nVidia Color Depth

[karmila]

Why in ubuntu my graphic card, nVidia GeForce 6100 nForce 405, can only display 24 bit color depth whilst in windows it can display 32 bit color depth.

Maybe somebody know why?

"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."

In short: 24 bit color depth is what windows calls 32 bit.
