Thanks to various posts on this forum, especially from aBUGSworstnightmare, I have something that works.
I then had to go into desktop preferences and check "Show identical desktop on second monitor".
To test, I added this to .config.wayfire.ini ...And verified with pinctrl that the backlight does indeed turn off, not just blanking the screen.
I also notice that there's an awkward approximately 1 second blink when the system first loads the backlight driver, when booting.
Is this a better solution than just adding a systemd service to sync with the DPMS signal? That's debatable.
I might see if I can figure out how to use the hdmi-connector in a device tree overlay. But I've already sunk enough time into this.
Code:
/dts-v1/;/plugin/;/ { compatible = "brcm,bcm2385"; fragment@0 { target = <&gpio>; __overlay__ { pwm_pins: pwm_pins { brcm,pins = <18 19>; brcm,function = <2>; brcm,pull = <0>; }; }; }; fragment@1 { target = <&pwm>; __overlay__ { pinctrl-names = "default"; pinctrl-0 = <&pwm_pins>; status = "okay"; }; }; fragment@2 { target-path = "/"; __overlay__ { backlight: backlight { compatible = "pwm-backlight"; pwms = <&pwm 0 500000 0>; brightness-levels = <0 255>; num-interpolated-steps = <255>; default-brightness-level = <255>; enable-gpios = <&gpio 27 0>; power-supply = <&vdd_3v3_reg>; }; }; }; fragment@3 { target = <&dsi1>; __overlay__{ status = "okay"; #address-cells = <1>; #size-cells = <0>; port { dsi_out_port:endpoint { remote-endpoint = <&panel_dsi_port>; }; }; panel_disp1: panel_disp1@0 { reg = <0>; compatible = "boe,tv080wum-nl0", "panel-simple-dsi"; backlight = <&backlight>; rotation = <0>; port { panel_dsi_port: endpoint { remote-endpoint = <&dsi_out_port>; }; }; }; }; };};To test, I added this to .config.wayfire.ini ...
