我无法让笔记本电脑(Lenovo Legion 5)识别我的第二个屏幕。它有 Nvidia RTX 3060 和第二张卡:
❯ lspci -nnk | grep "VGA\|'Kern'\|3D\|Display" -A2

我没有任何 /etc/X11/xorg.conf 文件。如果我用 生成了一个文件nvidia-xconfig
,则在重启时会出现闪烁的光标。
BIOS 中已启用可切换显卡。
当我通过 HDMI 连接屏幕时,什么也没有发生...并且热键 Win+P 或 Fn+F7 没有任何反应。
任何想法 ?
答案1
经过几个小时的思考和各种不同的想法,我终于成功让它发挥作用,并给出了“我的”解决方案。虽然没有什么黑魔法,但对我来说它确实有效......
- 不要使用 Nvidia 专有驱动程序(此处为 nvidia-tesla510)或任何其他软件包,如 optimus、prime、bumblebee 等。为安全起见:删除所有当前 Nvidia 驱动程序,无一例外:
sudo apt purge nvidia-*
。如果有任何关于依赖项的错误,请将其删除。然后重启。验证您的系统上没有安装任何 Nvidia 软件包(包括 Cuda)。使用 删除任何多余的软件包apt autoremove
。我个人建议不要安装任何非稳定存储库官方分发的软件包。重启。 - 按照 Kali 安装指南进行操作,基本上:
sudo apt update
sudo apt -y full-upgrade -y
[ -f /var/run/reboot-required ] && sudo reboot -f
sudo apt install -y nvidia-driver nvidia-cuda-toolkit
- 对于已连接第二个屏幕的屏幕检测:
xrandr -q
。您应该会在列表中看到已连接的第二个屏幕。但是,即使这样,也不足以让信号通过第二个屏幕。 - 您现在可以重新启动(可能没什么用——我知道)
- 写下你自己的
/etc/X11/xorg.conf
,灵感来自:http://us.download.nvidia.com/XFree86/Linux-x86/375.39/README/randr14.html。或者您可以使用包nvidia-xconfig
(apt install nvidia-xconfig
)然后启动: 。您可以验证是否已写入sudo nvidia-xconfig
新文件。这是我的:/etc/X11/xorg.conf
❯ cat /etc/X11/xorg.conf

如果您拥有基于英特尔的混合显卡,那么您将看到“intel”而不是“amdgpu”。
- 重启,祈祷,你就大功告成了。如果它不起作用(光标闪烁、屏幕变黑……),请进入另一个终端(Alt+F2),删除
xorg.conf
,重启,然后继续责怪 Nvidia、Intel、AMD 和您最喜欢的制造商对 Linux 的良好软件支持,尝试寻找其他解决方案。祝你好运。

(Legion 5),Amd 按 F9 进入 Bios 设置菜单并选择独立显卡并重新启动系统。
