7600 GS & 32 Bit Depth

[drs305]

I recently started noticing 32 bit depth advisories when opening certain apps. They could have always been there and I didn't notice, the drivers may have changed capabilities, or perhaps newer apps are asking for 32 bit depth that didn't previously.

One of the first places I noticed it was when opening VirtualBox, which said I should run in 32 bit depth if possible. I don't remember seeing that when I first started using VBox.

I have an nvidia GeForce 7600 GS running the nvidia 180-44 driver from the ubuntu packages.

I tried manually changing 24 to 32 in xorg but that didn't work and I couldn't get a 32 bit option when trying to change it via nvidia-settings and nvidia-xconfig.

Can this card just not run higher than a depth of 24 on ubuntu?

Thanks for any inputs.

This is an update to the original post. I've done even more searching.

I found information indicating nvidia in linux designates 24 bit and won't use "32 bit" since this is a "more honest" representation of the true abilities of color representation - even though it has essentially 32 bit depth abilities.

So my real question becomes, if I can't get xorg and nvidia to designate 32 bit depth, how can I run apps that require 32 bit depth and give me errors when I try to run them. A bit less problematic is that VirtualBox also gives me messages saying that I should be running 32 bit depth (of course, I can elect to remove the notification should I choose).
