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:
Gets the below error after running ssh -X <hostname> 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)
1. If there's some better place where xlib experts hang out, please tell me. Despite an assiduous search, I could not find an xlib reflector.

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.
I had to issue a ./configure --prefix=/media/34GB/Arquivos-de-Programas-Linux/PangoX-1.8.2/... (1 Reply)

LEARN ABOUT X11R4
xseteventqueueowner
XSetEventQueueOwner(3) XLIB FUNCTIONS XSetEventQueueOwner(3)NAME
XSetEventQueueOwner - set event queue owner on a shared Xlib/XCB connection
SYNTAX
#include <X11/Xlib-xcb.h>
void XSetEventQueueOwner(Display *dpy, enum XEventQueueOwner owner);
ARGUMENTS
dpy Specifies the connection to the X server.
owner Specifies the event queue ownership:
XlibOwnsEventQueue (default)
Xlib owns the event queue. Use the Xlib event-handling functions. Do not call the XCB event-handling functions.
XCBOwnsEventQueue
XCB owns the event queue. Use the XCB event-handling functions. Do not call the Xlib event-handling functions.
DESCRIPTION
While a client using Xlib/XCB can issue requests and handle their replies or errors with either Xlib or XCB, only one can own and handle
the event queue. By default, Xlib must own the event queue, for compatibility with legacy Xlib clients. Clients can call XSetEventQueue-
Owner immediately after XOpenDisplay to let XCB own the event queue instead. Clients may not call XSetEventQueueOwner at any other time,
as this will potentially lose responses.
