| # /etc/udev/rules.d/80-nvidia-no-suspend.rules | |
| # Prevent the NVIDIA dGPU from entering runtime suspend. This is needed for external | |
| # display ports (HDMI, DP) that are wired to the NVIDIA GPU. When the GPU runtime-suspends, | |
| # its connectors are disabled and it cannot detect that a monitor was plugged in. | |
| # So the hotplug event in 99-force-hotplug.rules would never fire. This rule keeps | |
| # the GPU awake so detection works. | |
| # /usr/lib/udev/rules.d/60-nvidia.rules sets power/control=auto on "bind", which suspends | |
| # the GPU and disables its connectors. We match "add|bind" to override that. | |
