Also, there are 3rd party apps that do the deed, an increasingly popular option is TwinkleTray but you can find more in a search engine. Source: 11 months ago

I don't think you can, since it automatically detects whether or not the screen is connected. Https://twinkletray.com/ tho this app can shut off the screen, maybe it can be better. Source: 12 months ago

Use this maybe? https://twinkletray.com/ I don't know if it will help. Source: about 1 year ago

TwinkleTray, to control display brightness on desktop displays like you can on laptops. Source: about 1 year ago

I develop Lunar that can do that for macOS, for Windows you have TwinkleTray and on Linux there's ddcutil. Source: over 1 year ago

Basically title, I see that https://glade.gnome.org/ from apt info glade points to an empty website. Source: about 1 year ago

The Glade website says that, as of August 2022, it's not being developed anymore and I remember reading an article somewhere (Phoronix?) saying that the GTK devs consider it deprecated and want you hand-writing GTKBuilder XML instead. I remember hearing several months ago that the GTK devs were deprecating Glade in favour of expecting people to hand-write GTKBuilder XML. Source: about 1 year ago

So, what's the best way to tackle the challenge: writing GNOME extensions + bind them to GNOME app, or GJS, or Glade, or something else? I thought about working directly with the specific tool's source code but then I realise it'll be just a waste of my time decoding the code written by somebody else for the sake of adding a few hundred lines of code that would still make just a miserable part of the original...

Can't argue with that, but to me it seems that things have substantially deteriorated since desktop GUIs fell out of fashion. Maybe that tells you more about my age than about the state of the art, but in the 90's one could "learn" GUI programming in about 30min in a RAD tool by throwing controls in containers and implementing callback functions in "direct style" for the event (Qt , swing, Java/ScalaFX, Gtk,...

I'm also learning Pyhton with GTK. I don't know if you already use GTK4 or if you decided to stick with GTK3 to be able to generate the xml file with Glade (drag and drop) because GTK4 isn't supported by Glade. That being said for GTK4 and python I found a very nice guide right here. Source: about 2 years ago
