我想在我的电脑上设置多席位。我已经添加了第二个 VGA 适配器以使事情变得更容易/可能？

我们有：

  • Kubuntu Artful 17.10（KDE）
  • systemd
  • sddm（我们可能必须使用 lightdm，因为 sddm 缺少多座位功能）
  • Intel i5-4570S 片上图形
  • 非常老旧的 ATI RV710/Radeon HD4350/4550

让我们尝试记录最新的 Kubuntu/Ubuntu 版本的通用解决方案。

我很困惑，如果我启动 XI 则没有任何输入，seat0并且会出现随机噪音seat-tv。

我创建了一个新问题，因为现有的问题/答案要么专门针对硬件，要么在背景解释上不完整。至少我无法使用现有资源解决问题。

我创建了一个社区答案，因此请随意编辑下面的答案。

完成后，我可能会添加如何在 Seat-tv 上仅启动 Kodi，而无需显示管理器和窗口管理器。

答案1

在开始之前

  • 备份您的系统和/或等
  • 安装openssh-server并确保您可以从另一台电脑登录，以防您的本地登录不起作用
  • 禁用显示管理器的自动启动：sudo systemctl set-default multi-user.target
  • 为你的座位想一个好名字。惯例说它必须以 开头seat-。我选择seat-tv。

设置 udev 规则

  • 通过...添加规则

    • 使用loginctl路径上方的加号来创建 udev 规则，但我不推荐这样做。公交车 ID 保持不变吗？

      # gfx
sudo loginctl attach seat-tv /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0
sudo loginctl attach seat-tv /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/graphics/fb0
# hdmi audio
sudo loginctl attach seat-tv /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card2
# mele remote
sudo loginctl attach seat-tv /sys/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.0/0003:1915:0196.0008/input/input21
sudo loginctl attach seat-tv /sys/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.1/0003:1915:0196.0009/input/input22
sudo loginctl attach seat-tv /sys/devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.2/0003:1915:0196.000A/input/input23

    • 这将添加如下规则文件。如果 ID_FOR_SEAT 与给定值匹配，则规则将 ID_SEAT 设置为 seat-tv。

      $ cat /etc/udev/rules.d/72-seat-graphics-pci-0000_01_00_0.rules`
TAG=="seat", ENV{ID_FOR_SEAT}=="graphics-pci-0000_01_00_0", ENV{ID_SEAT}="seat-tv"

    • 或手动创建 udev 规则。我更喜欢使用 VendorID/ProductID 来识别。文件名应该以 72 开头，因为其他与座位相关的东西/lib/udev/rules.d是 71 或 73。

      $ cat 72-seat0.rules
# do I really need to set up anything for seat0?
# It should just grab anything not allocated to another seat?
# Intel GFX
# if TAG contains seat and vendor and product match the hex codes than set ID_SEAT to seat0

  • 您现在应该（在显示管理器重新启动后？）意识到以下情况

    • 分配给其他座位的输入在座位 0 上不再起作用
    • 分配给其他座位的屏幕应从系统设置/显示中消失
    • 音频设备也一样

设置 Xorg

  • 创建一个类似 /etc/X11/xorg.conf.multiseat 的目录，这样它就不会改变你的默认设置。
  • 使用以下命令获取当前 xorg 配置sudo Xorg :2 -configure

  • 创建文件/etc/X11/xorg.conf.multiseat/90-seat-tv.conf

    Section "Device"
        # get this from Xorg -configure
        Identifier  "Card0"
        Driver      "amdgpu"
        BusID       "PCI:1:0:0"

        MatchSeat      "seat-tv"
#    Identifier     "Seat-TV"

#EndSection

        Option          "Ignore" "yes"
EndSection

        Identifier      "use_seat_devices"
        MatchTag        "input_seat-tv"
        Option          "Ignore" "no"
EndSection

  • 我不知道所评论的条目。

  • 我是否需要为 seat0 设置类似的文件，或者使用默认文件就可以了？
  • TODO：服务器布局

测试

撤消

  • 暂时地
    • 再次启用窗口管理器sudo systemctl set-default graphical.target
  • 永久
    • 删除你的 udev 文件/etc/udev/rules.d/72-*
    • 删除你的/etc/X11/xorg.conf.multseat文件夹

现在怎么办？

  • 我错过了什么？
  • 服务器布局如何工作？
  • Mele 键盘不知为何没有连接到 Seat-tv？
