Why my pve system can just work normally with a hdmi connection ?

[zkk000sflw]

I set up the PVE(The version is 6.2) under the cpu of j1900.And it can't work(It can't get into the system properly) unless I add a hdmi connection to it ..And, it need a hdmi connection when it just started .If for a few miniture ,It still didn't work unless I restarted it with hdmi connection ..

I searched for the syslog and debug for the question ,but it didn't work ,there is just blank .

just as these :
I shuted down it at about 15:36:02 and started it withoung hdmi connection during 15:37:00 to 15:40:00 ...And started it with hdmi connection at 15:45:18 successfully .



My machine is remoulded by a Rainbow graphics card, I dont't know if it's matter or not .

Looks like an hardware issue without any relation to Proxmox (and probably any other OS too). Try to install a simple Ubuntu server and check whether you have the same phenomenon.
