Created attachment 324391 journal of F24 alpha6 in Boxes (guest)

Host: virt-manager-1.3.2-1.fc23.noarch libvirt-daemon-1.2.18.2-2.fc23.x86_64 gnome-boxes-3.18.1-1.fc23.x86_64

Problem happens in Boxes with Fedora-Workstation-Live-x86_64-24_Alpha-6.iso but does not happen with Alpha 5. Nor does it happen with either Alpha 5 or Alpha 6 in virt-manager.

At flickering gdm screen, I keep getting a lot of these entries: Mar 20 16:03:57 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output Mar 20 16:03:58 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output Mar 20 16:03:59 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output Mar 20 16:04:00 localhost.localdomain kernel: qxl 0000:00:02.0: ffff88007a3d0800 unpin not necessary Mar 20 16:04:00 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output Mar 20 16:04:01 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output Mar 20 16:04:02 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output Mar 20 16:04:03 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output Mar 20 16:04:04 localhost.localdomain gnome-settings-daemon.desktop[1560]: (gnome-settings-daemon:1560): color-plugin-WARNING **: unable to get EDID for xrandr-Virtual23: unable to get EDID for output

Once logging in, there are a lot of messages so I'll just include the entire journal for this boot as an attachment.
