Do I see that correctly that your laptop does not have an integrated gpu? I find that nigh unbelievable. Could you please run sudo mhwd -li and lspci -v and post the output?

You’re right, it does have an iGPU, but in my BIOS boot menu there is an option to select between discrete graphics and switchable graphics, and for now I just have discrete graphics selected.

I think the no USB config could be related to a Possibly missing firmware for module: xhci_pci warning I get when the kernel builds with mkinitcpio? Not sure if it’s related to this issue, however.

I have this section:
Section "Extensions" Option "COMPOSITE" "Enable" EndSectionin my
/etc/X11/mhwd.d/nvidia.confas well. -
What’s the output of:
ls /sys/class/backlight
-
That section is in there for me too, I think. It’s the second to last section
-
In /sys/class/backlight there is a symlink to this
acpi_video0folder at/sys/devices/pci0000\:00/0000\:00\:01.0/0000\:01\:00.0/backlight/acpi_video0/, the contents of which are:
acpi_video0/actual_brightness:100
acpi_video0/bl_power:0
acpi_video0/brightness:100
grep: acpi_video0/device: Is a directory
acpi_video0/max_brightness:100
grep: acpi_video0/power: Is a directory
acpi_video0/scale:unknown
grep: acpi_video0/subsystem: Is a directory
acpi_video0/type:firmware
As I was meaning to say earlier, the value in the /sys/class/backlight/acpi_video0/brightness file (and the actual_brightness file) will change when I change my brightness via function keys or the sys tray slider, but my screen stays at 100% brightness. And I have a similar ideapad folder linked there after rebooting with the acpi_backlight=vendor Grub command-line option, with similar problems.

(included my output to speed things up.)
Hello, i have the exact same problem here with a similar environment (same Lenovo Legion laptop + Nvidia + XFCE), similar configuration files (main difference is that i’m using kernel 5.4) and same content in /sys/class/backlight when using acpi_backlight=vendor.
Did you manage to fix it ?
Is there a way to rename the /sys/class/backlight/ideapad to nvidia_0 ?
I could not use mv or ln -s on it.
I notice a version mismatch between mhwd -li (which gives video-nvidia-440xx) and the driver i am supposed to be using (linux54-nvidia-450xx). Could it be related to the issue ?
Hello,
After my manjaro updated today screen brightness seems to be set to maximum and neither my keyboard nor the slider under setting works anymore.
Here are some infos on my machine. If you need more I’ll try to deliver it.

Hope this information will be of any help! Currently, the only fix (for now) is simply going back to 5.8.18-1. Having both 5.8.18-1 and 5.9.8-2 installed keeps the same problem.
If you need even more information, I’ll happily oblige!
Just updated to Kernel 5.9.10-1 and I also can’t adjust screen brightness anymore. Indicator is showing and moving when trying to do so using keys, but brightness won’t adjust. Same goes for trying via tray icon slider. Screen turns black when I set brightness to 0%, though.

running in: konsole inxi: 3.1.08Just checked it myself and my laptop does the exact same thing when setting it to 0%. Does your laptop also boots with 100% brightness when you have it plugged in? And about ~20% when running on battery?
Same problem on T480 with KDE on 5.9.10-1, booting up 5.4 solved the issue for now.
So I had put my problem into this thread: [Stable Update] 2020-11-22 - Kernels, Pamac, Gnome, Jade, OnlyOffice, Xorg-Server - #20 by philm
And it was split by @Yochanan into a new thread: Screen brightness issues
In this new thread a solution was offered that did work for me!
Hopefully this fix will work for others as well! Many thanks to @Jack1221 
!
[EDIT] And yes, this solution works for the 5.9.10-1 kernel.
I have the same problem, but none of the solutions presented above helped.
The following did help
´´´
In the file /etc/default/grub change
GRUB_CMDLINE_LINUX=“acpi_osi=Linux acpi_backlight=vendor”
to
GRUB_CMDLINE_LINUX=“acpi_osi=Linux acpi_backlight=0”
´´´
I tried to make it more readable with 3 backticks, but I have no idea what a backtick is and where I would find it on my Belgian azerty keyboard.

@mbbs1024 here: `
Or you can just select the text and press Ctrl+Shift+C or the </> (preformatted text) icon.
Thanks for the tip on formatting.
For Lenovo Y540 (using Manjaro KDE) I’ve managed to fix it.
I’ve edited /etc/default/grub file to look like this
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3 acpi_backlight=vendor"
GRUB_CMDLINE_LINUX="reboot=acpi"
I’ve also edited /usr/share/X11/xorg.conf.d/10-amdgpu-nvidia-drm-outputclass.conf by adding this line to the Nvidia OutputClass section
Option "RegistryDwords" "EnableBrightnessControl=1;"
Working file looks like this
Section "ServerLayout"
Identifier "layout"
Option "AllowNVIDIAGPUScreens"
EndSection
Section "OutputClass"
Identifier "AMDgpu"
MatchDriver "amdgpu"
Driver "amdgpu"
EndSection
Section "OutputClass"
Identifier "nvidia"
MatchDriver "nvidia-drm"
Driver "nvidia"
Option "AllowEmptyInitialConfiguration"
ModulePath "/usr/lib/nvidia/xorg"
ModulePath "/usr/lib/xorg/modules"
Option "RegistryDwords" "EnableBrightnessControl=1;"
EndSection
Alternative way:
I’m currently using the optimus-switch-sddm tool to switch between GPU’s and on Nvidia driver, my /etc/default/grub file looks like
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3"
GRUB_CMDLINE_LINUX="reboot=acpi"
it was also working with
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3 i915.enable_dpcd_backlight=0"
GRUB_CMDLINE_LINUX="reboot=acpi"
and I also added
Option "RegistryDwords" "EnableBrightnessControl=1;"
to the /usr/share/X11/xorg.conf.d/10-amdgpu-nvidia-drm-outputclass.conf to the the Nvidia OutputClass section as above.
Additional info
After some updates /usr/share/X11/xorg.conf.d/10-amdgpu-nvidia-drm-outputclass.conf was overwritten so I had to edit it again.
Don’t forget to run it after editing the grub file
sudo update-grub

I had the very same problem BUT in my case loading kernel 5.7 instead of 5.9 fixed the issue for some time. Today there was an update that removed kernel 5.7, so the problem was back for me since 5.8 and 5.9 kernels both have the issue, I’ve tried to install and load the latest kernel 5.10 and the problem is fixed for me…
Dude, I don’t understand how you works…
You create the link “nvidia_0” or you always have it???
for me, I don’t have “nvidia_0”, and my “mhwd --listinstalled” looks not good.
I have no idea how to fix this problem, but I think yours are the most closed solution, could you list more detail?
Means you do not have the nVidia drivers installed or you don’t have an nVidia card.
Start here:
https://wiki.manjaro.org/index.php/Configure_Graphics_Cards
and if that doesn’t help, open a new topic and provide more information:
and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Hi,
I’ve done the first modifications you sugested on the grub file and now my system won’t boot !
I havent do “sudo update-grub” that you recommended at the end, because I’ve only see it after doing the modifications and as the screen brightness was still no changing, I tried to reboot.
Do you how can repair my boot ?
