Holding down Fn and pressing the up and down keys is supposed to adjust the
brightness. A little box is shown in the middle of the screen with a
horizontal bar that indicates the brightness. That part still works. The bar
grows and shrinks, but the brightness is not affected.

All xbacklight commands I try (except for "xbacklight -help") cause the screen
to flash once and return zero. Even "xbacklight -get" causes a flash, prints
nothing, and returns zero.
