[Solved] Power Manager Can't Adjust Brightness

On Arch, Power manager brightness-slider has NO effect.
xbacklight reports "No outputs have backlight property"

I CAN adjust brightness with

echo 6000000 > /sys/class/backlight/intel_backlight/brightness

the following also works

xrandr --output LVDS-1 --brightness 0.9

i noticed xrandr applies a blue tint.
The echo command above doesn't apply any tint,
so i prefer a fix which works like the echo method (no tint).

When I applied the fix below, i could not startxfce4 at all. Stuck at terminal on boot.
i notice the file 20-video.conf didn't exist before i applied this fix:

If you get the "No outputs have backlight property" error, it is because xrandr/xbacklight does not choose the right directory in /sys/class/backlight. You can specify the directory by setting the Backlight option of the device section in /etc/X11/xorg.conf.d/20-video.conf. For instance, if the name of the directory is intel_backlight and using the Intel driver, the device section may be configured as follows:

/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "Backlight"  "intel_backlight"
EndSection

https://wiki.archlinux.org/index.php/Ba … xbacklight

Any fix?

Re: [Solved] Power Manager Can't Adjust Brightness

What is the make and model of your computer?

Can you post back the results of the following commands:

lspci -vnn | grep -A12 VGA
ls /sys/class/backlight/
cat /etc/X11/xorg.conf.d/20-intel.conf
cat /proc/cmdline

Re: [Solved] Power Manager Can't Adjust Brightness

What is the make and model of your computer? Do you have dual video cards?

If you could try the backlight fix (/etc/X11/xorg.conf.d/20-intel.conf) from above one more time and post back the Xorg.0/log or Xorg.0.log.old file (the latter if you've rebooted) when it fails. It should work for you and perhaps the log file might identify why it isn't.

Another thing you might want to try is the "acpi_backlight=vendor" or "acpi_backlight=none" kernel parameters. (See the Kernel command line options section of the same link above that you posted).
Specifically:

If you find that changing the acpi_video0 backlight does not actually change the brightness, you may need to use acpi_backlight=none.

(but I've seen the acpi_backlight=vendor parameter work before as well).

Gateway P-Series laptop (old)

not that i'm aware of

post back the Xorg.0/log or Xorg.0.log.old file (the latter if you've rebooted)

What's the sequence without rebooting? Don't i have to do something to make the new .conf take effect?

Re: [Solved] Power Manager Can't Adjust Brightness

If you tried the "/etc/X11/xorg.conf.d/20-intel.conf" file on your last boot, just post back your /var/log/Xorg.0.log.old file.

Re: [Solved] Power Manager Can't Adjust Brightness

i included both log files for good measure.
The old is the fail to startxfce4, the other is successfully ran startxfce4.
It seems the good one used some generic default drivers, correct?

Okay, so you are using the modesetting driver. When you created the "/etc/X11/xorg.conf.d/20-intel.conf" file you specified the intel driver, but you don't have it installed. That's why the boot failed.

There are 2 options:
1. Install the intel driver (something like xf86-video-intel) in your distro's repositories and try that file again,
2. Try the "acpi_backlight=none" and "acpi_backlight=vendor" command line parameters (separately, not both at once).

"command line parameters"?

You mean 20-video.conf?

No, kernel command line parameters. Have a read through this Ubuntu wiki document on testing and setting kernel parameters. Follow the "Temporarily Add a Kernel Boot Parameter for Testing" section twice - once to try the "acpi_backlight=none" parameter and once to test the "acpi_backlight=vendor" parameter. After each time you add a paramter and boot, test the brightness keys/slider. If they work, you've found the magic parameter. Then follow the "Permanently Add a Kernel Boot Parameter" section to make it permanent.

If neither of those work, then you can try the /etc/X11/xorg.conf.d/20-intel.conf method again with the intel driver installed.

Re: [Solved] Power Manager Can't Adjust Brightness

Unsure if i'm doing this right.

I created /etc/sysctl.d/99-sysctl.conf
acpi_backlight=none

then ran
sysctl --system

brightness controls didn't work.

Then tried same with
acpi_backlight=vendor

Still no control.

