One post said I need to enable systemd. Seems that's done in the grub boot menu. Did that. Still didn't work.

Code: Select all

sudo systemctl status rc-local
● rc-local.service - /etc/rc.local Compatibility
     Loaded: loaded (/lib/systemd/system/rc-local.service; enabled-runtime; vendor preset: enabled)
    Drop-In: /usr/lib/systemd/system/rc-local.service.d

So no idea whats going on. I'm not going down the rabbit hole again just to autoload screen brightness. This should have been a standard option and simple to do since day 1 IMHO

Oh you're using Plasma desktop environment? I think those options are only available on the default MX desktop (XFCE)

Perhaps you need to do something like this for Plasma, ie; add a widget:

But I'm not an expert on Plasma at all, never used it personally.

If you ever have issues on one desktop environment, you can install another. Might be worth using the standard XFCE desktop with MX Linux since that's their main base, ie; 90% of users will default to that, and as such it will get more feedback and features are worked on there first.

I just read back in my old comments of this thread... I must be a fortune teller

The Plasma 5 applet Display Brightness Control solved this issue for me.

I installed it with this command:

plasmapkg2 -u risu.brightness.bar.v1.1.plasmoid
I can now change the display brightness from a KDE Plasma applet in the task bar.

I can't remember why I went for plasma, probably seemed easier and the best choice for me at the time. But if they are not developing it much.. it was kinda pointless choosing it then. I've had the same with desktop themes, I won't touch those as it WILL break the whole OS.

I tried the git you posted.. in the end..

Code: Select all

$ ddcutil detect
Open failed for /dev/usb/hiddev0: errno=EACCES(13): Permission denied
No displays found

This is why I just give up with software. After screwing with windows for 30 years getting stuff to work right, moving to Linux is like going a huge 30 year step backwards. I wasted enough years of my life the first time around. Plus I can't spent much time on the PC anymore due to my RSI. So rather than trying to reinstall the desktop, which will no doubt break everything I've setup already, I will just have to live with the annoyances I guess.
