allow setting up brightness slider device per monitor

[shalevc1098]

i saw in the config you can change brightness with dms ipc call brightness increment 5 "" dms ipc call brightness decrement 5 ""

currently, there is a brightness slider allows changing the brightness for one device, but lets say i have two monitors, so if i pick one of them, it would pick that device for all of them, meaning if i want to change the brightness of my second monitor i would have to pick it up again. it would be nice if you could make that setting per monitor and not global like it is now. thank you

You mean in control center correct? That is done in 8bb2a64663936f24a1e94aee570916021d2fa7b6

Thank you, i would check that when the problem with the bar background color gets fixed and would let you know if this is exactly what i wanted or not😊

Okay i tested it and it is almost there, just want them to save for each monitor independently. For first monitor for example i want to select device1 and for the second device2 lets say.

I got back around to this: a25e929200d166c5ed98494247c3ac7839231dde

you ccan pin to the monitor you open it on.

Hi, would it be possible to support displays that have more than 100% brightness?

I can set the brightness via ddcutil, but dms brightness throws with a value greater than 100.

Example:

~
❯ ddcutil detect
busno=5. Monitor apparently returns -EIO for unsupported features. This cannot be relied on.

It should be possible but in the next release, current git
