How to connect to vnc server?

Question

Gnome

Given: Fedora 21, Tiger-vns, GNOME Shell 3.14.3 Everything
was done according to the dock: HERE .
When connecting from the client to the server, the message "Oh no! Something has gone wrong" appears.
xstartup config:

#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
#xsetroot -solid grey
#vncconfig -iconic &
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
  eval `dbus-launch --sh-syntax –exit-with-session`
  echo "D-BUS per-session daemon address is: \
  $DBUS_SESSION_BUS_ADDRESS"
fi
exec  gnome-session

They write about the bug and write about all sorts of solutions. - recipes did not help *(
Maybe one of the bakers encountered such a problem?
Or tell me how else you can connect to the working environment?

Answer 1

Debug without a daemon.
If you manually run "sudo -u des -H vncserver" does it start listening on a port?
Checked with "netstat -ntlp | grep vnc" command.
After that, can you connect to it?
If so, there is a bug in the systemd settings.
If not, there is an error in xstartup.
Before each command and at the end, put calls to logger to see if execution reaches them.
