Are you using wayland on the desktop? https://blogs.s-osg.org/wow- wayland-over-wire/ explains difficulties. The wayland FAQ discusses a number of possibilities for networking GUI apps under wayland. Running a VNC server on the desktop seems like the least experimental option. I use it on SL7, which uses a similar systemd setup where a VNC server is started for each VNC user: https://docs.fedoraproject.org/en-US/Fedora/25/html/System_Administrators_Guide/ch-TigerVNC.html > _______________________________________________ > users mailing list -- users@lists.fedoraproject.org > To unsubscribe send an email to users-le...@lists.fedoraproject.org > -- George N.
