我有一台集成 Intel 4600 HD 图形控制器的台式机。昨天我安装了 AMD Radeon RX 560 显卡，它在 Windows 中运行完美。但是当我在 ubuntu 22.04 中启动时，我看到的是空白屏幕而不是登录屏幕。我尝试从 amd 网站安装 amd gpu 驱动程序，但这并没有改变任何东西。这是 Xorg 文件显示的内容：

我通过在 /etc/X11/xorg.conf 目录中添加以下内容的 10-amdgpu.conf 文件解决了我的问题：
Section "Device"
Identifier "AMDGPU"
Driver "amdgpu"
Option "TripleBuffer" "true"
Option "TearFree" "true"
Option "DRI" "true"
EndSection
