VNC 灰屏（Ubuntu 16.04，TightVNC，Xfce4）

VNC 灰屏（Ubuntu 16.04，TightVNC，Xfce4）

我已经使用 VNC 很多年了，但我不知道为什么有时会发生这种情况。在一台新的 Ubuntu 16.04 机器上，我首先尝试使用 Vino。它运行良好，但我认为它相当慢，所以我决定使用带有 Xfce4 窗口管理器的 TightVNC。然而，我再次得到了这个“灰屏”（我以前遇到过几次..）。
我的xstartup是：

#!/bin/sh

xrdb $HOME/.Xresources
xsetroot -solid grey
startxfce4 &

这里出了什么问题？是X server already running on display :1错误吗？那怎么办？那么多消息"RANDR" missing on display:1又是什么？ignoring unknown encoding

答案1

我发现https://bbs.archlinux.org/viewtopic.php?id=180965

并将我的 xstartup 更改为

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startxfce4 &

并且它有效！

答案2

Gnome 的工作配置

#!/bin/sh
#
# Config requires following packages:
# gnome-panel nautilus gnome-terminal metacity
#


export XKL_XMODMAP_DISABLE=1

unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
    
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey

gnome-session &
gnome-panel &

metacity &
gnome-terminal &

答案3

根据其他赞同的答案，我简单说一下：

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startxfce4 &

在我的~/.vnc/xstartup文件中，我能够本地连接。此外，我必须编辑/etc/vnc/conf添加以下行：

$localhost = "no";

让我的私有网络上的其他机器连接到 tigervnc 服务器（而不是仅仅localhost客户端）。

答案4

还要确保你有‘dbus-x11’已安装

sudo apt-get install dbus-x11

根据软件包信息网：此软件包包含 dbus-launch 实用程序，它会自动为每个用户的每个 X11 显示器启动一个 D-Bus 会话总线。如果还安装了 dbus-user-session 软件包，则它优先于此软件包。
