The first answer on this page tells how to fake an attached monitor on linux using the dummy driver. On Fedora that is package xorg-x11-drv-dummy-0.3.7-1.fc25.x86_64 It involves creating a dummy xorg.conf with the parameters you want, since there is no edid to read from the monitor to automatically create it. It's for Ubuntu, but should work fine on Fedora. http://askubuntu.com/questions/453109/add-fake-display-when-no-monitor-is-plugged-in There seem to be problems with it if an actual monitor is attached in addition to the dummy, but that should not be a problem for you. If necessary, though not stated there, it should be possible to create a second configuration for the attached monitor, and then specify which screen you want to load at X startup (it defaults to screen 0). _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org
