In Plasma Desktop 6.0, pressing the brightness key changes the brightness level by 5% each. The problem is that in a dark environment, when the monitor's brightness is very low, 5% is too big of a step. In the low brightness range, even 1% change makes a noticeable difference. That is, something like 0% is too dark but 5% is a bit too bright. I can use the mouse, click the brightness icon on the system notification, and drag the slider to set values like 3%, but pressing the keys is more convenient. So, I wonder what if pressing the brightness keys changes the value by 1%, if the current monitor brightness is below 5% or 1-digit.
Thank you for this feature request! It does sound like a reasonable suggestion, and I've wanted something in the middle of lowest and second lowest myself. A better approach to achieve this might be to have the scale in perceptual space, rather than absolute space, so that the changes correspond more closely to their effect on human perception; see bug 448459. Moving to the powerdevil component, which handles changing screen brightness.
This does seem like a reasonable request
Let's just make it configurable like the volume step is. Marking as a duplicate of Bug 443213. *** This bug has been marked as a duplicate of bug 443213 ***
