• OS: Arch Linux
• Tmux Version: tmux 3.3a

Potential fixes

Adding a disclaimer that the user must have the proprietary drivers installed or adding support for the Nouveau drivers.

[shawarden]

Do the proprietary and/or non-proprietary nvidia drivers not create /sys/class/drm/card?/device/gpu_busy_percent ?

[ethancedwards8]

I can vouch that the open source nvidia drivers do not expose this interface.
