Bug? PI400 and old 19"-monitor cannot be used for Armbian_22.11.0-trunk_Rpi4b_jammy_current_5.15.73_xfce_desktop.img.xz

Armbian_22.11.0-trunk_Rpi4b_jammy_current_5.15.73_xfce_desktop.img.xz 

Raspberry PI400

Viewsonic VP930 (1280x1024)

 

I checked the sha-sum and flashed 2 times a Patriot SXDC-128GB-card.

 

When I boot the PI400 the monitors LED changes from green (power on) to yellow (standbye) for half an hour, when I start the PI400. It looks like there is a problem with this old monitor which supports 1280x1024 only. Don't know, if the boot routine checks the monitor, but the green LED can stay for 2sec, sometimes for 30sec.

 

BTW Xubuntu 22.04 with an SSD works fine with the same hardware.

Same problem with Armbian_22.11.0-trunk_Rpi4b_jammy_edge_5.19.15_xfce_desktop.img.xz

Back again to stable: Armbian_22.11.0-trunk_Rpi4b_jammy_current_5.15.73_xfce_desktop.img.xz 

 

I cannot install with a Nec Multisync EA232WMi (FHD, 1920x1080) too

 

The monitor power led shows permanent on, the screen is black for 5-10 min.

 

So maybe the problem is the micro-hdmi dvi cable?

It is no problem to install 2022-09-22-raspios-bullseye-arm64-lite.img.xz, so I have no broken hardware, would be really happy to install Armbian 😉
