> xpra initialization error: > xpra_Xdummy: did not provide a display number using displayfd Based on this message, I'm not convinced that you are actually using xvfb. Double-check your configuration with: xpra showconfig | grep -i ^xvfb > I do not think Xvfb is installed on this system, even though Xorg is. The xorg-x11-server-Xvfb package on CentOS / RHEL 7.x only contains one binary file named "Xvfb". You can just unpack the RPM by hand and put the binary in your $PATH. The dependencies should already be present if you have /usr/bin/Xorg installed. > As > an unprivileged user it may be hard for me to install Xvfb, so could > there be a different solution? Yes, figure out why you get those tty errors when running xpra_Xdummy. Regular CentOS 7.x systems can normally run it just fine.
