Nvidia drivers -> no 32 bit depth?

Vgui · 08-09-2005, 06:10 PM

I just upgraded to the 7667 line of drivers on an Nvidia card. But when I try to set the color depth to 32 (in xorg.conf) and reboot X, it says that "is not supported". The highest I can go is 24. I've heard that 24 is basically the same thing, so I'm just wondering for interest sakes why it would say this?

Just a shot in the dark, but do you have the right monitor set in xorg.conf?

I *think* they have just choosen to relable it in a more sane manner. "24 bit color" means you have 2^24 colors (aka 16,777,216 colors). "32 bit color", however does not mean you have 2^32 colors (aka 4,294,967,296). You still have 16.7 million colors.... you just get an 8-bit buffer to go with it. The nVidia driver calls the color depth correctly, and rest assured, it also provides the buffer.

Hi,
I just check my xorg.conf, and everything is setup correctly there. I wasn't too worried about whether it was truly enabled or not, I was just wondering why it was saying I couldn't do it. I'm gonna fool around with it a bit more (maybe trying different resolutions / refresh rates) and I'll see what I come up with.

Just thought I'd add the actual error message *shrugs*

Code:

(EE) NVIDIA(0): Given color depth (32) is not supported
(EE) NVIDIA(0):  *** Aborting ***
(EE) Screen(s) found, but none have a usable configuration.
