+# omarchy:summary=Detect whether NVIDIA drives the display (rather than a hybrid iGPU).
+
+# On hybrid laptops the display is usually wired to the integrated GPU while
+# the NVIDIA card only handles offloaded rendering. Forcing NVIDIA's VA-API and
+# GLX drivers globally then breaks Chromium-based browsers (black video with
+# audio still playing), so the Hyprland NVIDIA env only applies when NVIDIA is
+# the display GPU.
+#
+# sysfs exposes which VGA device drives the display via boot_vga. When no
+# device claims it (attribute missing or unreadable), assume NVIDIA is the
+# display GPU to preserve the current behavior on machines we cannot tell.
+#
+# Read the cached sysfs IDs rather than lspci, which reads PCI config space and
+# resumes runtime-suspended GPUs.
