[Bug] General Question about Budgie Brightness Applet

[brent111]

Description

Actually a general question and not a bug that I know, please forgive me.

On my laptop Budgie (up to date) I have 3 adjustment tracks on the Brightness Controller Applet.
On my desktop Budgie (up to date) I have 2 adjustment tracks on the Brightness Controller Applet.
Both are Solus.

Why? Is there two versions or something? The laptop has much greater pinpoint brightness control while I struggle with the 2 tracks on the desktop.

How do I get the three-track package on the desktop budgie? Thank you.

Budgie version

10.9.2

Operating System

Solus 4.5

Steps to reproduce the issue

1. Open Brightness Controller on Budgie Desktop.
2. See a 2-track brightness controller
   1A) open brightness controller on budgie laptop
   1B) see a three-track brightness controller

Actual result

same budgies, two different brightness controllers

Expected result

same budgies, same brightness applet controllers

Additional information

If you are referring to the Budgie Brightness Controller Applet, it is provided by Ubuntu Budgie:
https://github.com/UbuntuBudgie/budgie-extras/issues

However...

The applet uses 3 sliders. Going off the top of my head here...

1. Backlight control
2. Gamma control using xrandr
3. Blue level using xrandr

I am guessing you are missing # 1 on your desktop, which uses what is in "/sys/class/backlight" to adjust the backlight level.
With an external monitor, you wouldn't have this type of backlight control the way you do on a laptop (at least not as far as I know).

Basically, this is expected behavior.

thanks for the detailed explanation, I really appreciate the knowledge. Brightness control is much better on laptop, perhaps you will 'port' this to the desktop version someday down the road. I will close this. Thanks again.
