升级到 ubuntu 23.04 后分辨率低并且丢失了第二个屏幕

升级到 23.04 后，第二个屏幕变为第一个屏幕的镜像。分辨率固定为 1024x768~76Hz，无法更改。

amdgpu 似乎还没有适用于 23.04 的驱动程序。有没有办法加载 radeon 驱动程序？我可以降级到 22.10 或 22.04LTS 吗？

inxi 显示 radeon 驱动程序未加载。

尝试重新安装 amdgpu-install

amdgpu-install -y --usecase=graphics

从 xorg 日志中获取 grep

基于这个帖子，

  1. 下载最新的 amdgpu-install_5.6.50600-1_all.deb
  2. 由于我不需要 i386 依赖项，我只需尝试忽略它们，方法--no-32是排除 i1386 版本的驱动程序，然后amdgpu-install为新内核重建 initramfs。示例：amdgpu-install --usecase=graphics -y --no-32 您仍会看到一堆可能缺少固件的警告，但对我来说都很好。
  3. 重启
