I am experiencing the same issue, using a Thinkpad W520, on 16.04.
Two external monitors are connected via DVI.
On boot, all three monitors are mirrored, and correctly show the Ubuntu log.
After logging in, I get the same error messages:

The selected configuration for displays could not be applied
could not set the configuration for CRTC 64

and

GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gsd_2drr_2derror_2dquark.Code2: could not set the configuration for CRTC 64

One of the monitors is disabled. If I enable it using the Unity Settings app, the same error message show up. Tailing -f /var/log/Xorg.0.log while enabling the monitor reveals:

[ 451.532] (II) intel(0): resizing framebuffer to 5440x1672
[ 451.582] Cannot do multiple crtcs without X server dirty tracking 2 interface
[ 451.582] randr: failed to set shadow slave pixmap
[ 451.582] (EE) NOUVEAU(G0): failed to set mode: No space left on device

This appears to be the same bug as #1597437. It also seems to have been resolved in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1307204.
