With XWayland there is no urgent need for conversion. And "a lot of applications that just wouldn't load" sounds pretty fishy to begin with.

Old drivers have issues with XWayland. There's nothing fishy about that statement whatsoever. Hell, NVidia only JUST got XWayland working, though that's probably more an issue of corporate stubbornness.

I think NVidia have every incentive to oppose Wayland. The graphics and post-production studio market mostly uses NVidia Quadro cards on linux workstations. They choose NVidia because only NVidia has a fast, stable, minimal-artifact implementation of X11. Being able to code drivers for X11's crazy architecture is actually a competitive advantage.

If your home television supports Miracast, you can do it today: https://flathub.org/apps/details/org.gnome.NetworkDisplays

Wow, that's pretty crazy. I didn't know Wi-Fi Direct was already supported on (non-Android) Linux. It doesn't seem to establish a connection properly with my Intel 8265 card out of the box though. I'll have to play around with it a bit more.

You might be running into this: https://patchwork.ozlabs.org/project/hostap/patch/2020082506... if your distro doesn't ship this patch to wpa_supplicant (AFAIK Fedora does ship it).

This is very good. Not only because it illustrates the maturity of wayland, this is been done using pipewire. The last remaining pieces of the puzzle are finally being placed. A modern linux distro will give you on the desktop a good oomd, good video drivers, pipewire, wayland, GTK 4, GNOME 40, a modern kernel, compiler, dev-tools... and modern cross distro software through flatpak/snap/appimage. There are still thin…

> I've been hearing/saying basically this for decades. After almost 13 years of development Wayland gains a (de-facto not even standardized) way to something as simple as taking screenshots / streaming. This is not "very good".

First of all, this is a standardized way (it is standardized in the XDG desktop portal APIs, which are implemented for example by Plasma and Gnome, and for wlroots-based compositors).

It was also never within the scope of Wayland to provide these kinds of APIs (previously when screen capture was available through the X11 interface, that was more of an accident than an intended feature, and it was an intentional design choice not to repeat this mistake in the design of Wayland).

Instead, compositors and applications (that use the Wayland protocol to communicate) were supposed to agree on a standard interface to do these kinds of things and then use that interface. And that's in fact what they did, by implementing the XDG desktop portal system (that's entirely separate from Wayland). I also see evidence of this interface existing as far back as 2016, although I didn't go digging for when it was initially invented.

Notice that this article doesn't say "is it now possible to screen capture when using Wayland", it only says that OBS Studio now uses this standard interface for screen capturing.

Is it still a competitive advantage if nobody wants X11 anymore, though?

In windows yes, I've never had luck under linux myself.

hm, I've used it using v4l2loopback and while finding the right parameters was a bit fiddly it then worked fine.

yep, can second the needing to fiddle a bit-- i've had some pretty annoying color issues as well, where i fix white balance, etc. in OBS, but the output in Hangouts/etc. looks terrible, like it's ignoring the filtering i'm doing, or there's a pixel format issue or something

Installing a bunch a different repositories for every new version of a software you want is a risky recipe to get a system that will break something on upgrade or that you get barred from upgrade because of some packages or can't upgrade some packages... things like these. On the other hand, even with ubuntu 16.04 (supported until recently) you can easily get the latest version through flatpak.

How does flatpack solve these issues in a way a PPA doesn't?

Project you want needs libA>2, your system provides libA=2. For reasons unrelated to the system itself they can't be installed together as proper packages. PPA may be able to solve it with vendoring, but it's a pain and distro-specific. Flatpak does not have this issue by design.

Thanks, I'll double check the kernel sources in my distro (I'm using Fedora 33).

Totally unrelated but: The day I can wireless screencast my Linux Laptop to my home television I will lite a candle.

wow, thank's for the link! Should be installed by default, it's such a convenient thing and narrows the usability gap of a Linux desktop compared to Windows/MacOS

Maybe a bit off topic but what is the status of wayland capture support anyway? Normally I used ffmpeg with x11 and that worked great. However due to the security model of wayland this doesn't seem nearly as easy to implement. I think they went with some kernel level grabbing support that needed root?

Capturing has been working for a while. The compositor provides a stream over Pipewire.

all right thanks for the info
