waiting for X server to begin accepting connections .

waiting for X server to begin accepting connections .

[Marc Girod]

Hello,

Tonight, from home, over my employer's VPN connection: impossible to start
Gnu emacs over X.
After the usual expr dumping core:

/usr/bin/startx: line 47:  6444 Segmentation fault      (core dumped) expr
"$1" : ':[0-9][0-9]*$' > /dev/null 2>&1

I get an effect which I have already seen, but only until now in a transient
mode:

waiting for X server to begin accepting connections .
..
..
..
..

Only now, it goes on until timeout, and reproduces on the next try...

The log ends in:

xwin> tail -2 XWin.0.log
[ 12500.250] winMultiWindowXMsgProc - XOpenDisplay () returned and
successfully opened the display.
[ 12500.250] winClipboardProc - XOpenDisplay () returned and successfully
opened the display.

My command (in a batch file):

chdir C:\cygwin\bin
bash --login -c "/usr/bin/startx /usr/bin/emacs -g 90x37+150+0 -- /usr/bin/X
:0 -multiwindow -clipboard"

What can be the cause?
Thanks
Marc

I started looking at the .server* and .Xauthority files.
Found that .Xauthority keeps growing (but not since the origin of times--and
see below: cleaned up after timeout!).
Now, I removed a previous version so that I only have a smaller chunk left:

~> strings .Xauthority
EV68B599EABE1A
MIT-MAGIC-COOKIE-1
Tnj#
MIT-MAGIC-COOKIE-1
MIT-MAGIC-COOKIE-1
MIT-MAGIC-COOKIE-1
MIT-MAGIC-COOKIE-1
MIT-MAGIC-COOKIE-1
~> strings .serverauth.5268
EV68B599EABE1A
MIT-MAGIC-COOKIE-1
~> wc .Xauthority
  0   3 340 .Xauthority
~> tail -3 /var/log/xwin/XWin.0.log
[  4303.693] winInitMultiWindowWM - XOpenDisplay () returned and
successfully opened the display.
[  4303.693] winMultiWindowXMsgProc - XOpenDisplay () returned and
successfully opened the display.
[  4303.693] winClipboardProc - XOpenDisplay () returned and successfully
opened the display.

It looks like the .serverauth file was cleaned up after the last exit--this
surprises me as I use to find afterwards.
.Xauthority was also cleaned up to a minimal state:

~> od -x .Xauthority
0000000

I'm assuming that this is spam and so am blocking this account from further
communications here.  If I'm wrong the OP should send email to postmaster
to be unblocked and explain the reason for this bizarre question.

Checked that no firewall blocks port 6000 (it should be what the X server
listens to for display :0, right?)

It started to work again...!?
I had just disabled (not the first time, although first with a batch file,
in the right order) the Symantec AntiVirus (both "smcservice" and "Symantec
AntiVirus"), and tried.
Now it works also with Symantec reenabled...

I know I should buy a computer, but this is what I got as working
environment.
The problem pops up for some time (hours...?) every now and then, and
disappears.
Rebooting doesn't help systematically; i.e. it may help, who knows, but not
every time, at least.

Is there any guidance about how to investigate this?
Obviously, the X server is up and running, only the client cannot connect to
it.
Some small test client which would be easy to debug, and might report the
cause of failure?
Here is the bottom of the XWin.0.log:

...
[  1312.467] winMultiWindowXMsgProc - DISPLAY=:0.0
[  1312.467] winClipboardProc - DISPLAY=:0.0
[  1312.467] winInitMultiWindowWM - XOpenDisplay () returned and
successfully opened the display.
[  1312.467] winMultiWindowXMsgProc - XOpenDisplay () returned and
successfully opened the display.
[  1312.483] winClipboardProc - XOpenDisplay () returned and successfully
opened the display.

Thanks,
Marc

Also, choosing a different display (i.e. :1 instead of :0 in my startup
command) works.
So... is this enough to conclude that the issue is bound to the port (some
other unknown application holding it for hours/days and then releasing it)?
