Hey, I hope someone can help me.
Problem:
When I wake my PC from suspend, my monitor is always set down to 30% brightness for some reason.
These are the brightness settings of the monitor itself, which can only be accessed via the monitor settings using the buttons on the monitor. I do not mean the brightness settings of my desktop environment. These are still set to 100%, even though the monitor is darker.
The problem also arises in a second case. When I lower the brightness in the brightness control of my DE, my monitor brightness is also lowered in the monitor settings down to 30% again. I can then no longer increase the brightness in the DE settings, because 100% in the DE now equals 30% in the monitor. So if I set the brightness to 50% in the DE for example, this is 50% of the 30% set in the monitor. So actually only 15% in real terms
I hope I was able to explain the problem clearly. Please ask if you don’t understand something. It’s really annoying because I need to turn up my screen brightness with the Buttons on the Monitor every single time I wake up my PC.
Technical data:
- Nobara Linux 41 (Based on Fedora)
- KDE Plasma 6.3.3
- Wayland
- Desktop PC. So a external monitor. Not a laptop monitor.
- I have a 2nd monitor on which this does not happen.
I’ve got a relatively new Fedora install and I think I’ve seen this too - not had time to fully investigate, but have found on occasion if I leave it for a day the monitor brightness has wound down.
