@@ -51,6 +51,8 @@ The **org.freedesktop.ratbag1.Resolution** interface provides:
- XResolution -> uint for the x resolution assigned to this entry
- YResolution -> uint for the y resolution assigned to this entry
- ReportRate -> uint for the report rate in Hz assigned to this entry
- Maximum -> uint for the maximum possible resolution
- Minimum -> uint for the minimum possible resolution
- Methods:
- SetResolution(uint, uint) -> x/y resolution to assign
- SetReportRate(uint) -> uint for the report rate to assign
