  We present Chandra detections of x-ray emission from the AGN in two giant Low
Surface Brightness (LSB) galaxies, UGC 2936 and UGC 1455. Their x-ray
luminosities are 1.8\times10^{42} ergs/s and 1.1\times10^{40} ergs/s
respectively. Of the two galaxies, UGC 2936 is radio loud. Together with
another LSB galaxy UGC 6614 (XMM archival data) both appear to lie above the
X-ray-Radio fundamental plane and their AGN have black hole masses that are low
compared to similar galaxies lying on the correlation. However, the bulges in
these galaxies are well developed and we detect diffuse x-ray emission from
four of the eight galaxies in our sample. Our results suggest that the bulges
of giant LSB galaxies evolve independently of their halo dominated disks which
are low in star formation and disk dynamics. The centers follow an evolutionary
path similar to that of bulge dominated normal galaxies on the Hubble Sequence
but the LSB disks remain unevolved. Thus the bulge and disk evolution are
decoupled and so whatever star formation processes produced the bulges did not
affect the disks.
