I don't know what it's on now but I don't think it defaults to 32 so how do I change it? Thanks.

Ummm... Why? I need to change it to 32 bit, not read a wikipedia article on colour depth. WTF did you even post that for?

It may depend on your hardware and how it's supported...

Try looking at system>preferences>display

My desktop has a Nvidia card which has a lot more options than the Intel chip-set on the laptop which doesn't offer color depth settings.

Yeah I'm sorry. I guess that your too smart for such a simple explanation

here's the basic xfree86.org spec's, maybe have a go a changing them

http://www.xfree86.org/4.3.0/XF86Config.5.html#sect11

note that 3X8 = 24 actual bits used

if you have an actual use for the alpha channel then then i'm sure your more than capable of figuring a solution (vs. 8 padded bits

Dude all I need to know is how to edit xorg.conf. Never had much luck with this website...

sudo nano /etc/X11/xorg.conf
Now you can edit it. Just be careful.

When I open the display properties dialogue, it has little drop down menus to change screen resolution and depth, but it won't let me use them. It says I have to change my configuration file or something like that.

Unfortunately, I can't change and save the configuration file....

My question is why they bothered making a nice menu to edit the properties, but force you to edit it via the terminal anyway. Confused.

The instruction is shown in nano's lower part.

^O = [ctrl]+[o] = save
^X = [ctrl]+[x] = exit
etc.

nano is a cli (commandline interface) text editor. If you sudden messing up the xorg, you can edit/fix xorg from CLI.
