Hi! First off, thanks for Omarchy. I just set up a new laptop with it and I'm really enjoying it 🙂

The laptop is an **ASUS ROG Zephyrus G14 GU405AW (2026)**: Core Ultra 9 386H (Panther Lake), an RTX 5080 Laptop GPU and an OLED panel, running Omarchy 4.0.4-1 on kernel 7.2.5-3-omarchy. While setting it up I hit three things that I think Omarchy could handle automatically for this model. I've included what fixed each one for me, in case it helps.

## 1. The laptop isn't detected as ROG, so `asusctl` doesn't get installed

This model reports its vendor slightly differently from older ASUS machines:

```
$ cat /sys/class/dmi/id/sys_vendor
ASUS
$ cat /sys/class/dmi/id/board_vendor
ASUSTeK COMPUTER INC.
$ cat /sys/class/dmi/id/product_family
ROG Zephyrus G14
```

`omarchy-hw-asus-rog` looks for `sys_vendor == "ASUSTeK COMPUTER INC."`, so the check fails here and `install/hardware/asus-rog.sh` skips `asusctl`. Installing it by hand works great. The battery charge limit and turning off the boot sound (`asusctl armoury set boot_sound 0`) both work fine.

Maybe the check could accept `ASUS` too, or look at `board_vendor`? Something like:

```bash
[[ $(cat /sys/class/dmi/id/sys_vendor 2>/dev/null) =~ ^(ASUS|ASUSTeK\ COMPUTER\ INC\.)$ ]] &&
  grep -q "ROG" /sys/class/dmi/id/product_family 2>/dev/null
```

## 2. Brightness keys don't change the brightness

The OSD shows up and `intel_backlight` changes (max 38400), but the panel brightness never changes. It's the same thing described in `install/hardware/asus/fix-asus-ptl-display-backlight.sh` for the B9406 and UX5406AA. Applying that fix (`xe.enable_dpcd_backlight=1`) solved it here too: max becomes 496 and brightness changes smoothly. It would be lovely if the G14 GU405 could be added to that script, maybe with `omarchy-hw-match "GU405"`.

One thing to be aware of: with that parameter, the screen stayed completely black at the LUKS password prompt. I could still type my password blind and it booted fine, but it was pretty confusing! I think the panel starts at zero brightness and only comes back once systemd-backlight restores it after root is mounted. A tiny initramfs hook right before `encrypt`, which writes 60% of `max_brightness` to `/sys/class/backlight/intel_backlight/brightness`, fixed it for me. So whatever turns the DPCD backlight on for these models will probably need something like that too.

## 3. YouTube in Chromium flickers with no picture

`default/hypr/nvidia.lua` sets `LIBVA_DRIVER_NAME=nvidia` whenever there's an NVIDIA GPU, including hybrid laptops like this one, where the Intel iGPU drives the display. Here `renderD128` is the NVIDIA card and `renderD129` is the Intel one, and YouTube just flickered black while the audio played.

What fixed it for me:
- `hl.env("LIBVA_DRIVER_NAME", "iHD")` in `~/.config/hypr/hyprland.lua`
- `--render-node-override=/dev/dri/by-path/pci-0000:00:02.0-render` in `~/.config/chromium-flags.conf`

Maybe Omarchy could skip the NVIDIA VA-API env when `omarchy-hw-hybrid-gpu` is true?

## Possibly related
- #5019: the same detection script misses TUF laptops, because of `product_family` there instead of `sys_vendor`.
- #11646: the same `xe.enable_dpcd_backlight=1` fix, on a Dell XPS with Panther Lake.

Happy to test anything or send more info if it helps. Thanks again!
