Change Screen Resolution of .biosimg in GRUB

Hi Guys,

I’m in a bit of trouble with configuring the screen resolution of my .biosimg. It seems to be 640x480 by default but I can’t change it to 1920x1080x32 with gfxpayload or similar GRUB settings.

Do you can tell me what’s the proper way to configure it?

You can used a bbappend to,

To provide custom configuration to the grub.cfg file, eg adding kernel arguments.

I will try that now.
