Summary0008616: Brightness slider not functioning on Kali Linux with XFCE4 desktop environment on MacBook Pro 2012 Retina Display.
Description

The brightness slider in the XFCE4 desktop environment on Kali Linux is not working on my MacBook Pro 2012 with a Retina Display. The issue persists regardless of attempting to increase or decrease the brightness using the slider. The problem is observed on Kali Linux version 6.5.0-kali3-amd64, running kernel 6.5.0-kali3-amd64 0000001 SMP PREEMPT_DYNAMIC Debian 6.5.6-1kali1 (2023-10-09) x86_64 GNU/Linux.
Steps to Reproduce:

Boot the system into Kali Linux with the XFCE4 desktop environment.
Open the brightness slider from the desktop environment settings or panel.
Attempt to increase or decrease the brightness using the slider.

Expected Behavior:
The brightness slider should adjust the screen brightness accordingly.

Actual Behavior:
The brightness slider does not have any impact on the screen brightness. The brightness remains unchanged regardless of slider adjustments.

Additional Information:

Operating System: Kali Linux 6.5.0-kali3-amd64
Kernel Version: 6.5.0-kali3-amd64 0000001 SMP PREEMPT_DYNAMIC Debian 6.5.6-1kali1 (2023-10-09) x86_64 GNU/Linux
Desktop Environment: XFCE4
Hardware: MacBook Pro 2012 Retina Display

Ask for support in the XFCE community instead of here?

From your description, it seems that you installed Kali on the MacBook (ie. not running in a VM)?

In that case, it seems that you're running into hardware support issue. You should try to do Internet search, not about Kali, but more generally about "Linux MacBook Pro 2012 Retina Display screen brightness" and see what comes up. Maybe it's a known issue. You can try to add "xfce" to your research, but I suppose that xfce doesn't do anything fancy, so if there's an issue, it's probably something more generic to Linux in general.

With that being said, sorry but there's nothing we can do, we don't have the bandwidth to troubleshoot hardware support issue. Hopefully the explanation and solution is out there on the Internet and you'll find it.
