How set color depth to 32 in Gnome?

Just installed 32 bit Lenny 5 in virtual box, a software computer, and virtualbox say that it wants the color depth changed from 24 to 32. Tried manually changing xorg.conf but then X would not start saying: 32 depth was inconsistent with 000 weight. No idea what that means.

Thanks any help.

32-bit color

"32-bit color" is generally a misnomer in regard to display color depth. While actual 32-bit color at ten to eleven bits per channel produces over 4.2 billion distinct colors, the term “32-bit color” is most often a misuse referring to 24-bit color images with an additional eight bits of non-color data (I.E.: alpha, Z or bump data), or sometimes even to plain 24-bit data.

Systems using more than 24 bits in a 32-bit pixel for actual color data exist, but most of them opt for a 30-bit implementation with two bits of padding so that they can have an even 10 bits of color for each channel, similar to many HiColor systems.

With Nvidia ,they have --depth=30 option which is for QUADRO cards.
But,You can add "DefaultFbBPP 32" after the line "DefaultDepth 24"

Huge thanks. Can't say I understand any of this but the VirtualBox error message has gone after putting your thing into /etc/X11/xorg.conf. But typo in your above:

Code:

Section "Screen"

        DefaultDepth 24

        DefaultFbBpp 32

EndSection

It's not BPP, it's Bpp.

So great thanks; you are beautiful.:)
