如何选择主 GPU？如何在 Radeon GPU 上进行输出？

  • 772

情况：台式电脑配有 AMD CPU、iGPU 和 PCIe 上的 Radeon GPU。EndeavourOS 带有 systemd-boot（但也尝试过使用 GRUB 的 Pop OS）。

在 BIOS 设置中，PCIe GPU 被选为主要 GPU。

引导加载程序（systemd-boot 和 GRUB）从主板连接器（iGPU）和 Radeon 连接器提供 VGA 输出。

但是当内核接管时，输出仅来自 iGPU。无论是启动消息还是之后通过 SDDM、wayland、KDE ​​Plasma。当显示器连接到 PCIe GPU 时，显示器会打开但屏幕空白。

如果我从 BIOS 禁用 iGPU，那么两个 GPU 上都不会输出。

    显然这不是驱动程序或配置问题。华硕主板上的 BIOS 版本（如 1809、1811）可能存在 PCIe GPU 问题。

    解决方法是升级您的 BIOS。
