Struct KdeModeListV2 

pub struct KdeModeListV2 { /* private fields */ }

a list of custom modes

This list is populated by first setting each relevant property, and then calling add_mode to add a mode with these properties. One would for example call

• set_resolution
• set_refresh_rate
• set_reduced_blanking
• add_mode

add_mode does not reset the properties that were previously set, they are valid until the object is destroyed. The compositor may additionally have sensible defaults for some properties like reduced_blanking, but for consistent results, it’s best to always set each known property every time.

One can also specify custom modes with CVT timings, for example

• add_cvt
• add_cvt

The parameters resolution and refresh rate are required, if they are not set, the missing_parameters error will be emitted.

This interface has no events.

Implementations

impl KdeModeListV2

pub fn destroy(&self)

destroy the mode list object

pub fn add_mode(&self)

Add the current mode configuration to the list

pub fn set_resolution(&self, width: u32, height: u32)

pub fn set_refresh_rate(&self, rate: u32)

pub fn set_reduced_blanking(&self, reduced: u32)

whether or not the mode should have reduced blanking

Reduced blanking is an optimization that can reduce bandwidth / timing requirements for a display mode by reducing the time vblank takes. As not all displays support it, it may be desired to still turn it off though (like with CRTs, where full blanking is required).

pub fn add_cvt( &self, dot_clock: u32, hdisplay: u32, hsync_start: u32, hsync_end: u32, htotal: u32, hskew: u32, vdisplay: u32, vsync_start: u32, vsync_end: u32, vtotal: u32, vscan: u32, flags: u32, )

new mode with CVT timings

Adds a new mode with the specified CVT timings.
