OpenMediaVault won't load after update, where to dig?

Question

linux

There is a home server on OpenMediaVault 3. After the next update, the server started to hang when loading.
And the most ambush is that if you connect the monik to D-SUB, then everything is loaded normally. If you do not turn on the monitor, then the server hangs, and after that it is useless to connect the monitor - there will be a stupid black screen.
Of course, I understand that this is all Beta with all the consequences, but can this be somehow corrected? And then do not put the same monitor in the closet ...

Answer 1

Put a stub in dsub as an option if it's in the hardware
