somewhere before commit 496322b (yesterday's kernel) resolution
switching on my laptop broke. The screen switches to the right
resolution but the screen is not horizontally centered. The screen is
aligned left and the last vertical line is repeated until the right side
of the screen. Normally there would be black bars on left and right side.
