Q: Default bpp resolution 32 in Linux?

["Jonathan Gift" <jgift@wanadoo.fr>]

Hi,

While I realise you can have many different color depths, I remember reading
(but am not sure) that 32bpp is the Linux default... assuing the card
supports it.

I just want to check if that's so and what difference that makes with 24
bit, sice the number of colors is the same?

Thaks,

Jonathan
