On Ubuntu 19.10, there is a brightness setting on the power screen in settings. But it doesn't seem to do anything. You can slide it, but nothing happens. Anyone having luck adjusting screen brightness on Ubuntu?
We've tested on multiple machines, all seem the same. Both Nvidia and AMD cards same lack of adjustment.
Running 19.10 and I don't even have a brightness setting at all.
I have it, but it affects nothing.
Laptop or desktop monitor? I can't imagine it working on anything but a laptop.
That's why. I know of no OS that controls monitor brightness unless it's a laptop/tablet/phone/etc. Never an external monitor with separate power source.
Me either, but @CCWTech was asking for it. I've never looked for it before. No idea what it should do in that situation.
