So could you please file a bug report at: http://bugzilla.redhat.com/ What should be included: * make and model of your monitors * /var/log/dmesg after booting with the following kernel parameter: drm.debug=15 * /var/log/Xorg.0.log of the same attempt. Both logs should be attached as text/plain files. Then, please try booting with the nomodeset kernel parameter, and use either xrandr or xorg.conf to configure your dual screen. If that works, please add that to your bug report and include relevant logs (mainly Xorg.0.log) of that attempt.
