Well, you can set the default color depth in XF86Config as someone
else mentioned. As for running certain apps at different resolutions,
I don't believe that's possible; however, it is possible to run two X
servers at once (on different virtual consoles), each with a different
number of bits per pixel. (you can then switch between the two with
Ctrl-Alt-F?, where ? is usually 7 or 8)
If you're using startx, and start up one server with:
startx -- -bpp 16 # Or just with "startx" if you've made 16bpp default
You can start up another with:
startx -- :1 -bpp 8
Then, the 16bpp server will start on (probably) VT7, and the 8bpp one
will then start on VT8. One thing to watch is that you need to run
startx from a text console, not an xterm. (Unless in /etc/X11/Xserver
you've said that anybody can start up X).
If you use xdm, you can change the last few lines of /etc/X11/Xservers
to be:
:0 local /usr/X11R6/bin/X -bpp 16 vt07
:1 local /usr/X11R6/bin/X -bpp 8 vt08
In xdm you need to specify explicitly the virtual terminal the server
starts on because xdm will start both servers at once, and they'll end
up fighting over the first available terminal.
Once you've started both servers, you can switch from one to the other
as easily as you can change text consoles. Not quite what you
wanted, but workable.
