Hi all,
I recently re-installed Garuda Dragonized with KDE Plasma X11. I have 3 screens from different brands.
When I change screen brightness with the shortcuts on my keyboard, in the old installation all screens went from value X to value Y in 5% increments. In the new installation, starting at 0% for all screens, only one screen goes up until 20%, then the second one starts going up and when the first one is at 60%, the 3rd one starts going up. That results in different brightness values on all screens which is not really nice to work with.
I did not find a way to fix this within the settings or on the internet, went through the garuda forums and some Brave searches.
What can I do to fix this? What data is useful to troubleshoot this issue further?
I use an AMD graphics card + CPU and my system is up to date.
Thanks in advance for any help, much appreciated!
