How can I check Ubuntu to see if a Dummy Plug is plugged in/installed? I have remote terminal access and have to audit a handful of machines to see if they have them and/or an external monitor

Eh? What's a "Dummy Plug" in this context?

Gotta be one of those hdmi dongles that emulates a screen so that my damnable macos "servers" stayed at a sane resolution when I would vnc to them.
OP, I can't confirm from my laptop of this kind of device would show up in lshw, but that's worth a shot.

lshw shows nothing on it. And yes it's the HDMI dongle that tricks it into thinking there's a display installed so we can view video and other things that we can't see otherwise and it helps with the resolution for sure

So.... What's a "Dummy Plug"? Since you never answered.

I see. The only way to detect that is to identify one, specifically, and then get it's EDID information if it has any, and search for that, ultimately.

Basically, identify it, or mutiple in the case of multiple different potential EDID's they may (or may not) report... And literally script something to look specifically for that.
Yeah, not so easy.

well it was worth a shot lol. Thanks!

Are you familiar with next steps on this?

no - im not going to pursue it - all of these are remote machines and they may have different versions (we just got generic ones of different types from Amazon and some are HDMI, some are DP, and some are mini-Dp)
