xserver
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
That I know how to do when it's what I want to do. :-)
All of the X servers accept the command line options
described
below. 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 by
default 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.
'man Xorg' works here.
I think you are trying to teach me how to do what I already know how to do,
which has nothing to do with the purpose of the exercise.
And I have full featured man page for tdecmshell
On openSUSE, or on a Debian? (sidetracking....)
# 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.
Not exactly. Correct WRT :0. It has no effect on any program already open on :0,
which is one half of the point of the exercise. The xrandr DPI change only
affects programs opened after running it. I want before and after screenshots,
purely for the purpose of showing someone what does and does not change as a
result of a DPI configuration change. I succeeded in the bulk of reaching my
goal, but inelegantly by using xterms instead of before and after tdecmshells I
was expecting to be able to utilize. With tdecmshell I was expecting its own UI
to demonstrate non-text effects on UI sizing, but most important was the text
impact.
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
Clearly. :-)
- 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've been using multiple "screens" on the same display (:0, :1 and/or :2 running
"simultaneously") forcing resolutions and DPIs for roughly a decade (mostly on
test installations, rarely on my 24/7 systems). I only do it one of two ways
though, never according to the man excerpt above, and never (except very
occasionally very temporarily) via a dpi setting squirreled away in some DE's
config file, and very very rarely using Xft.dpi (see: [2]). Either I run xrandr
in a startup script[1], or via DisplaySize and/or PreferredMode in
/etc/X11/xorg.conf*.
