You could increase the rank of the matrix space?
sage: M = MatrixSpace(QQ, 20)
sage: L.<x> = PolynomialRing(M)
sage: 1-x
prints a lot nicer. It illustrates that printing matrices, let alone
printing polynomials with matrix coefficients, very quickly becomes
problematic.
For simply cases, you could do some ad-hoc things like:
repr(1-x).replace("]\n[","; ")
which at least puts the matrices in a line-format. If you're working in the
notebook, show(1-x) might do a reasonable job in producing readable 2d
output (on small examples)
