debian 10 gnome 3 上的 vnc 灰屏

Question

我描述了我到底做了什么：

首先，我安装了 debian10-netinstall。

然后我通过“Tasksel”命令安装了 Gnome。

然后我使用这个教程来安装 vnc 服务器。然后我通过这个命令启动 vncserver，这tightvncserver -geometry 1024x720 :1是输出：

New 'X' desktop is debian:1

Starting applications specified in /home/parsa/.vnc/xstartup
Log file is /home/parsa/.vnc/debian:1.log

这是 ~/.vnc/debian:1.log ：

parsa@debian:~$ tail -f .vnc/debian\:1.log

# Failed to parse arguments: Unknown option --login

正如您在最后一行中看到的那样，有一个错误。

我通过评论该文件中包含“--login”的行来解决这个问题:)) /usr/bin/x-terminal-emulator

然后我重新启动了 vncserver ：

parsa@debian:~$ tightvncserver -kill :1
Killing Xtightvnc process ID 910
parsa@debian:~$ tightvncserver -geometry 1024x720 :1

New 'X' desktop is debian:1

Starting applications specified in /home/parsa/.vnc/xstartup
Log file is /home/parsa/.vnc/debian:1.log

然后再次让我们查看日志文件

tail -f .vnc/debian\:1.log
# watch_established: "/org/gnome/desktop/interface/" (establishing: 1)
# watch_established: "/org/gnome/settings-daemon/peripherals/mouse/" (establishing: 1)

# unwatch_fast: "/org/gnome/terminal/legacy/" (active: 0, establishing: 1)
# watch_established: "/org/gnome/terminal/legacy/" (establishing: 0)

现在错误消失了，我连接到 vncserver ，这些行出现在日志中：

我在 vnc 查看器中看到一个带有黑色 X 光标的灰色屏幕：

你能帮我解决这个问题吗？

我在谷歌上搜索rfbProcessClientNormalMessage: ignoring unknown encoding了很多这个错误，但找不到解决方案。

~/.vnc/xstartup顺便说一下，这是我的：

#!/bin/shxrdb $HOME/.Xresources
xsetroot -solid grey
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
# x-window-manager &
gnome-session &

谢谢你。

Answer 1

尝试通过 VNC 连接到 Debian 10 时遇到同样的问题。

显然 Debian 10 使用 Wayland，而 VNC 存在一些问题。

我的解决方案是禁用 Wayland。为此，请编辑/etc/gdm3/daemon.conf并取消注释该行

#WaylandEnable=false

这样它就会读取

WaylandEnable=false

然后重新启动服务器，启动 VNC 服务器，我就可以连接到它了。
