I am trying to enlarge the ticks labels using the TicksStyle property without any success. This property does not affect neither font face nor size (i tried wide variety of options).
Actually, my trouble is best illustrated by screenshot

I have no clue what is the reason of such behavior; may be it is in my system (according to Mathematica About screen i am using Mathematica 10.0.1.0 on Linux x86 (64-bit) if this matters).
