TigerVNC 配置 Ubuntu 20.04,黑屏

我安装了TightVNCUbuntu20.04* 机器以便从我的 macbook pro 远程使用它。我已关注本教程

它适用于fce4桌面。但我有一个黑屏每当我尝试使用gnome 桌面有了它:我试图改变配置如下这个问题,但似乎没有什么效果。

这是〜/ .vnc / xstartup

#!/bin/sh

unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

export XKL_XMODMAP_DISABLE=1
export XDG_CURRENT_DESKTOP="GNOME-Flashback:GNOME"
export XDG_MENU_PREFIX="gnome-flashback-"


[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &

gnome-session --builtin --session=gnome-flashback-metacity --disable-acceleration-check --debug &
nautilus &
gnome-terminal &

此外,我的黑屏上出现了错误信息:

无法更新 ICEAuthority 文件 /run/-/user//-ICEAuthority

这可能是配置或权限错误,但经过两天的尝试后,我开始失去信心了。

答案1

我只是按照你的配置做了一些改动,我想我最终得到了你想要的:

在此处输入图片描述

。我的改变是:

我修正了以下行:

ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1

经过

ExecStartPre=/usr/bin/vncserver -kill :%i > /dev/null 2>&1

前面没有‘-’字符/usr/bin

除此之外,我将用户名称的引用从“ben”更改为我的用户:

User=ben
Group=ben
WorkingDirectory=/home/ben

PIDFile=/home/ben/.vnc/%H:%i.pid

因此,我的文件最终为:

User=my_user
Group=my_user
WorkingDirectory=/home/my_user

PIDFile=/home/my_user/.vnc/%H:%i.pid

假设您的用户实际上是ben,我认为您的主文件夹中有一些文件权限有限/home/ben。您可以检查这个问题了解有关修复它的详细信息。也许您需要使用命令将此目录中文件的所有权授予用户 ben,chown或者仅使用更改权限chmod

答案2

我通过从 /etc/gdm3/custom.conf 中取消注释“WaylandEnable=false”获得了它

然后

sudo apt update
sudo apt install xserver-xorg-video-dummy
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak # this file may not exist so if there is an error, it can be ignored
sudo cp /etc/X11/vncserver-virtual-dummy.conf /etc/X11/xorg.conf

注意:按照这些步骤操作会导致任何连接的显示器显示空白屏幕。如果您需要使用显示器,请运行 sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.dummy 并重新启动
