There is no graphical console: the machine is accessible only via ssh. I can reproduce the problem when killing all my processes with "kill -TERM -1", relogging via ssh, and starting evince. Note: I can see that the following processes are created just after evince is started (but still waiting for its window): xdg-desktop-portal, xdg-document-portal, xdg-permission-store. > If you're expecting graphical applications to work "when I connect by > ssh", then presumably you're doing *something* that you're not saying, > either X11-over-ssh forwarding or a separate X11 session or a separate > Wayland session - otherwise these applications would have nowhere to > display their windows.

But /etc/X11/Xsession.d/20dbus_xdg-runtime isn't run via ssh, AFAIK. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
