To me, all of this makes perfect sense when applied to an installed and running system. However, in the original post, Simon referred to booting a "Fedora Workstation Live USB". AFAIK, the Live image does not contain the xorg-x11-drv-dummy. Additionally, the way the Live image is structured I don't believe there is the chance to make a configuration change to the drivers that are being used. That is why I only suggested the dummy plugs. -- Fedora Users List - The place to go to get others to do the work for you _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
