# 备用方案（当前禁用）：

# 如果后续要启用 AMD 核显 + NVIDIA 独显切换，请取消下面整段注释。
|
||
#
|
||
# 重要提醒：
|
||
# 1) 先确认两张显卡的 PCIe Bus ID，再启用；否则图形界面可能无法启动。
|
||
# 2) 获取命令：lspci | grep -E "VGA|3D"
|
||
# 3) 示例输出常见为 "01:00.0"、"06:00.0"（16 进制）。
|
||
# 4) Nix 配置常用写法：PCI:<bus-dec>:<device-dec>:<function>
|
||
# 例如 01:00.0 -> PCI:1:0:0；06:00.0 -> PCI:6:0:0
