- Add 20-dummy-headless.conf (Driver dummy, 1920x1080) - Remove 20-intel-virtual.conf (intel driver required HDMI at boot) - Update install.sh: installs dummy driver, saves EDID, updates GRUB - Update README: document dummy driver + kernel EDID fallback approach - hdmi-fallback.sh now detects DUMMY0 or VIRTUAL1 Rationale: intel VirtualHeads only worked when HDMI was connected at boot. Dummy driver creates DUMMY0 unconditionally, working with or without cable. Kernel EDID fallback (video=... drm.edid_firmware=...) is insurance if dummy fails.
