Curious from people who follow its development closely.
- What protocol are about to be finally implemented?
- Which ones are still a struggle?
- How many serious protocols are there missing?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I dont know what that means. Normally the monitor turns off when the PC stops sending a signal. In KDE i can easily configure when to dim, turn off, lock etc. the screen.
I needed to do that from the console, xset didn't work. As far as I could tell there was no other command.
What did you want to do?
A command to place the monitor in standby mode
What does this mean? Like unplugging without unplugging? Keeping one screen active and only turning off the other one?
I mean in the KDE monitor options I can choose [mirror,extend to left,extend to right,only external,only internal] so this is 100% possible.
Something like that yes, I want to turn off the side monitors with a single button press.
This will be possible and likely available as a command for your specific compositor. What are you using?
It was the one that came default with ubuntu 22.10 But as I have stated in my initial post, the feature had been restored by reinstalling Xwindow Also, I feel that the commands equivalent to
Should be the same regardless which wayland variant you are using.
No the implementations are per-compositor. The fact that this worked on X is due to.XOrg being a huge blob that every window manager relied on.
Look for the command in Mutter (GNOME), Kwin (KDE), or whatever DE you use.
That, is terrible
Its how Linux works lol. I mean there are tons of things per compositor.
The protocols are way cleaner and less, so it is easier for Distros to just write their own.
But for sure it is annoying that everyone wants to do their own. But that is not a Wayland problem, just nobody wanted to mess with XOrg.
Seems wasteful that each would need to build their own monitor power management interface.
They dont need to, a Desktop could just use another compositor and the rest of the stuff but they often dont.
wlrootsis a project doing some general work, but most of the others dont.Looks like it is hyprctl dispatch dpms on/off <hdmi_monitor_name> && hyprctl dispatch dpms on/off <main_monitor_name> Wlroots doesn't cover dpms
Also maybe via swayidle but I think dpms off, also triggers session lock
