Hi Folks,
I'm a bit concerned about Wayland. My signal processing users open multiple remote connections to multiple remote servers and forward their graphical displays to their local machines, many times using multiple virtual desktops on that one local machine.
While X11 was designed with network transparency in mind, that requirement apparently wasn't considered important with Wayland.
In other words, Wayland seems to be a regression to Windows.
Windows window system is not network transparent. Remote Desktop functionality is available for Wayland too.
What will my users have to do to maintain network transparency?
Nobody was using X11 native network transparency for years if not decades. XDMCP is disabled by default for as long as I remember. OK, probably except SSH X11 forwarding but it is suitable for only very simplistic use cases.
I don't think 'Nobody' is an accurate assessment. I will agree that the number of users is perhaps too few to make it a core design feature.
I too am interested in being able to do a remote desktop (not just a specific app) into a Wayland session. I have been using vncviewer to access the primary desktop :0 - I want to share what the user is doing, i.e., the current existing desktop). But with Wayland that only gets me as far as the login. After that, I get a black screen. So if I
Correct. With Wayland you are talking to Wayland compositors. Display manager starts its own compositor to display greeter (kwin, mutter, whatever); when you login, *another* compositor is started as part of the user session. For this to work transparently the connection to the remote viewer needs to be passed from the display manager compositor to the user session compositor. GNOME has implemented it and it should be supported in the recent GNOME (last time I looked Tumbleweed still did not have suitable FreeRDP though, I have not checked since then). KDE still does not support it, I believe someone mentioned this recently on one of the openSUSE lists.
want to access the desktop remotely, I must, in the login screen, select X11. BTW, I'm really glad I can get that far and make that decision! This and Tk are the only reason I still need X11.
Yes, X11 architecture is different, there is X11 server running outside of any user session and both display manager and user session talk to it. So, it is enough to only snoop on this X11 server. Which may have security implications that Wayland tried to address.
All this is on Tumbleweed. Which OBS application works best to access/share an existing remote Wayland desktop (In X parlance :0)?
To start with - a user cannot have multiple GUI sessions using any of the most popular desktops (including different desktops). It is unrelated to X11 vs Wayland.
