Every time I start armbian I have to reboot the monitor or unplug the HDMI cable monitor to display

[dacen 0]

My board is rockpi4b

After starting, unplug or restart the display, the display will display armbian desktop directly, indicating that armbian is started normally, but there is no normal signal to the display.After restarting, you must switch the monitor power or unplug the hdmi cable to display.

This is not a problem if you use the official debian of rock and the armbian5.67 downloaded from rock's official website.

 

And i want to use gpio lib in armbian such as libmraa ,how should i do?

I have problem with HDMI on my rockpi4a, too.

Well, we don't want to maintain yet another RK3399 source ... some investigation and cherry picking from https://github.com/radxa/kernel/commits/release-4.4-rockpi4 might perhaps solve this issue.

so if i want to use armbian official image i must face this problem ?
