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.

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?

My first experience in wayland, us discovering I couldn't control monitor sleep/standby function. I found how to reinstall X and managed to escape it since.

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.

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

xset dpms force off
xset dpms force standby
xset dpms force suspend

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.

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.

[–] [email protected] 1 points 6 months ago (2 children)

They dont need to, a Desktop could just use another compositor and the rest of the stuff but they often dont. wlroots is a project doing some general work, but most of the others dont.

[–] [email protected] 1 points 6 months ago

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

[–] [email protected] 4 points 6 months ago (1 children)

That sounds like problem with specific software configuration, like missing packages in some distro or something being badly built. There’s nothing about Wayland that would prevent it from working.

[–] [email protected] 1 points 6 months ago (1 children)

Tried xset, not compatible. Tried searching equivalent command, there was none. That was in 2022.

[–] [email protected] 1 points 6 months ago* (last edited 6 months ago) (1 children)

Wayland is not a standalone server like Xorg and it doesn’t have standard utilities to control stuff like DPMS. That functionality goes to compositors that are effectively individual Wayland server implementations. Compositors can provide utilities to control display, and they usually do. For example, on KDE Wayland you can call kscreen-doctor --dpms off, wlroots compositors (Sway, Wayfire, Hyprland,…) have inter-compatible tools, like swaymsg output DP-1 dpms off. If that’s what you meant anyway.

[–] [email protected] 1 points 6 months ago

There really should be a front end script that has uniform command line parameters, finds what your compositor is, translate the command line arguments and send them.
