Video Intel awaking w wrong Brightness level
Hello, I've been able to set a specific brightness intensity at evry boot, by using an /etc/init.d/after.local script, but anytime my system awakes from suspended mode, the brightness resets to a very high intensity. from dmesg I see: [ 3.128757] i915 0000:00:02.0: [drm] Skipping intel_backlight registration [ 33.797331] ideapad_acpi VPC2004:00: Keyboard backlight control not available [28383.336476] video LNXVIDEO:00: Restoring backlight state How could I resolve this? Which file is used by Tumbleweed for an after suspend brightness adjustment? Thanks and regards, -- Marco Calistri Build: openSUSE Tumbleweed 20230213 Kernel: 6.1.10-1-default - XFCE: (4.18.1)

Showing this script may provide some hints. Also why do you need it? Normally the brightness is expected to be set using desktop environment configuration and preserved across reboot.

This should restore device brightness to whatever was set before suspend. Assuming your system is using ACPI backlight driver.
How could I resolve this?
You need to find out what and when changes the brightness. It could also be your desktop environment.

You can hook another script at restore from suspend or hibernation. See <https://lists.opensuse.org/archives/list/users@lists.opensuse.org/message/SMZGCEUR434DBEQ2MBPEVYTZYNC5UGQY/> for the idea. Notice that if your desktop restores brightness itself, it may be after that script runs. So perhaps add a delay. Another place that can change brightness is laptop-mode tools — I'm unsure of the name, though. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)

I tried to review your script but I cannot adapt it to my specific case. I also tried to set systemd backlight restore to 0 into kernel parameters without success. It will keep in this state which is not ideal and I hope that one day somebody will provide a valid solution because it is really an annoying fail! Linux should just let the stuff as it is, without touching nothing, but evidently it likes to mess it up! 😬 Regards, -- Marco Calistri Build: openSUSE Tumbleweed 20230217 Kernel: 6.1.12-1-default - XFCE: (4.18.1)

I would have to change your affirmation as follows: The script works as expected by writing the comments on the system log, but in the reality it does not adjust the brightness to the same value (*which is 1*) set at boot by the script I added into my /etc/init.d/after.local: #!/bin/sh #old script #echo -n 700 > /sys/class/backlight/intel_backlight/brightness #new script echo -n 1 > /sys/class/backlight/acpi_video0/brightness To be more clear: the setting of acpi_video0 brightness works at boot but it does not work after suspend, in fact in this case it goes at very high intensity so that I need to adjust it manually.

Well, just put there the value of brightness you want. If you want 700, put 700. Notice also that it is possible that something alters the brightness later, after the script runs.

ACPI video brightness driver should restore hardware state to this value on resume. It actually prints message that it's doing it.
but anytime my system awakes from suspended mode, the brightness resets to a very high intensity.
from dmesg I see:
[ 3.128757] i915 0000:00:02.0: [drm] Skipping intel_backlight registration [ 33.797331] ideapad_acpi VPC2004:00: Keyboard backlight control not available [28383.336476] video LNXVIDEO:00: Restoring backlight state
This should restore device brightness to whatever was set before suspend. Assuming your system is using ACPI backlight driver. I'm not sure about it... What I see from dmesg is: [ 28.188464] ideapad_acpi VPC2004:00: Keyboard backlight control not available
Keyboard backlight and screen brightness are two independent things.
How could I resolve this?
You need to find out what and when changes the brightness. It could also be your desktop environment.
Well, for the boot my issue is resolved but for the after suspend mode it is not and from what I see by Google it is a very common issue among Linux users.
Yes, but it also may be that first kernel restores brightness and then your desktop environment overrides it. Try booting into run level 3, set brightness, suspend and resume. Is brightness also reset in this case?
Which file is used by Tumbleweed for an after suspend brightness adjustment?
Thanks and regards,

Hmm ... I actually wonder why ACPI is used for brightness at all. Default should be to prefer native (intel_backlight in this case) unless overridden by system-specific quirks or manually. Can you provide full dmesg output?

Hello,
I've been able to set a specific brightness intensity at evry boot, by using an /etc/init.d/after.local script, but anytime my system awakes from suspended mode, the brightness resets to a very high intensity.
from dmesg I see:
[ 3.128757] i915 0000:00:02.0: [drm] Skipping intel_backlight registration [ 33.797331] ideapad_acpi VPC2004:00: Keyboard backlight control not available [28383.336476] video LNXVIDEO:00: Restoring backlight state
Hmm ... I actually wonder why ACPI is used for brightness at all. Default should be to prefer native (intel_backlight in this case) unless overridden by system-specific quirks or manually. Can you provide full dmesg output?
From what I read, this is a kernel issue started with 6.1 branch.
You read what?
Intel_backlight subfolder has simply disappeared from /sys/class/backlight:
I have no idea what you mean.
marco@linux-turion64:~> ls /sys/class/backlight/ acpi_video0
Attached dmesg---> https://drive.google.com/file/d/1bxutB4R1OzV1Qb5jWgEQEjJOxE-xn9q1/view?usp=s...
BIOS is from 2012 which means it probably predates Windows 8. In this case Linux kernel indeed will favor ACPI over native. Try booting with acpi_backlight=native kernel parameter.
Please notice that I removed then the "y-uuid/4ff65e75-c664-43d8-ab25-25d85336f6b8 mitigations=auto quiet i915.enable_dpcd_backlight=1", since that do not produce the expected result.

How could I resolve this? Which file is used by Tumbleweed for an after suspend brightness adjustment?
Thanks and regards,
Hello, It follows how I have resolved my issue. First of all, add the last parameter to /etc/default grub (in bold): GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/disk/by-uuid/4ff65e75-c664-43d8-ab25-25d85336f6b8 mitigations=auto quiet *acpi_backlight=native*" Then create the following file: */etc/X11/xorg.conf.d/20-intel.conf* with this content: *Section "Device"** ** Identifier "Intel Graphics"** ** Driver "intel"** ** Option "Backlight" "intel_backlight"** **EndSection* Finally, modify the startup script to adjust the initial brightness level: *echo -n 700 > /sys/class/backlight/intel_backlight/brightness** *Now my system starts with the right brightness level (the one I choose) and resume from suspend also by keeping the same brightness intensity. Problem solved! *** *Best regards, -- Marco Calistri Build: openSUSE Tumbleweed 20230225 Kernel: 6.1.12-1-default - XFCE: (4.18.1)

Yes, it may need quirks in kernel to prefer native backlight driver.
