Steam/Moonlight - Running games directly from EmulationStation

The only issue I’ve found with Pegasus-FE and moonlight is that HDMI blanks (i.e the HDMI signal completely cuts off) consistently after 10 mins of streaming. The stream however keeps running fine as audio is present and my controller still functions as normal.

It's the screensaver.

@mitu

Ah, gotcha! Is there a way to disable that? I assume with xscreensaver?

Yes, your desktop environment should have some settings to disable the screensaver or monitor blanking. What is your desktop env ?

I assume with xscreensaver?

I doubt it.

@mitu I’m using the standard LXDE package with the official RetroPie image, installed from RetroPie-Setup. I tried installing xscreensaver and disabling it that way but unfortunately the screen is still blanking... tvservice -p command brings it back to life so its definitely something to do with the blanking... despite it being disabled, strange...

Run

xset -dpms s off s noblank

after starting desktop session and before starting any program.

@mitu Hmm, unfortunately this didn't seem to work. I tried adding the below to the moonlight.sh script in the /opt/retropie/supplementary/moonlight directory, but it didn't seem to change anything... EDIT: Nvm, turns out the dpms commands wouldn't work for me unless I enabled it. See here: https://forums.linuxmint.com/viewtopic.php?t=329548

#!/usr/bin/env bash
export XDG_DATA_DIRS=/opt/retropie/supplementary/moonlight/share
export XDG_CONFIG_DIR=/opt/retropie/configs/all
export XDG_CACHE_DIR=/opt/retropie/configs/all
xset -dpms s off s noblank
/opt/retropie/supplementary/moonlight/bin/moonlight "$@" -audio default

After to speaking to the developer it seems that Pegasus-FE doesn’t run in an X11 environment but rather on top of Open GLES/EGL, so perhaps X11 commands don’t work here. Is there a way to pause it somehow using EGLFS that you’re familiar with? Perhaps xset commands have no affect...

This is the same display method used by EmulationStation, so there shouldn't be a difference here. Most likely Pegasus is not controlling the display video during a gameplay so I don't think it has any influence on how the display blanking is checked.

StonedEdge

@mitu Hmm, OK then. Well I'm a bit stumped... tvservice -p brings back the display entirely so it is definitely a HDMI related blanking problem.

@mitu

OK, finally figured it out!

Needed to add export QT_QPA_PRESERVE_CONSOLE_STATE=1 to the autostart file. It seems the consoleblank=0 gets overriden by Qt applications. Seems like a bit of an undesirable behaviour but glad it works now.
