Odroid n2+ using armbian cli hdmi loses signal after boot

[Rubiniuz]

Dear Armbian community I want to run klipper on my ordoid n2+ I started out using a default ubuntu os from odroid themselves but it was missing a ton of drivers I need. everything worked on that image except for the drivers.

 

Someone mentioned Armbian to me. I got everything running except I now have a new issue. I am using klipperscreen a simple gui with touch controls. before installing I could use my screen without issues and I installed everything on the screens terminal.

Now that klipperscreen is installed I see the boot sequence and than the signal gets lost. I already checked the klipperscreen guides and forums and if it doesnt report errors its the os doing weird dings with dpms or signal routing or something.

 

Does someone know why the screen suddenly just loses signal. when I uninstall klipperscreen I get it back.

 

I downloaded my os from here.

odroidn2

And this is my screen

any help or ideas are welcome. thanks in advance

So from help from github i am further with my research.

My display is still detected.

changing the boot.cmd and recompiling it and setting the armbianenv variables for display all to the best possible resolution and refresh rate doesn't change anything.

 

this is because there is a ghost display output which is set as primary:

 

I cant find any posts or documentation about disabling/removing this ghost screen. Or even changing the primary display output.

boot.cmd part 1

boot cmd part 2

changing hpd and edid to 0 to force my settings hasnt changed anything that's why i enabled them again.

armbianEnv.txt

These are the display i think chipsets or drivers.
