我有一台无头服务器，我正在尝试设置 VNC 连接以便使用 GUI 访问它。现在我只能通过 ssh 获得 root 访问权限。
我已遵循这里给出的大部分说明从命令行启用远程 VNC？。在解决了很多问题之后，我终于可以运行 vino-server 了，但是当我连接 VNC 客户端时，屏幕却变黑了。
到目前为止，我安装了 vino 和 ubuntu-desktop。之后我执行了以下命令：
gconftool-2 --set --type=bool /desktop/gnome/remote_access/enabled true
gsettings set org.gnome.Vino erequire-encryption false
gsettings set org.gnome.Vino lock-screen-on-disconnect false
我vino-preferences点击了允许查看和控制桌面。还取消了确认传入连接的勾选。
我运行 vino/usr/lib/vino/vino-server并且这是输出：
(vino-server:8140): EggSMClient-CRITICAL **: egg_sm_client_set_mode: assertion 'global_client == NULL || global_client_mode == EGG_SM_CLIENT_MODE_DISABLED' failed
** (vino-server:8140): WARNING **: Your XServer does not support the XTest extension - remote desktop access will be view-only

在谷歌搜索了黑屏问题之后，我还安装了 gnome-core 并附加了 .vnc/Xstartup 文件，如下所示：
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
gnome-session –session=gnome-classic &
gnome-panel&
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -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 &
