One nit pick regarding terminology: In the world of VirtualGL, "host" generally means "server machine", so please use the term "client" or "client machine" to refer to the computer that runs vglconnect/vglclient.
Instructions for setting up TurboVNC on Fedora: - cd /etc/yum.repos.d - sudo wget https://turbovnc.org/pmwiki/uploads/Downloads/TurboVNC.repo - sudo dnf install turbovnc then run /opt/TurboVNC/bin/vncserver to launch a session. Please report any issues you encounter with that procedure on GitHub (https://github.com/turbovnc/turbovnc/issues/new) or the TurboVNC-Users mailing list (https://turbovnc.org/About/MailingLists). As far as the VGL error message, that's a known issue with Fedora's distribution of VirtualGL: https://github.com/VirtualGL/virtualgl/issues/102 Please try installing our official package: - cd /etc/yum.repos.d - sudo wget https://virtualgl.org/pmwiki/uploads/Downloads/VirtualGL.repo - sudo dnf install VirtualGL O/S distributors unfortunately like to distribute the VirtualGL faker libraries in non-default library directories, without understanding that this will break the ability to use VirtualGL with certain types of applications (including VLC and popular web browsers.)
