Thanx for the info. I'm not sure I understand the last sentence nor I'm
sure I'll ever need such thing it's only the white color that is a
little annoying, hence another question - is there a chance for the
"missing space" to not be white (and be black)? Is this something they
can do in that kernel framebuffer or do they need the white color to
catch the potentially lost stuff?
