Default screen resolution 720x576 in Armbian 23.05.1

[perfstr]

Hello, I downloaded recent Armbian image for Orange Pi PC Plus - 23.05.1. When I run it, the screen resolution is 720x576 and virtual resolution 1024x768. I changed armbianEnv.txt - defined disp_mode=1280x800p60 (this is what I need) and also used fbset command in my application and it works in most cases, but sometimes after system restart the screen resolution is the default (720x576) and can't be changed - I get error - "ioctl FBIOPUT_VSCREENINFO: Invalid argument". How can this be fixed?

Thanks in advance.

Hi, I don't know, if this is relevant, but older version - 23.02.2 with Linux-5.15.93 works better about the resolution I need. Hope this helps.
