After booting there are leftovers of boot logs in the console. It is always a fixed number of lines. In console mode with the resolution of 640*480 it covers the whole screen leaving the console prompt completely out of bounds and I'm forced to use it blindly.
In graphics mode it covers only a little top section of the screen divided from the operational part of the screen by a purple line, however when the console becomes filled with text the prompt still goes out of bounds, so I'm still forced to operate half blind.
