debian 10 gnome 3上的vnc灰度屏幕

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。然后我通过命令tightvncserver -geometry 1024x720 :1启动vncserver，下面是输出：

New 'X' desktop is debian:1

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

下面是~/..vnc/debian:1. the：

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

# Failed to parse arguments: Unknown option --login

正如您在最后一行中所看到的，有一个错误。

我通过注释这个文件中包含“-登录”的行来修正这个问题：) /usr/bin/x-terminal-emulator

然后重新启动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

然后让我们再次查看日志文件。

tail -f .vnc/debian\:1.log

# 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)

现在错误已经消失，我连接到vncserver，这些行出现在日志中：

我在vnc浏览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？

我已经搜索了很多这个rfbProcessClientNormalMessage: ignoring unknown encoding错误，但是我找不到解决方案。

顺便说一句，这是我的~/.vnc/xstartup：

#!/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。

Answer 1

为了克服这个问题，我使用了一个旧的解决方案中的~/.vnc/xstartup：

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startxfce4 &
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey &
vncconfig -iconic &

而且起作用了。

Answer 2

这个问题是关于使用gnome 3的debian的，但是其他的答案主要是关于使用xfce的debian。这个问题花了我很多时间。最后这位医生救了我。我使用debian 10安装了gnome，tigervnc作为vnc服务器。

#install vnc servrer
sudo apt install tigervnc-standalone-server 
#start vncserver and allow remote login
vncserver -localhost no :1
#check the port listen stat
netstat -tul | grep 5901

您可以使用tiger vnc查看器使用:1或:5901连接vnc服务器。

记住:1.在启动vnc服务器之前注销当前用户。2.在公共网络中应使用ssh隧道，而不要使用-localhost no。

#https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-debian-10
ssh -L 5901:127.0.0.1:5901 -C -N -l loginuser your_server_ip

使用localhost:1或localhost:5901连接到vnc服务器

更多内容:您可以看到文档https://help.ubuntu.com/community/VNC/Servers来查看如何在引导时启动TigerVNC vncserver。

Answer 3

在尝试从VNC到Debian 10时也出现了同样的问题。

显然，Debian 10使用Wayland和VNC有一些问题。

我的解决办法是让Wayland瘫痪。为此，编辑/etc/gdm3/daemon.conf并取消对行的注释

#WaylandEnable=false

所以相反，它会读到

WaylandEnable=false

然后重新启动服务器，启动VNC服务器，我可以连接到它。
