Enum linuxfb::BlankingLevel

pub enum BlankingLevel {
    Unblank,
    Normal,
    VsyncSuspend,
    HsyncSuspend,
    Powerdown,
}

Represents a screen blanking level

See [Framebuffer::blank] for usage.

Note that not all drivers support all of these modes. In particular the VsyncSuspend and HsyncSuspend values may not be supported, in which case Normal behaves exactly the same as Powerdown.

Variants

Unblank

Undoes any blank, and turns the screen back on. Note that the picture is usually not retained while in blank mode, so you need to redraw everything after unblanking.

Normal

Blanks the screen, but leaves hsync/vsync running.

VsyncSuspend

Like Normal, but additionally suspends vsync

HsyncSuspend

Like Normal, but additionally suspends hsync

Powerdown

Blanks the screen and powers down sync circuitry as well.
