I've found out some information but still can't work how to do what I want.

This page explains that the tvservice doesn't work on pc's its just a hack to stop crashing.

I found this on the wiki detailing how to change the display resolution.
https://github.com/recalbox/recalbox-os/wiki/Change-display-resolution-on-x86---x86_64

This is a global change and I would like to be able to set a per emulator resolution. I imagine this could be done using a launch shell script to call xrand and then open the emulator.

How does recalbox do this normally?
Is there any way to edit the existing launch commands to insert an xrand command?

Running the 64 bit image on a Gigabyte brix mini pc. My issue is that everything tries to run at 1080p some of the more power hungry emulators struggle to be stable at that resolution.

I've tried using the n64..videomode=DMT 35 and various other settings. All that happens is that it doesn't start up.
Nothing seems to work, and when I try to use tv service it always optputs this..

[
{ "code":1, "width":1920, "height":1080 }
]

regardless of what parameters i feed in. Any ideas why this is happening? And how to solve it?

I'm using the latest stable version 18.07.13. The scraper does work over Wi-Fi so its not totally broken. My main issue is when I turn on wifi I get random hanging and crashes after a while so after a short while it hangs and scraping is lost.
I get no crashes when plugged into ethernet with wi-fi off and network screen shows connected and an IP address but it just wont scrape. It seems whatever scraper settings are set up for wifi just need to be transferred to eth0

When I turn off Wi-Fi and use the scraper it always fails. It goes through all the games really fast as if every request fails instantly.

It does kind of work when I turn on the Wi-Fi and disable ethernet but the Wi-Fi is unstable and seems to cause the whole system it to hang quite often requiring a hard reset. (Despite being right beside the router)

I suspect that the ethernet config is somehow wrong for the scraper because SSH and web manager work fine via ethernet only. Have had a look at the ifconfig info which seems fine. Not sure where to look next to try to figure out why this is happening?

System is running on a gigabyte brix micro pc.