Also tried the following, which i think gets applied immediately, without further commands, correct?
# sysctl acpi_backlight=none       
sysctl: cannot stat /proc/sys/acpi_backlight: No such file or directory

# sysctl kernel.acpi_backlight=none   
sysctl: cannot stat /proc/sys/kernel/acpi_backlight: No such file or directory

Nothing worked.
Do i need to reboot?

thx!

Re: [Solved] Power Manager Can't Adjust Brightness

No, not like that.
Following the instructions from https://wiki.ubuntu.com/Kernel/KernelBo … or_Testing:

1. Restart your system, or shut it down and then power it on again.

2. As the system starts to boot repeated tap the Esc key in order to force the "GNU GRUB" menu to appear. For BIOS-mode (not UEFI-mode) booting a SHIFT key can be held down continuously until the menu appears. The "GNU GRUB" menu will look something like this:
(If the system hangs at the initial vendor logo screen when you hold down SHIFT, just release the SHIFT key briefly then hold it down again until the "GNU GRUB" menu appears. _

3. Once the "GNU GRUB" menu appears highlight the desired entry and press the e key to enter edit mode. The edit mode screen will look something like this:

4. Use the down arrow key to move the cursor to the line beginning with the word "linux", then press the END key to move the cursor to the end of that line. Normally this will be just after the words "quiet splash".

5. Press SPACE to add a blank space (after "splash") then carefully type in the kernel boot parameter that you need to add. (If you need to add multiple parameters separate them with SPACE but do not add spaces before or after any = signs or punctuation in the parameters themselves).

5. Press Ctrl+X to boot the system using the parameters you've added.

The screen shot images are at that link above to show you what it looks like,

Re: [Solved] Power Manager Can't Adjust Brightness

Both switches worked!
But only when I manually edited the live grub.

If I put into /etc/default/grub as instructed, has no effect.

Did you run "sudo update-grub"?

If so, can you post the contents of your /etc/default/grub file?

Re: [Solved] Power Manager Can't Adjust Brightness

Correction, permanence works.

To get control over brightness, via Power Mgr brightness-slider and keyboard brightness buttons (only on the OS which controls grub), i can do:

/etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=none"

I mistakenly ran grub update from the wrong OS.

SOLVED! Power slider and keyboard buttons work.
But xbacklight still not working. Still gives "No outputs have backlight property".

ArchLabs somehow gets xbacklight working upon install.

Which parameter did you use?

cat /proc/cmdline

How many backlight interfaces do you have?

ls /sys/class/backlight

Re: [Solved] Power Manager Can't Adjust Brightness

Hmm. xbacklight should work if there is only one backlight interface. Perhaps this is a bug with xbacklight?

Re: [Solved] Power Manager Can't Adjust Brightness

posts #10 and #12 are temporary.

How can i make it permanent for other OS? The values in  /etc/default/grub only affect the "main" OS (from which grub was installed and updated).

thx

Re: [Solved] Power Manager Can't Adjust Brightness

You need to add it to each of the different OS kernel boot lines in /etc/default/grub then run grub-update. This needs to be done from the main OS - the one that manages grub.

Re: [Solved] Power Manager Can't Adjust Brightness

Not sure about this (and out of the scope of this forum, I think), but see, from this document:

Custom Menu Entries

GRUB 2 allows users to create customized menu selections which will be automatically added to the main menu when sudo update-grub is executed. A 40_custom file is available in /etc/grub.d/ for use or to serve as an example to create other custom menus. Information on building and using custom menus in GRUB 2 is located in the Grub2/CustomMenus community document.

The corresponding Arch doc would be https://wiki.archlinux.org/index.php/GRUB

good luck

Re: [Solved] Power Manager Can't Adjust Brightness

Thx, @alcornoqui.

Problem with 40_custom is, it adds additional entries, without removing existing entries (the ones without "acpi_backlight=none"). So then you have two entries for the same OS, one with "acpi_backlight=none", and one without it.

Possible fix: The entire automatically-generated menu can be disabled. But then all entries have to be created manually.

That might not be too bad, if there was an easy way to copy the current auto-menu, and use that as a starting place for the custom menu. But that's a bit of work.

I took the easy way, and used Grub Customizer. That allowed me to add the kernel pararms to the existing menu entries, instead of adding extra menu entries. https://www.archlinux.org/packages/comm … ustomizer/

i'm wondering if "acpi_backlight=none" is always the preferred setting, on all hardware.
