  We present both coronal and chromospheric observations of large-scale
disturbances associated with a major solar eruption on 2005 September 7. In
GOES/SXI, arclike coronal brightenings are recorded propagating in the southern
hemisphere. The SXI front shows an initially constant speed of 730 km s$^{-1}$
and decelerates later on, and its center is near the central position angle of
the associated coronal mass ejection (CME) but away from flare site.
Chromospheric signatures of the disturbances are observed in both MLSO/PICS
H$\alpha$ and MLSO/CHIP He I 10830 {\AA}, and can be divided into two parts.
The southern signatures occur in regions where the SXI front sweeps over, with
the H$\alpha$ bright front coincident with the SXI front while the He I dark
front lagging the SXI front but showing a similar kinematics. Ahead of the path
of the southern signatures, oscillations of a filament are observed. The
northern signatures occur near the equator, with the H$\alpha$ and He I fronts
coincident with each other. They first propagate westward, and then deflect to
the north at the boundary of an equatorial coronal hole (CH). Based on these
observational facts, we suggest that the global disturbances are associated
with the CME lift-off, and show a hybrid nature: a mainly non-wave CME flank
nature for the SXI signatures and the corresponding southern chromospheric
signatures, and a shocked fast-mode coronal magnetohydrodynamics (MHD) wave
nature for the northern chromospheric signatures.
