Gaming laptops with dual GPUs are common, and they are a pain on Linux. I run an ASUS Zephyrus G15 with an AMD integrated GPU and an NVIDIA discrete GPU. Before I fixed the setup, I dealt with broken resume from suspend, terrible battery life, overheating, and games that ran worse than they should.
This is a practical guide for setting up dual GPU systems in Hyprland. Most of it applies to other Wayland compositors too.
Step 1: Set the iGPU as primary
Hyprland uses the AQ_DRM_DEVICES environment variable to decide which GPU drives the display. You want the iGPU first for power efficiency and better Linux compatibility.
First, find your GPUs:
lspci -d ::03xx
My output shows an RTX 3060 at 01:00.0 and an AMD Vega at 06:00.0. Create udev rules to symlink these to friendly names:
/etc/udev/rules.d/igpu-device-path.rules:
KERNEL=="card*", KERNELS=="0000:06:00.0", SUBSYSTEM=="drm", SUBSYSTEMS=="pci", SYMLINK+="dri/amd-igpu"
/etc/udev/rules.d/dgpu-device-path.rules:
KERNEL=="card*", KERNELS=="0000:01:00.0", SUBSYSTEM=="drm", SUBSYSTEMS=="pci", SYMLINK+="dri/nvidia-dgpu"
Reload rules:
sudo udevadm control --reload-rules
sudo udevadm trigger
Then tell Hyprland to prefer the iGPU:
env = AQ_DRM_DEVICES, /dev/dri/amd-igpu:/dev/dri/nvidia-dgpu
Step 2: Fix hardware video decoding
Without hardware decoding, video playback burns CPU, drains battery, and stutters at high resolution. Check if your system already supports it:
sudo pacman -S libva-utils
vainfo
If vainfo fails or picks the wrong GPU, set the driver explicitly. For AMD, add to hyprland.conf:
env = LIBVA_DRIVER_NAME, radeonsi
Common driver names: NVIDIA uses nvidia, AMD uses radeonsi, Intel uses i965 or iHD.
Step 3: Switch between Hybrid and Integrated mode
For gaming, you want both GPUs active. For battery life, you want the dGPU completely off.
sudo pacman -S supergfxctl
supergfxctl -s # list supported modes
supergfxctl -g # check current mode
supergfxctl -m Integrated # iGPU only, saves battery
supergfxctl -m Hybrid # both GPUs, for gaming
That covers the essentials. I wrote a longer post with full hyprland.conf snippets, troubleshooting tips for NVIDIA-specific quirks, and screenshots of the setup: How to Setup Dual GPU Systems in Hyprland.
