How to setup easy switching?

[Gaccm]

I want to have two diff X enviorns.
1) KDE running in 32bit
2) Blackbox running in 16bit

i cant figure out any easy way to switching between them. what i would like is to just have two diff aliased commands, like 'kde' and 'bbox' which each starts its own X environs.
Has anyone done this successfully?

I've considered doing something very close to this .. one configuration that starts my normal xsession (Enlightenment with a Gnome panel) and one for gaming (X with nothing but an Xterm). I haven't tried it yet, but what i was thinking of doing is this:
1. Make two text files which can be cp'd to .xinitrc with the relevant enties to startx with my desired configuration.
2. Create 2 simple bash scripts that copy said text files to .xinitrc and startx.

The bash scripts, I assume could simply contain:
#!/bin/bash
cp game.txt .xinitrc &&
startx

or

#!/bin/bash
cp desktop.txt .xinitrc &&
startx

in your case you could use

#!/bin/bash
cp blackbox.txt .xinitrc &&
startx -16bpp

and

#!/bin/bash
cp kde.txt .xinitrc &&
startx -32bpp

Then you could invoke x by calling the script files which should startx with the correct window manager and color depth. Of course I have yet to try this, but in theory it should work.

dang, i was trying to figure out this complex aliasing the commands without having to use the .xinitrc, and you come and blow it all away with two simple 2 line scripts :)
Why do you have the && in the cp command? what is its purpose, but other than that it seems 100% to my eyes.

another slight change
its not startx --16bpp
its startx -- -depth 16 (well, for 4.x)
also, X doesn't technicly 'have' 32bit, i dont really understand it. If you try to startx with 32 depth it errors with 'no screen found'

Yup, its actually 24bit color with an 8bit frame buffer which gives you 32bit color. So I guess it would be startx -- -depth 24.
The && is to make sure the startx isn't run until the txt file is copied to .xinitrc. May not be neccessary, just being safe :)
