Unable to open display or run xterm

I did a chmd on /tmp/.X11-unix and got X "kind of" up.  i.e., I have a 
screen and a cursor and alt tab will move me in and out of Windows XP 
windows/apps.  I can't get an xterm running and when I right click on 
the X icon in the system tray and 'exit' the submenu that comes up says 
that 0 processes are running.  Attempting to launch an xterm from a 
cygwin window with "DISPLAY=127.0.0.1:0.0 && xterm &" fails with a 
message that it couldn't open the display.  I am not sure what the 
parameters in the DISPLAY variable are, however, I have tried using 
LOCAL:0:0 and got the same effect.  This occurs on a Dell Inspiron 8600 
laptop and on a very recent buld HP Pavilion (Sempron processor).  Both 
have the same cygwin packages installed, and I can ssh to my linux boxes 
on them wth no problem (though not from X, of course).
The attached XWin log and config file are from this laptop.

You're not setting DISPLAY correctly.  Try:

DISPLAY=:0 xterm&

The && does not make any sense for what you are trying to do.

Re: Unable to open display or run xterm

Christopher Faylor suggested that I try:
DISPLAY=:0 xterm&
This immediately failed with error 53 (after hitting return twice).  The 
exact same thing occurred in attempting to run xclock (DISPLAY=:0 
xclock&).  I am not sure what error 53 is  (or where it is coming from  
- xterm or the shell  - or). When I close windows (right click on X in 
tray then exit button) I get a message that zero clients are running.  I 
am currently trying this on my HP desktop which has a geForce 7600 
display adapter (i.e., 2 monitor capable adapter).  The X display does 
come up and I can move the cursor with the mouse, so I presume X is 
hitting the correct spigot.

$ net helpmsg 53

The network path was not found.

Sounds to me like other software is getting in your way (anti-virus,
firewall, etc.)

Help with may non-us keyboard (es)

I am working from windows XP with a spanish keyboard. My keyboard 
doesn't work with x apps (well, "space bar" and "return" works but 
nothing else ... ). I've tried to add the "-xkblayout *es*" option when 
executing xwin in the startwin.bat, but nothing changes.

Only if I use "-xkblayout *us*" works (well, I can write but guessing 
where the characters must be in a US keyboard that I don't have ...)

This is part of my xwin.log:

...
...
XFree86-Bigfont extension local-client optimization disabled due to lack 
of shared memory support in the kernel
(--) Setting autorepeat to delay=500, rate=31
(--) winConfigKeyboard - Layout: "0000040A" (0000040a)
(--) Using preset keyboard for "Spanish (Spain, Traditional Sort)" 
(40a), type "4"
(++) XKB: layout: "es"
(--) 3 mouse buttons found
Could not init font path element /usr/X11R6/lib/X11/fonts/CID/, removing

Thanks in advance!

Multiple Session Question

Hello,

I've got cygwin working well via SSH to single host, single window. 
I connect via SSH, and run "startkde" - I get the KDE desktop in one 
single window. Works great!

How do I connect to a second machine at the same time.

See below for details.

-Duane.

For example:
    I login as my self - with ssh & a remote session
And I login as another person to the same machine.
     In my case, I have two accounts:
		A development account
	And	A Test account.

Likewise, I have this situation:
	I login to Machine1 - and it works.
	I login to Machine2 - and it works.

Problem:
	I can only have 1 connection to 1 machine at a time.
	Both should have separate window/display.

I have done this with commercial X11 packages, but not CygwinX.

This does not seem to work, and I can't seem to find in the user docs

Modal windows

We have a MOTIF app that works correctly when displayed on a debian 
sarge (that is, using xfree) or win2k+exceed8.0.

With cygwin-xfree on winxp, however, the modal windows do NOT stay on 
top of the main application window, the main comes up whenever one 
clicks in it.

In all 3 cases, the client libraries are linux/xfree, at exactly the 
same version.

Is that behavior

- by design?

- a known bug?

- due to a user error?

- a bug never reported yet?

TIA,
--

You will need Xwin :1 for the second and Xwin :2 for the third session
and so on.
But i wonder how your first connect works anyway, have you setup ssh
tunneling somewhere?

You will need this

I don't think so.

not needed here

Don't
