我有一台 DELL Precision T5610 工作站，安装了 Gigabyte AMD Vega 56 显卡，运行双启动 Windows 10 + Linux 环境。显卡通过 DisplayPort 电缆连接到分辨率为 5120x1440 像素的 DELL 4919UW。
该系统在 Windows 10 上运行良好。Fortnite 以原始分辨率运行，峰值为 90 fps。
Linux 应该是用于编程的 Ubuntu 18.04。我只需要 2D 硬件加速窗口管理器，不需要 3D，不需要 Vulkan，不需要花哨的 ding 位。我只需要能够在超快速设置中使用 Atom、网络浏览器和许多终端。
我能够使用模式设置安装程序 DVD 中的 grub 参数。重新启动后，安装更新系统没有硬件加速图形 - 它像 1980 年代一样慢...
nomodeset 会自动添加到 grub 中，这似乎会禁用 amdgpu 驱动程序，因此所有窗口都会以软件形式呈现，并且速度很慢，无法使用。
从 grub 中删除 nodmodeset 后，系统会卡在黑屏上，无法启动到 WM。启动的唯一方法是使用恢复模式并选择恢复。但速度又很慢。
dmesg 报告VGACON 禁用 amdgpu 内核模式设置并尝试在 grup 中传递 amdgpu.dc=0 选项。仍然没有成功。在 grub 中禁用 VGA 图形控制台 - 没有变化。
安装了 AMD 的驱动程序，包括 amdgpu-pro-install 和 amdgpu-install（用于 FOSS 驱动程序）。仍然没有成功。系统无法启动或运行缓慢。FOSS 驱动程序只能识别 3440x1200 像素，而不能识别 5120x1440 像素。
由于工作站在 Windows 10 下使用 Fortnite 运行良好，我认为我可以排除所有与电源相关的问题。
