Monitor not waking up from sleep

[MadScientist]

Is the monitor really not turning on or does it just show a black screen. I have the problem that - very irregularly - I just get a black screen. I can move the mouse and see the cursor but the rest of the screen stays black. A ctrl+rrefreshes the site and and all modules are loading and showing up again. I couldn’t figure out what causes it (screensaver is disabled) but maybe it’s the same in your case? Have you tried to just refresh with ctrl+r and see what happens?

Hi, thanks for the tip. However, the monitor is definitely off. The monitors status LED is showing off, as if no input were connected.

I have tried restarting the mm server process through pm2, however, and that did not wake the display back up either unfortunately. I do have it set to DISPLAY :0 in the pm2 process script and it works and shows up for the first, say 6 hours of the day.

Actually, that makes me think that it works until my desktop is turned off, which makes the MMM-NetworkScanner execute MMM-Remotecontrol monitorOff action. That is that from which it does not “wake up”, I think!

I have tried the monitor on MMM-Remotecontrol action, and that did not work either unfortunately.

EDIT: My desktop has been on all day - so my monitor has not had to turn off, and lo and behold its still live when I got home today. Uptime = 13 hrs. This seems to confirm my theory that it is the MMM-RemoteControl “monitor off” action that it specifically is not waking back up from…

Hi @ndom91
tvservice isnt compatible with the KMS driver, you need to use fkms to retain that compativility

@cdelaorden hi thanks for the tip, we can ignore tvservice then. Any other way to troubleshoot what’s going on here or other toops for managing the HDMI connection?

@ndom91 try the fake KMS if you want to use TV service

It’s what I do
