I installed Manjaro XFCE but i am not able to adjust screen brightness. The brightness slider in power manager plugin doesn’t do anything. Also if i run ‘brightnessctl get’ in terminal it shows 0.

First thing I would check is to verify if it improves with another kernel.

Have you seen this?:
Different kernels might yield different results.
Also, the full inxi -zv8 might be more useful, in case someone else has got the same make and model and knows …
Tip
When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:
```
pasted text
```
Or three (3) tilde signs, like this:
~~~
pasted text
~~~
This will just cause it to be rendered like this:
Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.
Instead of like this:
Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.
Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.
Thereby increasing legibility thus making it easier for those trying to provide assistance.
For more information, please see:
As I’m a moderator on the forum, I have taken the liberty of doing this for you, this time.
Additionally
If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:
LC_ALL=C bluetoothctl
This will just cause the terminal output to be in English, making it easier to understand and debug.
Note that the above text is partially pre-prepared as a general introduction for new forum Users. Please take the time to to understand how it is done and encourage quality responses.

One more question (or two)
the answer to which could be useful:
Does it work when the machine is booted using the installer ISO (which you used to install from, or a recent one)?
Does it work with another distro perhaps?
… Mint, Debian, Ubuntu, what have you …
Same thing: just boot the installation medium and check the functionality, whether you can control the brightness there, whether it works “out of the box” there,

Page 9 of Laptop Manual shows keyboard function keys:
- Fn+F9 - decrease brightness
- Fn+F10 - increase brightness
Backlight keys not working in Xfce
In xfce4, the Xfce4 Power Manager handles the brightness keys.
In some installations of Xfce, the “Handle display brightness keys” setting may be turned off by default.
To activate the brightness keys again, open the Xfce Power Manager dialog and toggle on “Handle display brightness keys”:
xfce4-power-manager -c
Screen brightness can also be adjusted via Xfce power-manager panel plugin
xfce:xfce4-power-manager:panel-plugin [Xfce Docs]
This panel item provides a quick and easy way to see battery status, change display brightness, access Power Manager Settings and more.

The function keys for brightness do not do anything, and from manjaro live iso brightness also can not be adjusted.
I have to install another distro on other partition on my hard disk and see if brightness adjustment will work.
Instead, boot with whatever live environment is provided with “another distro” – this should achieve the same result without having to install other distributions.
Test in the live environment.
You might also consider downloading Manjaro Plasma and Gnome ISOs to test in the same fashion, for comparison.
If the same issue persists across distributions, I’ll suggest – tentatively – that there might be a hardware issue involved.
No.
The easy way:
Use a USB drive with Ventoy installed on it.
Then you can - just by copy/paste - put any ISO of any distro on it
and still use it for normal storage as well.
(as many as will fit on it, not just one at a time)
No need to actually install anything - just boot the installer ISO to check whether it works there “by default”
and just to be sure:
you saw that @nikgnomic mentioned that there is no single key, but a key combination?

As Ventoy was mentioned;
can brightness be adjusted via Xfce power-manager panel plugin?
Screen brightness might be tricky to control. On some machines physical hardware switches are missing and software solutions may not work well. However, it is generally possible to find a functional method for a given hardware. This article aims to summarize all possible ways to adjust the backlight.
the control method can be divided into these categories:
- brightness is controlled by vendor-specified hotkey and there is no interface for the OS to adjust the brightness.
- brightness is controlled by either the ACPI, graphic or platform driver. In this case, backlight control is exposed to the user through
/sys/class/backlightwhich can be used by user-space backlight utilities.- brightness is controlled by writing into a graphics card register through setpci.
ACPI
The brightness of the screen backlight is adjusted by setting the power level of the backlight LEDs or cathodes. The power level can often be controlled using the ACPI kernel module for video. An interface to this module is provided via a sysfs(5) directory at
/sys/class/backlight/.The name of the directory depends on the graphics card model.
ls /sys/class/backlight/
I tested with Linux Mint and MX Linux from live usb and brightness adjustment didn’t work on both neither using function keys combination or power manager slider. I guess it is hardware issue, though i have Windows 7 in stalled on another partition and brightness adjustment works on it.
You have an Nvidia GPU: Quadro 1000M
You are using the Nvidia linux proprietary driver: nvidia-390xx
To get brightness control working, given the above, add nvidia.NVreg_RegistryDwords=EnableBrightnessControl=1 to your linux command-line params, i.e. GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub if using grub, then run update-grub.
An alternative would be
# echo 'options nvidia NVreg_RegistryDwords="EnableBrightnessControl=1"' > /etc/modprobe/nvidia-brightness-control.conf

According to Archwiki, for this laptop you need nvidiabl
But it is only available as an extra module for kernel 5.4 in the repos, and sooner or later that kernel will be deprecated like the module itself. So it will be better if you find alternative method like for example the post above.
Edit: sorry, my search kungfu is not strong today. I missed this version from AUR.
Still, upstream is dead - GitHub - guillaumezin/nvidiabl: /!\ Please note that I don't maintain this repository anymore, please have a look at forked projects. /!\ so it is unclear how long will it work.
