最近我在天选air2025（ASUSTeK COMPUTER INC. TX Air FA401KM_FA401KM/FA401KM）上尝试了 CachyOS，开箱即用的高性能arch衍生版。使用外接显示器时它运行得非常完美（此时会激活 dGPU——NVIDIA 5060m）。
然后我断开外接显示器，系统依然运行得很好。然而在重启笔记本后，我发现内置显示屏在sddm成功登录后画面会完全冻结。此时重新插入外接显示器，内置显示屏依然是冻住的，只有外接显示器正常。
我怀疑这是由于 AMD Replay 技术（PSR2）与显示面板的不兼容导致的。这个问题只会在 dGPU未被激活，单独使用 iGPU时出现，也就是最前面说的：在插入外接显示器的时候启动系统时没问题的。
我尝试过在内核参数中添加 amdgpu.dcfeaturemask=0x0 amdgpu.dcdebugmask=0x210，但没有任何效果。下面是启动日志：
