-HP-pavilion systemd-modules-load[338]: Failed to insert module 'intel_backlight_fix': No such file or directory
…
Sep 15 01:06:50 omelet-HP-pavilion systemd[1]: Created slice Slice /system/systemd-backlight.
Sep 15 01:06:50 omelet-HP-pavilion systemd[1]: Starting Load/Save Screen Backlight Brightness of backlight:intel_backlight...
Sep 15 01:06:50 omelet-HP-pavilion systemd[1]: Finished Load/Save Screen Backlight Brightness of backlight:intel_backlight.

You're trying to load the module before the systemd-backlight service (most likely) loads intel_backlight.
Therefore it'd also work afterwards.

The kernel oopsies are all unleated:

netdevice: wlo1: Incorrect netdev->dev_addr

From the context disabling https://wiki.archlinux.org/title/Networ … domization might help w/ that.

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

I'm not quite understand, does this mean that I cannot just add some dependency kernel modules in /etc/modules-load.d before "intel_backlight_fix" and fix the failure?

---

Also, I tried to disable MAC address randomization,

# /etc/NetworkManager/conf.d/wifi_rand_mac.conf
[device]
wifi.scan-rand-mac-address=no

but the error "netdevice: wlo1: Incorrect netdev->dev_addr" still occurs.

Maybe it's because I'm using this https://aur.archlinux.org/packages/rtl8852be-dkms-git.
The upstream repo has been archived, and I haven't tried the alternative driver https://github.com/lwfinger/rtw8852be (mentioned in https://github.com/HRex39/rtl8852be/blob/main/README.md )

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

Adding intel_backlight before intel_backlight_fix *might* work, otherwise I'd wait for the systemd-backlight service - in any event the service for intel_backlight kicks in fairly late and much after the attempt to load that intel_backlight_fix module (which is described as an ugly hack and will most likely make blind assumptions about the condition of the system - notably the backlight device present and intel_backlight being loaded)

Re: [SOLVED] systemd-module-load failed insert module no such file or dire

Thanks for giving so many detailed advises!

After some attempt I got this systemd unit. It automatically inserts the kernel module without failure.

# /etc/systemd/system/intel_backlight_fix.service
[Unit]
After=multi-user.target
Wants=systemd-backlight@backlight:intel_backlight.service

[Service]
ExecStart=/usr/bin/modprobe intel_backlight_fix
Type=simple

[Install]
WantedBy=multi-user.target

It's quite ugly, and as I mentioned, I no longer need this module, so I won't use this service.
I'll mark this question as solved.
