에서 x11vnc 로 설정하는 부분이 있다.
아래부분처럼 설정하면, shift key 가 안 먹힐것이다.
다음처럼 바꿔주면 된다.
-xkb 옵션을 넣으면 shift key 가 먹힐 것이다. 그리고, -repeat 옵션도 추가되었는데.
키보드의 키를 누르고 있으면 반복입력되는데, 기본옵션이 -norepeat 라서 반복입력이 되지 않는다.
*** x11vnc was unable to open the X DISPLAY: ":0", it cannot continue.
*** There may be "Xlib:" error messages above with details about the failure.
Some tips and guidelines:
** An X server (the one you wish to view) must be running before x11vnc is
started: x11vnc does not start the X server. (however, see the -create
option if that is what you really want).
** You must use -display <disp>, -OR- set and export your $DISPLAY
environment variable to refer to the display of the desired X server.
- Usually the display is simply ":0" (in fact x11vnc uses this if you forget
to specify it), but in some multi-user situations it could be ":1", ":2",
or even ":137". Ask your administrator or a guru if you are having
difficulty determining what your X DISPLAY is.
** Next, you need to have sufficient permissions (Xauthority)
to connect to the X DISPLAY. Here are some Tips:
- Often, you just need to run x11vnc as the user logged into the X session.
So make sure to be that user when you type x11vnc.
- Being root is usually not enough because the incorrect MIT-MAGIC-COOKIE
file may be accessed. The cookie file contains the secret key that
allows x11vnc to connect to the desired X DISPLAY.
- You can explicitly indicate which MIT-MAGIC-COOKIE file should be used
by the -auth option, e.g.:
x11vnc -auth /home/someuser/.Xauthority -display :0
x11vnc -auth /tmp/.gdmzndVlR -display :0
you must have read permission for the auth file.
See also '-auth guess' and '-findauth' discussed below.
** If NO ONE is logged into an X session yet, but there is a greeter login
program like "gdm", "kdm", "xdm", or "dtlogin" running, you will need
to find and use the raw display manager MIT-MAGIC-COOKIE file.
Some examples for various display managers:
gdm: -auth /var/gdm/:0.Xauth
kdm: -auth /var/lib/kdm/A:0-crWk72
xdm: -auth /var/lib/xdm/authdir/authfiles/A:0-XQvaJk
dtlogin: -auth /var/dt/A:0-UgaaXa
Sometimes the command "ps wwwwaux | grep auth" can reveal the file location.
Starting with x11vnc 0.9.9 you can have it try to guess by using:
(see also the x11vnc -findauth option.)
Only root will have read permission for the file, and so x11vnc must be run
as root (or copy it). The random characters in the filenames will of course
change and the directory the cookie file resides in is system dependent.

vnc 를 띄울 적절한 X display 를 찾지 못했다. 접속할 권한? 대략 그런의미.(정확한 이해를 아직 ...)
윈도우매니저 별로 차이가 있다. gdm , kdm , ubuntu 11.04 부터인가 바뀐 unity 도 좀 다르다.
-auth /var/lib/gdm/:0.Xauth 부분이 안되는 경우이다.
