wlr output power management

Control power management modes of outputs

This protocol allows clients to control power management modes of outputs that are currently part of the compositor space. The intent is to allow special clients like desktop shells to power down outputs when the system is idle.

To modify outputs not currently part of the compositor space see wlr-output-management.

Warning! The protocol described in this file is experimental and backward incompatible changes may be made. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes are done by bumping the version number in the protocol and interface names and resetting the interface version. Once the protocol is to be declared stable, the 'z' prefix and the version number in the protocol and interface names are removed and the interface version number is reset.

Manager to create per-output power management

This interface is a manager that allows creating per-output power management mode controls.

get_output_power(id: new_id<zwlr_output_power_v1>, output: object<wl_output>)
Argument
Type
Description
idnew_id<zwlr_output_power_v1>
outputobject<wl_output>
Get a power management for an output

Create an output power management mode control that can be used to adjust the power management mode for a given output.

destroy()
Destroy the manager

All objects created by the manager will still remain valid, until their appropriate destroy request has been called.


Adjust power management mode for an output

This object offers requests to set the power management mode of an output.

Argument
Type
Description
modeuint<zwlr_output_power_v1.mode>
the power save mode to set
Set an outputs power save mode

Set an output's power save mode to the given mode. The mode change is effective immediately. If the output does not support the given mode a failed event is sent.

destroy()
Destroy this power management

Destroys the output power management mode control object.

Argument
Type
Description
modeuint<zwlr_output_power_v1.mode>
the output's new power management mode
Report a power management mode change

Report the power management mode change of an output.

The mode event is sent after an output changed its power management mode. The reason can be a client using set_mode or the compositor deciding to change an output's mode. This event is also sent immediately when the object is created so the client is informed about the current power management mode.

failed()
Object no longer valid

This event indicates that the output power management mode control is no longer valid. This can happen for a number of reasons, including: - The output doesn't support power management - Another client already has exclusive power management mode control for this output - The output disappeared

Upon receiving this event, the client should destroy this object.

mode { off, on } 
Argument
Value
Description
off0
Output is turned off.
on1
Output is turned on, no power saving
error { invalid_mode } 
Argument
Value
Description
invalid_mode1
nonexistent power save mode
