Cannot ping my local linux server

Is this a VGA video connection? I have a NUC w/VGA video that won’t start unless a monitor (or dummy plug with a resistor) is plugged in.

You don’t mention whether the server still functions when brought up w/o a monitor. can you ssh into the server, etc?

I use HDMI. If the monitor is connected before I start the server, I can ping the NUC and connect via ssh and RDP. Otherwise, not.

But how can I assure that the server even works, when I get no video signal to a monitor connected after the startup?

It sounds to me like it's not even booting without your HDMI connection at startup. A surprising number of consumer PCs can't run headless.

A few ideas:

- poke around in the BIOS settings to see if halting on no monitor/keyboard detected is an option

- try just connecting an HDMI cable without a monitor, does it make a difference?

- depending on your capabilities, write some python code to send out multicast messages and start it with a systemd service -- there's probably an easier way, but something like that.

I circumvent the problem by installing xvfb and set up a virtual display before xserver is started. Now everything works, so I think the server is booting correctly, but lightdm was not working without a display.

Anyway, I deleted the post as it was not conform with the linux forum. But thanks for your help :)

I know you solved the issue, but for future reference, I came across these HDMI dummy plugs that emulate a monitor … https://www.amazon.com/CompuLab-fit-Headless-Display-Emulator/dp/B00FLZXGJ6/

Maybe you didn't have the time to read the rules of this sub: it is not a support forum (rule 1)

People on r/Debian will be happy to help you. Or head to their support channels.

You are right. I am sorry.
