![VNC 灰屏(Ubuntu 16.04,TightVNC,Xfce4)](https://linux22.com/image/903667/VNC%20%E7%81%B0%E5%B1%8F%EF%BC%88Ubuntu%2016.04%EF%BC%8CTightVNC%EF%BC%8CXfce4%EF%BC%89.png)
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。
