Ubuntu 14.04上的VNC LTS

Question

我有一台运行OS X 10.11.6的Mac和运行14.04LTS的Ubuntu EC2实例。 我试图让VNC从我的Mac上运行KDE。XQuartz启动，但我没有键盘或鼠标控制KDE。

端口5901是我的EC2安全组开放。

这是我的/etc/init.d/vncserver文件：

ubuntu@ip-10-0-1-107:~$ vi /etc/init.d/vncserver 

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartupTH="$PATH:/usr/bin/" 
export USER="ubuntu" 
DISPLAY="1" 
DEPTH="16" 
GEOMETRY="1600x1200" 
OPTIONS="-depth ${DEPTH} -geometry ${GEOMETRY} :${DISPLAY} -localhost" 
. /lib/lsb/init-functions 

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources 
xsetroot -solid grey 
vncconfig -iconic & 
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & 
x-window-manager & 
kdestartup & 

case "$1" in 
start) 
log_action_begin_msg "Starting vncserver for user '${USER}' on localhost:${DISPLAY}" 
su ${USER} -c "/usr/bin/vncserver ${OPTIONS}" 
;; 

stop) 
log_action_begin_msg "Stopping vncserver for user '${USER}' on localhost:${DISPLAY}" 
su ${USER} -c "/usr/bin/vncserver -kill :${DISPLAY}" 
;; 


restart) 
$0 stop 
$0 start 
;; 
esac 
exit 0 

开始vncserver的脚本：

ubuntu@ip-10-0-1-107:~$ sudo service vncserver start 
xsetroot: unable to open display '' 
vncconfig: unable to open display "" 
$DISPLAY is not set or cannot connect to the X server. 
* Starting vncserver for user 'ubuntu' on localhost:1...      Option "--login" is no longer supported in this version of gnome-terminal; you might want to create a profile with the desired setting, and use the new '--profile' option 

(x-window-manager:2591): Gtk-WARNING **: cannot open display: 
error: XDG_RUNTIME_DIR not set in the environment. 
Failed to parse arguments: Cannot open display: 

下面是关于OS X（服务器地址和证书改变了）ssh命令。

ssh -L -X 5901:127.0.0.1:5901 -N -f -l ubuntu x.x.x.x -i blahblahblah.pem 

这里的Ubuntu上运行VNC服务器：

ubuntu@ip-10-0-1-107:~$ ps -ef | grep vnc 
ubuntu 4289  1 0 17:13 ?  00:00:00 Xtightvnc :1 -desktop X -auth /home/ubuntu/.Xauthority -geometry 1600x1200 -depth 16 -rfbwait 120000 -rfbauth /home/ubuntu/.vnc/passwd -rfbport 5901 -fp /usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi/ -co /etc/X11/rgb -localhost

我使用它使用 X2Go客户“这个程序使用Qt 4.8.7版“。

它可能与屏幕。 尝试添加-X的ssh命令

ssh -X
