Brilliant. This is another piece of evidence on the pile of why we got Wayland: it's because people who understood X11 mostly retired and everyone else couldn't be bothered to learn X11 because it's "yucky C code" or something. And it bothers me that we lose remote rendering with Wayland (unless one fights with waypipe) that was just built-in to X11. Yes, it was slow, but actually if you're running a VM on your local system and using SSH to connect to it, then it works great. Sigh. I'm an old person yelling at clouds.

This is nonsensical myth-making. Despite the clickbait title, the APIs called in those code samples are very basic and not some forgotten wizardry.

[compiler-devel]

What part is nonsensical? Because Wayland is basically a fulfillment of jwz's CADT.

[sho_hn]

The part where we got Wayland because we lost a magic caste of rockstar engineers who could call XRRGetOutputInfo/XRRGetCrtcInfo.

> Yes, it was slow,

Not particularly if you are on a low latency network. Modern UI toolkits make applications way less responsive that classical X11 applications running across gigabit ethernet.

And even on a fast network the wayland alternative of 'use RDP' is almost unusable.

[kllrnohj]

the approach used in this blog post requires rdp. It's not drawing using X, so there's no vector network transparency.

Nope, this post is using GLX over the network.

[kllrnohj]

Nope, that's indirect rendering and is limited to OpenGL 1.4 more or less. This is using a much newer OpenGL than that.

Also if you look at the source it's specifying direct rendering in glxCreateContext: https://humungus.tedunangst.com/r/xtoys/v/tip/f/circle.c & https://registry.khronos.org/OpenGL-Refpages/gl2.1/xhtml/glX...

The only thing leaving that process is a pixbuf, zero X11, identical to Wayland.

[nullc]

For whatever reason X11 shoving pixbufs over the network seems to have orders of magnitude better performance than actual RDP over a high speed network.

Clients can draw locally and composite remotely. I do not see the issue.

[kllrnohj]

draw locally composite remotely is literally Wayland's philosophy and is one of the biggest contentious issues for the pro-X11 crowd.

This what Wayland copied from modern X clients.
