Gnome-shell core dump on fedora 31 and XDMCP


I’m trying to setup XDMCP on fedora 31. I feel I’m pretty close but I now get a white screen with an “unrecoverable error” message

My journalctl output contains the following:

gnome-shell[1662]: No XInput 2.3 support

gnome-session-binary[1601]: Unrecoverable failure in required component org.gnome.Shell.desktop

Process 1662 (gnome-shell) of user 42 dumped core.

I’m using Xming from a Windows 10 machine to connect.

Anybody seen this before?

This is a required X extension.

Are you trying to run GNOME Shell on an X server on Windows, or are you running the X server on a Linux machine and trying to connect to it via forwarding?

Hi @ebassi thanks for your quick reply.

I’m trying to run a Gnome shell on an x server on windows.

It’s highly unlikely it’ll work. AFAIR, most X servers available for Windows are ridiculously out of date when it comes to required extensions needed for any modern use of X—especially for a complex compositor like GNOME Shell.

Pity. I wanted to get this to work for a long time already. I tried a couple of x servers. None of them seem to work so I’m afraid you’re right. Thanks anyway.
