I am handling user issues in my team. Users have their Unix session running on Citrix MFU.
Recently, I was suppose to address a user issue which is as below:
Gets the below error when tries to open nedit:
Code:
Xlib: connection to ":165.0" refused by server
Xlib: Client is not authorized to connect to Server
NEdit: Can't open display
Gets the below error after running ssh -X <hostname>
Code:
Xlib: connection to "localhost:173.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
NEdit: Can't open display
echo $DISPLAY gives :165.0 as output.
I tried with below things. Still negative results
- Reset the user's .Xauthority file and reconnected to the session.
- xhost +hostname
- nedit -display :165.0
As per user, if he logs out and starts a fresh session he is able to launch nedit and gvim without any errors.But the errors again repeat after few days.
Please advice or suggest any resolution for these errors or Please let me know actions to take when a user reports about Xlib errors.

Hi all,
I'm currently learning xlib and I've encountered a bizarre mistake: function calls such as XDrawPoint, XDrawLine, etc., don't seem to work; a blank window with nothing in is appears. I believe this has something to do with the window manager I use, fluxbox.
After checking the code and... (0 Replies)

Hello. I used to have Pango compiled, however it did not have X support, only Freetype support. Since gtk requires pangoX to be compiled, I went to compile it with Xsupport.

XHPSetErrorHandler(3X)XHPSetErrorHandler(3X)NAME
XHPSetErrorHandler - Register an X error handling routine.
SYNOPSIS
#include <X11/XHPlib.h>
typedef int (*PFI) ();
PFI XHPSetErrorHandler (display, routine)
Display *display;
int (*routine) ();
int routine (display, error)
Display *display;
XErrorEvent *error;
DESCRIPTION
This request registers with Xlib the address of a routine to handle X errors. It is intended to be used by libraries and drivers that wish
to establish an error handling routine without interfering with any error handling routine that may have been established by the client
program.
XHPSetErrorHandler records one error handling routine per connection to the server. Therefore, in order for a library or driver to set up
its own error handling routine without affecting that of the client, the library or driver must first have established its own connection
to the server via XOpenDisplay.
When an XErrorEvent is received by the client, which error handling routine is invoked is determined by the display associated with the
error. If the display matches that associated with a driver error handling routine, that error handling routine will be invoked. If it
does not match any driver routine, the error handling routine established by the client, if any exists, will be invoked. Otherwise, the
default Xlib error handler will be invoked.
XHPSetErrorHandler returns the address of the previously established error handler. If that error handler was the default error handler,
NULL is returned.
A driver or library may remove its error handler by invoking XHPSetErrorHandler with a NULL error handling routine.
