Or is that complicating stuff too much? I'm not too keen on implementing all that when I have zero use for it. I can however rename the trigger for the existing fb_center_logo bool to fbcon=logo-pos:center and add a check for "top,left" to reset the bool to false. Then the other variants can be added later by whomever and when needed. Is that good enough? Cheers, Peter
