啟動時創建 X11VNC 伺服器初始化腳本不成功（手動啟動有效）
我已經安裝了 X11VNC 並在終端中正在執行的系統（執行 X 和 XFCE）上啟動它確實可以工作。我為此編寫了一個啟動腳本（使用 /etc/init.d/skeleton 中的骨架）。啟動後在終端中執行該腳本
service x11vnc start確實啟動了伺服器。雖然由於某種原因該程序沒有在後台執行，因此我不能再使用終端了。
但主要問題是：伺服器在啟動時啟動，我不太清楚從哪裡開始查找錯誤，我不確定（如果有的話）在哪裡可以找到顯示錯誤的日誌文件。

update-rc.d x11vnc defaults沒有幫助。還在ls /etc/rc?.d/幾個文件中顯示了我的腳本。但我得到以下
$ insserv -n x11vnc insserv: dryrun, not creating .depend.boot, .depend.start, and .depend.stop $ insserv x11vnc # returnes no errors
找了很久，終於找到了解決辦法。
使用
xinetd. 我再次刪除了初始化腳本/etc/init.d/並執行了以下操作。
apt-get install xinetd- 將內容創建到文件中
/etc/xinetd.d/x11vnc
service x11vnc { type = UNLISTED disable = no socket_type = stream protocol = tcp wait = no user = root server = /usr/bin/x11vnc server_args = -inetd -o /var/log/x11vnc.log -display :0 -forever -bg -rfbauth /etc/vncpasswd -shared -enablehttpproxy -forever -nolookup -auth /var/run/lightdm/root/:0 port = 5900 }
chmod a+x x11vnc- 重新啟動，它正在工作。
該標誌
-auth取決於您的登錄管理器。如果您需要找出標誌應該指向的位置，請使用：ps wwaux | grep auth. 這將列印路徑。在這裡找到解決方案。
