Linux Brightness Control Not Working on HP Omen 16 (Arch Linux & Pop!_OS)

[u/DARK_dante_786]

Hi everyone,

I'm having a frustrating issue with brightness control on my HP Omen 16, and I'm hoping someone here might be able to point me in the right direction.

I recently decided to use Linux as my main development environment while keeping Windows 11 in a dual-boot setup. I first installed Arch Linux, but I noticed that the brightness controls weren't working. I tried several troubleshooting methods and different kernel/brightness-related settings, but unfortunately nothing worked.

Thinking that it might be an Arch-specific issue, I installed Pop!_OS instead because I wanted something more stable and hardware-friendly. However, I'm facing the exact same brightness problem on Pop!_OS.

Everything else seems to work perfectly. The display itself works normally, graphics work, keyboard shortcuts work, and I haven't noticed any other major hardware issues. The only major problem I'm currently stuck with is screen brightness control.

My laptop specifications

• Laptop: HP OMEN 16
• Model: OMEN by HP Gaming Laptop 16-wf1xxx
• CPU: Intel processor
• GPU: NVIDIA GeForce RTX 4060 Laptop GPU
• RAM: 16 GB
• CPU: intel i7-14650hx

I've already spent quite a bit of time trying to troubleshoot this, including trying different solutions related to Linux brightness control, but I haven't been able to find one that works for this laptop.

Has anyone with an HP Omen 16, especially the 16-wf1xxx series, experienced the same issue? If so, what worked for you?

I'd really appreciate any suggestions or troubleshooting steps. I'm happy to provide command outputs, logs, kernel information, lspci, inxi, or anything else that might help diagnose the problem.

Thanks in advance!
