tigervnc vnc 会话中缺少 KDE 面板

  • 772

我想获得对tigervnc 服务器的VNC 访问权限。两台笔记本电脑都运行 ArchLinux sddm KDE xorg（不是 wayland），我花了一天的时间才让服务器运行起来，而且 Dolphin 正在打开——仅此而已。我的 xstartup 文件包含以下内容：

    #!/bin/sh
    # Run a generic session
    if [ -z "$MODE" ]
    then
            xsetroot -solid grey & #has impact on the background
            export XKB_DEFAULT_RULES=base #no impact
            export QT_XKB_CONFIG_ROOT=/usr/share/X11/xkb #no impact
            kstart5 plasmashell & #no impact
            konsole & #is opening
            firefox & #is opening
            xrandr --dpi 144 & #see no difference
            dbus-launch startplasma-x11 #this is what moves the needle rn :)

    fi

我启动服务器vncserver :1 -depth 24 -geometry 1920x1080 并使用 remmina 客户端、google vnc 查看器和带有 ip:port 的 KRDC 访问服务器，并且 vnc 传输的外观非常漂亮，反应时间也很好。只是我无法右键单击桌面并且没有任务栏/等离子面板丢失。

我可以使用诸如Firefox之类的终端启动应用程序，例如，不能以某种方式使用等离子面板。注销屏幕也可以正常工作，我可以使用完美的图形和动画注销和登录。

在此处输入图像描述

所以我的问题是：如何在 vnc 服务器上显示等离子面板 + 桌面，或者如何连接到 tty1 上的原始桌面？

（如果我直接访问服务器笔记本电脑，它可以正常工作，面板会显示并且运行流畅。我还在几秒钟内启动并运行了一个 gnome vnc 服务器 - 只是我爱上了 KDE，它实际上运行更流畅/更快/通过 vnc 比 gnome 反应）

  1. Best Answer

    所以我为我找到了 2 个解决方案 - 如果有人遇到同样的问题。

    1. 使用 Tigervnc 或 Tightvnc

    2. 用 x11vnc

    两者的区别在于 1. 启动自己的 x11 服务器和 2. 连接到现有桌面。使用 1. 我可以设置任何我想要的屏幕分辨率，并尽可能多地启动硬件可以处理 - 没有任何限制。

    1. 在第一次启动tigervnc 后，在~/.vnc 文件夹中出现一个xstartup 文件，该文件必须包含以下内容才能启动kde plasma x11 会话：

        #!/bin/sh
    # Run a generic session
    if [ -z "$MODE" ]
    then
            xsetroot -solid grey &   #set the background picture
            export XKB_DEFAULT_RULES=base & #both should be needed for keyboard signals
            export QT_XKB_CONFIG_ROOT=/usr/share/X11/xkb & 


    #       export $(dbus-launch) &
    #       exec startplasma-x11&
    #       kstart5 plasmashell &
            konsole & #starts konsole (kde terminal)
            firefox & #starts firefox
            ksysguard & #starts the kde system monitor
    #       xrandr --dpi 144 & # 
            kstart5 plasmashell & #adds a task bar to the windows
            dbus-launch startplasma-x11  #starts the actual window + Dolphin

    #       /opt/kde/bin/startkde &   
    fi

    所有已注释掉的选项（还有更多是结果不好或根本没有结果的试验）

    vncserver :1 -depth 24 -geometry 1920x1080以 FullHD 启动服务器vncserver -kill :1并将其终止（1 代表会话，并且在您之前运行该命令的次数越多）我可以使用带有 ip 和端口的 remmina gui 客户端连接到它 - fe 192.168.1.4:5901（标准端口，您可以找到您的服务器IP与ip addr）

    仍然没有任务栏，也没有可用的后台桌面选项 - 但它可以工作，我可以移动和调整窗口大小并使用终端启动新窗口 - 如果你找到解决方案 - 很高兴听到它:)

    2. 非常简单/快速，只需安装 x11vnc ( sudo pacman -S x11vnc) 并在服务器上启动它x11vnc -many -display :0

    比连接 remmina 客户端和 ip（无端口）（fe 192.168.1.4）-繁荣完成-原始监视器的图片。（在我的情况下只是高清分辨率 - 但使用桌面和任务面板）

    如果我跳过命令 -many，会话仅可用于一个连接，并在我断开 vnc 客户端后结束，并且每次我想连接时都必须重新启动。有很多它留下来。重新启动后自动启动 x11vnc 完成以下操作：

    我已经失去了几个小时。我认为以 root 身份启动 x11vnc 不是一个好主意。这[email protected]- 在 Arch Linux 上这个文件夹所在的位置/usr/lib/systemd/system/- 只需创建一个文件[email protected]并包含以下内容。

        [Unit]
    Description=VNC Server for X11
    Requires=display-manager.service
    After=display-manager.service

    [Service]
    Type=forking
    ExecStart=/usr/bin/x11vnc -rfbauth /home/user/.vnc/passwd -ncache 2 -forever -shared -bg -display :0
    Restart=on-failure
    RestartSec=10
    User=%I

    [Install]
    WantedBy=multi-user.target

    可以启动一次

    systemctl start [email protected]

    您可以在其中将“用户”更改为您的用户，它可以在启动后自动启动

    systemctl enable [email protected]

    它永远不会失败（也许关于重启的行可以省略）。

    是的 - 就是这样:)

    编辑：我现在在许多 Arch linux 服务器上对其进行了测试，出于稳定性原因，应该使用 git 版本（yay -S x11vnc-git而不是yay -S x11vnc），因为通过在特定计算机上编译它，编译器可以针对已安装的系统对其进行完美优化。在大多数情况下不是必需的，但对于某些硬件是必需的。

    此外，-ncache 2 标志通过仅将差异发送到上一张图片来加速/保护 vnc 服务器的带宽，但如果带宽无关紧要，它是可选的并且没有它也可以正常工作。
