Saturation and geometrical scaling (GS) of gluon distributions are a
consequence of the non-linear evolution equations of QCD. We argue that in pp
GS holds for the inelastic cross-section rather than for the multiplicity
distributions. We also discuss possible fluctuations of the proton saturation
scale in pA collisions at the LHC.Comment: 6 pages, 4 figures, talk presented at Excited QCD, Costa da Caparica,
