Bug ID: 217026
Summary: Backlight control broken on kernels 6.1.4+
Product: ACPI
Version: 2.5
Kernel Version: 6.1.11
Hardware: AMD
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ACPICA-Core
Assignee: acpi_acpica-c...@kernel-bugs.osdl.org
Reporter: albimarini4...@gmail.com
Regression: No
Brightness control does not work with AMD Ryzen 5800H when using hybrid
graphics on kernel updates 6.1.4+. I am using a Lenovo Legion Slim 7 (2021,
15ACH6) currently running Arch Linux with the mainline kernel 6.1.11, however,
I have been testing my experience with this issue on every point revision from
6.1.3 to 6.1.11.
CPU: AMD Ryzen 5 5800H with Radeon Graphics
GPU: NVIDIA RTX 3060 Mobile / Max-Q (Proprietary NVIDIA driver, tested
with 525.78.01-1 (version prior to 6.1.4 being released) and 525.89.02-1
(latest driver at time of writing))
System Memory: 40 GB
Display: Laptop (Laptop Screen)
The only parameters applied at boot on my system are: nvidia-drm.modeset=1
How to reproduce the issue:
Enable hybrid graphics/Optimus in BIOS setup.
Prior to kernel version 6.1.4, /sys/class/backlight contained two entries:
amdgpu_bl0 and nvidia_wmi_ec_backlight
With these two entries in /sys/class/backlight , I was able to write to their
respective brightness files directly or use a program like light to change the
values. Those values would change the brightness of the screen depending on if
I was using the AMD GPU or NVIDIA GPU to display the current application. I
could set these values to roughly the same thing to achieve an overall complete
brightness experience regardless of whether or not I was currently running an
application on my integrated (AMD) GPU or dedicated (NVIDIA) GPU.
Then, upon updating to kernel versions 6.1.4+, there is no longer an amdgpu_bl0
entry in /sys/class/backlight , just a nvidia_wmi_ec_backlight entry, making it
impossible for me to change the brightness on my display when using the iGPU.
Interestingly, on kernels 6.1.4+, running "journalctl -b -0 | grep backlight"
returns an output "amdgpu: [drm] Skipping amdgpu DM backlight registration",
which was not present in prior kernel versions.
However, if I instead prepend the option "acpi_backlight=native" to my kernel
command line options at boot, "amdgpu_bl0" is once again present in
/sys/class/backlight but "nvidia_wmi_ec_backlight" has now disappeared and is
nowhere to be seen making it so I can change the brightness when using the
iGPU, but the brightness is stuck at max when using the dedicated GPU. Running
the above journalctl command at this point returns no errors relating to my AMD
GPU and does not mention anything about the NVIDIA GPU. Trying different
acpi_backlight options on 6.1.4+ does not fix the issue and instead removes
functionality.
acpi_backlight=vendor makes an entry called "ideapad" pop up in
/sys/class/backlight with nothing else. Changing the brightness values in
ideapad does nothing.
acpi_backlight=video makes only two entries appear in /sys/class/backlight,
acpi_video0 and acpi_video1. Changing the brightness values in either of these
directories does nothing.
acpi_backlight=none causes nothing to appear under /sys/class/backlight.
If hybrid graphics is disabled, the display is connected to the NVIDIA GPU and
/sys/class/backlight/nvidia_0 is present, the NVIDIA driver can change the
display brightness without a problem.p
Below is my lscpi -nn and dmidecode outputs on kernel 6.1.3 and 6.1.11.
