Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Size

mode size

This event describes the mode size. The size is given in physical hardware units of the output device. This is not necessarily the same as the output size in the global compositor space. For instance, the output may be scaled or transformed.

Fields

width: i32

width of the mode in hardware units

height: i32

height of the mode in hardware units

Refresh

mode refresh rate

This event describes the mode’s fixed vertical refresh rate. It is only sent if the mode has a fixed refresh rate.

Fields

refresh: i32

vertical refresh rate in mHz

Preferred

mode is preferred

This event advertises this mode as preferred.

Removed

the mode has been destroyed

The compositor will destroy the object immediately after sending this event, so it will become invalid and the client should release any resources associated with it.

Flags

mode flags

This event describes the mode’s flags.

Only available since version 19 of the interface

Fields

flags: WEnum<Flags>

Cvt

cvt timings

This event describes the CVT timings associated with the mode.

If an output mode has no CVT timings, this event will not be sent.

Only available since version 24 of the interface

Fields

dot_clock: u32

pixel clock in kHz

hdisplay: u32

horizontal display size

hsync_start: u32

horizontal sync start

hsync_end: u32

horizontal sync end

htotal: u32

horizontal total size

hskew: u32

horizontal skew

vdisplay: u32

vertical display size

vsync_start: u32

vertical sync start

vsync_end: u32

vertical sync end

vtotal: u32

vertical total size

vscan: u32

vertical scan

flags: u32

flags, see DRM_MODE_FLAG_*
