May 2022: It turned out that my assumption that 22.04 LTS would work the same as 21.10 was wrong. So I got the latest image of that release and continued there. So I assume for now that in whatever way the current problem will be fixed before 22.04 is released, the result will pretty much look like what is currently built into Ubuntu 21.10. To my surprise, the functionality is totally broken in my daily build, but I’m not the first to notice. However, there are daily builds available, so I download the latest one to have a closer look at the built-in desktop sharing. It’s still early April 2022 so Ubuntu LTS 22.04 has not yet been released. The answer was not as bad as I thought, but also not as good as I hoped. X11 is still supported, but once Wayland becomes the default, I wonder how much love x11 will still get!? So long story short, I was wondering what kind of remote desktop sharing solution Gnome and Ubuntu are proposing for 22.04 and whether it works as well as x11vnc. But now, it looks like Ubuntu will make Wayland the default compositor in the upcoming 22.04 Long Term Support (LTS) version. One of the problems that have plagued all attempts so far was the lack of a usable remote desktop solution. That’s a bit of a problem these days, as all Linux distributions that use the Gnome desktop, including Ubuntu, are trying very hard for years now to switch to the newer Wayland display server. As the name implies, x11vnc is based on the x11 display server. And if nothing happens on the desktop, there is almost no data transmitted. There are many VNC servers, but x11vnc is the best I have found so far, as it works well even under extremely severe bandwidth constraints, i.e., it can easily live with 1 Mbit/s in the uplink when using the highest compression scheme. For almost 10 years now, I’m using x11vnc to get GUI access on remote Ubuntu desktops. Desktop sharing is one of the essential things I do every day.
