In the settings menu of KDE Plasma I can set a brightness for the monitor. The brightness value I enter in the Plasma menu gets sent to the monitor.
Now, when I connect a monitor or boot the operating system, there are two possibilities. Either the last brightness value from the monitor memory is loaded by powerdevil into the Plasma menu or the last brightness value from the Plasma menu gets written by powerdevil into the monitor memory.
I would like a toggle for which of these two possibilities should be done . This toggle could be in the configuration file for powerdevil or it could be in the Plasma menu.
Because I would prefer that upon connection the last brightness value from the monitor memory gets loaded into the Plasma menu.
But others may prefer that upon connection the last brightness value from the KDE menu gets written into the monitor memory.
This toggle would be helpful for those who use one monitor for different devices or who use dual boot on a device.
