In your example I don't see how you are passing the display number to xserver command
I've not been, and adding it doesn't change anything. I'm not trying to start a server. I'm trying to alter the already running server from within the running server. The commands are all run on screen :0 in the instant case. Why does the first instance work as expected (as it has since it was KDE3 and probably KDE2 before) without specifying a screen?
I was thinking you want to run xserver on different port/screen
All of the X servers accept the command line options describedbelow. Some X servers may have alternative ways of providing the parameters described here, but the values provided via the command line options should override values specified via other mechanisms.
:displaynumber The X server runs as the given displaynumber, which bydefault is 0. If multiple X servers are to run simultaneously on a host, each must have a unique display number. See the DISPLAY NAMES section of the X(7) manual page to learn how to specify which display number clients should try to use.
# man X(7) bash: syntax error near unexpected token '('. # man X no manual entry for X
Strange I have man for Xorg and for X - perhaps you are missing something. And I have full featured man page for tdecmshell
# tdecmshell --help-all only shows a displayname option, no displaynumber # tdecmshell --help-all Usage: kcmshell [Qt-options] [KDE-options] [options] module...
Says nothing about server options.
Qt options: --display <displayname> Use the X-server display 'displayname'
What is shown in http://fm.no-ip.com/SS/dpi108vs133.jpg is all from a single running instance of starttde, not some cut and paste hocus pocus.

What you show on the image means you change the DPI on display :0 (default) and it will impact all programs run there.
I haven't spent too much time with X, but also not too less. AFAIR it was 1.GPU -> 1.Screen -> 1..n Display(s)
In general I do not understand what you want to achieve - you can not run a Xserver from within Xserver and let it bind to the same screen port which is already taken by the first Xserver running. In my opinion you can run xserver on :1 or :2 from the native console (but it would require more work to run applications there ... see session management)
man xserver ... -dpi resolution sets the resolution for all screens, in dots per inch. To be used when the server cannot determine the screen size(s) from the hard‐ ware.
At least AFAIR this is what vnc is doing, where (AFAIR) you specify the port example :5 and then can connect from remote to xserver on :5 remote via vnc.

I hope this helps
