I think it would work, however for machines that will probably not have a monitor nearby ( a firewall / router /) network termination device... having console access is sufficient.. also there is a risk that someone would remove the hdmi dummy plug...
remember you can always renable inteldrm and reboot and it should work as before (with latency spikes)... there probably needs to be a look at why the inteldrm is spiking but that is above my pay grade... one can see the difference with smokeping quite vividly although Im happy to do a ktrace on inteldrm if that would help the driver support folks Thanks On Fri, 12 Sept 2025 at 22:21, <[email protected]> wrote: > > On Fri, 12 Sep 2025 02:58:44 +0100 > Tom Smyth <[email protected]> wrote: > > > the issue is the DRM seems to spike because there is no hdmi monitor > > attached to the router, > > > > Would an HDMI dummy plug suffice?
