Geforce GTX 1650 - nvidia-settings“错误：无法从任何可用系统加载信息”

我正在尝试使用 HDMI 线将外接显示器插入我的笔记本电脑，以实现双屏。

当我这样做时，什么都没有发生，外接屏幕根本无法识别。我认为这是因为我的笔记本电脑的视频卡驱动程序没有正确安装/启用。

要安装驱动程序，我所做的就是

sudo add-apt-repository ppa:graphics-drivers/ppa

然后使用“附加驱动程序”GUInvidia-driver-430在我的系统上进行设置。

我重新启动了机器，但什么都没有改变，外接显示器仍然无法识别......

当我尝试启动时nvidia-settings，出现此错误：

ERROR: Unable to load info from any available system

以下是 的输出nvidia-smi：

我正在运行带有 5.0.0-20-generic 内核的 Xubuntu 19.04，并且已在 BIOS 中禁用“安全启动”。

这真的很烦人...有人能帮我解决这个问题吗？提前谢谢

答案1

看起来您的系统中已选择 Intel GPU（并在 BIOS 中禁用）作为主要 GPU。

运行以下命令：

sudo nvidia-xconfig

然后运行此命令来选择 Nvidia：

sudo prime-select nvidia

或者，对于英特尔，使用以下命令：

sudo prime-select intel

我终于找到了解决这个问题的方法。

  1. 从 PPA 安装驱动程序。有很多文章介绍如何操作。
  2. 删除/etc/X11/xorg.conf。
  3. 切换到tty3并关闭 Xorg: sudo systemctl stop gdm(适用于 Ubuntu)
  4. xorg.conf从日志中制作骨架文件：sudo Xorg -configure :0
  5. 复制xorg.conf.new到等：sudo cp /root/xorg.conf.new /etc/X11/xorg.conf

  6. 在“设备”部分更改驱动程序名称：

    Section "Device"
    ### Available Driver options are:-
    ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
    ### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
    ### <percent>: "<f>%"
    ### [arg]: arg optional
    #Option     "SWcursor"              # [<bool>]
    #Option     "HWcursor"              # [<bool>]
    #Option     "NoAccel"               # [<bool>]
    #Option     "ShadowFB"              # [<bool>]
    #Option     "VideoKey"              # <i>
    #Option     "WrappedFB"             # [<bool>]
    #Option     "GLXVBlank"             # [<bool>]
    #Option     "ZaphodHeads"           # <str>
    #Option     "PageFlip"              # [<bool>]
    #Option     "SwapLimit"             # <i>
    #Option     "AsyncUTSDFS"           # [<bool>]
    #Option     "AccelMethod"           # <str>
    #Option     "DRI"                   # <i>
Identifier     "Card1"
Driver         "nvidia"
BusID          "PCI:1:0:0"

  7. 重启

此后nvidia-settings即可正常启动。
