  We use event driven simulations to analyze glassy dynamics as a function of
density and energy dissipation in a two-dimensional bidisperse granular fluid
under stationary conditions. Clear signatures of a glass transition are
identified, such as an increase of relaxation times over several orders of
magnitude. As the inelasticity is increased, the glass transition is shifted to
higher densities and the precursors of the transition become less and less
pronounced -- in agreement with a recent mode-coupling theory. We analyze the
long-time tails of the velocity autocorrelation and discuss its consequences
for the nonexistence of the diffusion constant in two dimensions.
