Kennedy Baird's questions

我知道这是一个常见问题，但我遇到了麻烦..

我正在运行 Ubuntu 18.04。我必须nomodeset在启动时使用 grub 中的参数才能正确启动。

uname -mrs

Linux 4.15.0-23-generic x86_64

lspci | grep VGA

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Vega [Radeon RX Vega M] (rev c0)

运行ubuntu drivers devices没有结果

lshw -c video

我尝试添加amdgpu.dc=1到引导参数，但没有改变任何东西。

升级到内核 4.16 并且没有任何变化，尽管运行 glmark2 对 CPU 的占用较少
