This is contradictory to what I have experienced with DisplayLink DL-165 based device[1]. *Without engaging multiseat(udev's rule)* picture is garbled on the connected monitor, regardless of whether monitor(DVI) comes with the correct EDID or monitor(VGA)[2] without/broken EDID. EDID loading by /etc/modprobe.d/drm_kms_helper.conf: options drm_kms_helper edid_firmware=edid/848-480[2] doesn't work at all, and even with working kernel boot parameter: drm_kms_helper.edid_firmware=DVI-I-1:edid/848-480[2] system boot stuck few minutes and picture is garbled as before. [drm] Got external EDID base block and 0 extensions from "edid/848-480" for connector "DVI-I-1" [drm] write mode info 153 … And when connected monitor get activated with e.g. xfce4-display-settings(picture is still garbled), then nouveau start spitting messages: nouveau E[ DRM] fail set_domain nouveau E[ DRM] validate gart_list nouveau E[ DRM] validate: -22 nouveau E[ DRM] fail set_domain … with slowing down the system. *With engaging multiseat(udev's rule)*[3] monitor adapter[1] is powered on, but connected monitor(VGA/DVI) stays powered off(NO SYNC). If the system ever reaches gdm. Major Bummer! Stef, what you talkin bout? :) What/where is Hans's patch? Is your multiseat setup on Fedora 18 with udl, or Fedora 17 with udlfb? Cheers, poma p.s.
