Um, maybe I'm ust blind or something, but I don't see an option to change my color depth anywhere in my system settings. I'm using a Toshiba satellite laptop with a nVidia Gforce4 420 Go, which already required me to change a bunch of stuff in my xorg.conf to get it to work. Here is part of my xorg.conf. Even though it says the default is 16, my monitor doesn't look 16, it looks 32.
