Solved: Re: Possible to run headless? - Page 2

Has anyone succeeded in running AMT systems headless, with no monitor cable attached?

Noticed that when there is no monitor cable connected, I do not get any visual with the KVM-over-IP either.

Once I do connect the monitor cable the missing visual appears instantly.

I do can access the BIOS and GRUB with kvm-over-ip, so might be a (Debian) Linux only issue.

(it's not the standard screen blanker. pressing a key doesn't solve it)

Micred,

The basic issue is that without something being plugged into a video port, the on board GPU gets shut down. Since the GPU is not displaying anything, all you get is a blank screen. You can use a display port or HDMI display emulator to resolve the issue you are seeing.

Gosh! from 2012 to 2024 it seems we still need this... I'm facing the same issue.

May be its time since the typical edge use cases would require an headless setup.

Please suggest if there has been some break throughs or workarounds that probably have fixed this issue

There are more people that have this issue than you think most of them end up using an edid faker (HDMI dummy).

But that will prevent the power saving of the GPU waisting energy.

What we need is a patch for the AMT that will wake up the GPU when an incoming connection is detected and keep the GPU active as long the session is valid.

Yes it ispossible Just use the right flags and config for the headless mode

Thank you for your comment. But since no one in this thread was able to get it working, it would be really apprechiated if you could give some pieces of advice. Any links to documentation of the flags you mentioned, some examples or at least tell us which flags you mean.
