I wouldn't worry - if he needs to bask he'll be attracted to the spot where the light is brightest.
The main thing really is not to over-fuss him - let him settle, find his way about and get comfortable with his new environment.
That also means not spending too much time lurking up against the glass! It might be putting him off basking if he feels too exposed with this new big human thing so close!
Reptiles are often sensitive to new surroundings, be patient, relax and you'll end up with a nicely tame little guy - just don't try to rush or force it.
