MMM-MMM-Remote-Control monitor problem

[off112]

Hi,

I can’t turn on my monitor after I upgraded to debian buster.
I tried to change the node_helper.js to:

let monitorOnCommand = (this.initialized && "monitorOnCommand" in this.thisConfig.customCommand) ?
                this.thisConfig.customCommand.monitorOnCommand :
                "vcgencmd display_power 1";
            let monitorOffCommand = (this.initialized && "monitorOffCommand" in this.thisConfig.customCommand) ?
                this.thisConfig.customCommand.monitorOffCommand :
                "vcgencmd display_power 0";
            let monitorStatusCommand = (this.initialized && "monitorStatusCommand" in this.thisConfig.customCommand) ?
                this.thisConfig.customCommand.monitorStatusCommand :
                "tvservice --status";

But I can only turn off the monitor, not turn it on again. Is there a fix to this problem?

Does this work from command line (via ssh with screen off)

vcgencmd display_power 1

For some reason it started to work.

But I’m not sure how to do to get the monitor status to work.

I have tried to make these changes. But it doesn’t work:

  monitorControl: function(action, opts, res) {
            let status = "unknown";
            let monitorOnCommand = (this.initialized && "monitorOnCommand" in this.thisConfig.customCommand) ?
                this.thisConfig.customCommand.monitorOnCommand :
                "vcgencmd display_power 1";
            let monitorOffCommand = (this.initialized && "monitorOffCommand" in this.thisConfig.customCommand) ?
                this.thisConfig.customCommand.monitorOffCommand :
                "vcgencmd display_power 0";
            let monitorStatusCommand = (this.initialized && "monitorStatusCommand" in this.thisConfig.customCommand) ?
                this.thisConfig.customCommand.monitorStatusCommand :
                "vcgencmd display_power";
            if (["MONITORTOGGLE", "MONITORSTATUS", "MONITORON"].indexOf(action) !== -1) {
                screenStatus = exec(monitorStatusCommand, opts, (error, stdout, stderr) => {
                    if (stdout.indexOf("display_power=0") !== -1 || stdout.indexOf("0") !== -1) {
                        // Screen is OFF, turn it ON
                        status = "off";
                        if (action === "MONITORTOGGLE" || action === "MONITORON") {
                            exec(monitorOnCommand, opts, (error, stdout, stderr) => {
                                this.checkForExecError(error, stdout, stderr, res, { monitor: "on" });
                            });
                            this.sendSocketNotification("USER_PRESENCE", true);
                            return;
                        }
                    } else if (stdout.indexOf("HDMI") !== -1 || stdout.indexOf("true") !== -1) {
                        // Screen is ON, turn it OFF
                        status = "on";
                        if (action === "MONITORTOGGLE") {
                            this.monitorControl("MONITOROFF", opts, res);
                            return;
                        }
                    }
                    this.checkForExecError(error, stdout, stderr, res, { monitor: status });
                    return;
                });
