HP Victus new Vanessa installation backlight not working

[roblm]

You can load the nvidia_wmi_ec_backlight kernel module automatically during startup by adding it to the /etc/modules file. Open the file using this command: xed admin:///etc/modules
Add nvidia_wmi_ec_backlight at the bottom.

After doing that, you should test removing the amdgpu.backlight=1 parameter in the grub file.
After updating grub and rebooting, if you can’t change the brightness, then try a suspend/resume cycle.

The steps you have been trying are based on the article in this link provided previously by SMG:
https://lore.kernel.org/all/v_ODhOndx3g ... ail.com/T/

From reading other similar articles, the bug causing the problem should have been fixed in the 5.16 kernel, which has the nvidia_wmi_ec_backlight module.

You can try as a last resort using setpci, as described here, under the section: The more difficult method to fix the brightness: setpci
https://easylinuxtipsproject.blogspot.c ... html#ID4.3

Otherwise, you will need to wait for a kernel update that fixes existing bugs but your particular hardware may be less compatible with Linux.

Thanks roblm. I tried these workarounds under the hybrid graphics option. Adding the nvidia_wmi_ec_backlight module to the /etc/modules file loaded this module. However, even with the module loaded the backlight control continued to behave as before. With the amdgpu.backlight = 1 option in grub the laptop boots bright, without this option it boots dim, but in either case there was no control over the setting. Suspend/resume cycles did not change this behavior.

I also went ahead and tried the setpci method, both in hybrid graphics (nvidia on demand) and iGPU only (AMD power saving) modes. Retrieving the busID and then using it to set the brightness, as described in the link https://easylinuxtipsproject.blogspot.c ... html#ID4.3, executed all commands fine it seemed but did not actually alter the physical brightness of the screen from the value it booted up in. It just seems that, once booted, control over the brightness of the actual screen is not there. I suppose that is a driver issue.

The links were both informative, thanks for these references. I guess I'll wait on a kernel update.

[roblm]

I just remembered one other method you can try. Change this line in the grub file:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To this:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=! \"acpi_osi=Windows 2015\""

Then update grub and reboot.

If that doesn’t help, then try changing 2015 to 2012, and then try 2009.

What that does is enable the OS to report it is Windows instead of Linux. On some laptops, the BIOS checks to see if Windows is installed. If not, then some laptop functions may be disabled or not work well.

I tried the changes with no luck. One set of symptoms I haven't seen discussed is the Power Management battery settings. The display doesn't dim or go to sleep under battery power. It's probably just another set of related symptoms.

Hi roblm,

Thanks, I saw some references to this suggestion but have not tried it earlier. I edited the grub as suggested, but it caused my boot up sequence to hang after the grub menu was displayed. At the point where the LM logo normally comes on the screen stayed dark. I waited for at least a minute when usually the boot up to the login screen sequence is completed within about 10 seconds. So I just rebooted, adjusted the grub on the reboot, and then once the boot completed I set the grub back to original setting. There was what looked like possibly a relevant update this week, "xserver-xorg-video-amdgpu" was updated to version 22.0.0-1ubuntu0.1, but after installing it the brightness behavior is same as before. Laptop is still running the nvidia 510 driver, though now it is on AMD power saving mode, not hybrid. In any case, the actual brightness does not respond to function key input even though the "brightness" and "actual_brightness" files in /sys/class/backlight/amdgpu_bl0/ folder update with what looks like a correct numeric value representing the brightness setting (that is, values in the files go from minimum of 4 to max of 255 as I adjust it with the function keys up and down).

To OldGuy69, my laptop does go into sleep mode now when on battery, or even if plugged in. Originally I recall it just stayed on full all the time, but with the configuration now the power saving mode seems to transition to sleep OK. The remaining issues for me are that the brightness of the laptop screen cannot be adjusted, it is either bright or very dim depending on whether grub has amdgpu.backlight=1 or not (i.e. screen is bright if grub has GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.backlight=1"). Also, have not checked recently but suspect the HDMI output is still not working...but would have to confirm that. Work around through USB-C has been fine.

You could test the 5.19 kernel by using the Ubuntu Mainline Kernel Installer:
https://github.com/bkw777/mainline

Code: Select all

sudo add-apt-repository ppa:cappelikan/ppa
apt update
apt install mainline

Then open the Ubuntu Mainline Kernel Installer from the Menu > Administration and install the 5.19 kernel.

Just as an FYI, in this topic Screen Brightness the user with a AMD Ryzen 5 5500U with Radeon Graphics said they were able to change backlight when using Manjaro, but it was not working in Linux Mint. When I asked what kernel they were using in Manjaro, they said, "the latest stable i think" so a newer one may work for you, but I don't know which one that might be because I do not have a Manjaro install.

Downloaded and installed today, Manjaro 21.3.7 MATE comes with kernel 5.15.60, then updates to 5.15.65.

Thanks for the info. OP here has already tried 5.19.0-4.1-liquorix-amd64 and 5.17-oem so "the Manjaro kernel" looks like it is probably not a solution.

Hi all, appreciate the continued suggestions. I installed the latest 5.19.5 kernel, and tested it with the NVIDIA 510 driver either set to AMD (power saving mode) or NVIDIA (Performance Mode) to see if either made a difference. In both cases ls /sys/class/backlight/ shows just an amdgpu_bl0 folder, so I suspect the laptop is trying to control the screen brightness with the amdgpu driver regardless of what mode is set. No folder appeared when the NVIDIA (performance mode) was selected that would be associated to nvidia. So I suppose that amdgpu is the only driver for communicating with the screen on this machine.

Even with latest kernel, the brightness issue remains as before, that is, no actual control over the physical brightness. Whatever the issue is with the amdgpu driver and my particular hardware, its resolution so far does not appear to have made it into the kernel. Here is the inxi output in case it helps anyone also trying to track this down

Just as an FYI, in this topic Screen Brightness the user with a AMD Ryzen 5 5500U with Radeon Graphics said they were able to change backlight when using Manjaro, but it was not working in Linux Mint. When I asked what kernel they were using in Manjaro, they said, "the latest stable i think" so a newer one may work for you, but I don't know which one that might be because I do not have a Manjaro install.

This person just reported the just-released 5.15.0-48 fixed their issue. There are quite a few amdgpu and drm brightness fixes mentioned in its changelog. I do not know if it might help you or what fixes (if any) there might be for the 5.17-oem kernel.

[OmniZephyrus]

My friend really wants to install linux on the same laptop and is having the same issue.

Any luck with the new latest drivers that just came out? I have tried all the fixes and workarounds possibly anywhere for this issue and have not managed to assist him, if anything comes up please contact me!

Welcome to the forum, OmniZephyrus.
Have you tried the 6.0-oem kernel? You can install the latest 6.0-oem kernel with

Code: Select all

sudo apt-get install linux-oem-22.04b

and reboot.

[OmniZephyrus]

We live booted both mint and did that then tried garuda to make sure the absolute latest kernels and none worked sadly, my friend is getting really sick of windows spyware at this point and really wants to move, but cant because of this

[SMG]

We live booted both mint

You can not change a kernel on a live boot. The kernel loads at boot time and you can not reboot a live session. You can only reboot an installed version.

Also, since your last post, a 6.1-oem kernel became available which can be installed with sudo apt-get install linux-oem-22.04c (last letter changed).

I do not know if there might be newer AMD firmware available which might help. If you want to pursue that, please make your own topic on the issue and install Linux Mint. If your friend does not want to dual-boot to test, here is an option to consider Full Install to USB Drive: Four Options.
