I think you have a diatom problem, not cyanobacteria.  After I increased the
lighting on my community tank, I started getting a brown sludge on the walls
of the tank.  It only shows up if I haven't been doing water changes often
enough (when growth slows down, presumably because of a lack of trace
elements), so a good wipe-down and a water change always clears it up.  If I
don't do a good enough job of wiping the tank, though, they will continue to
spread right where the streaks were left.  I've stopped this by adding
otocinclus (a half dozen in a 75 gallon tank).  My flying fox also seems to
eat it.

There's usually some green algae on the walls, mixed in with it.  So
greenbrownish sounds about right.
