I need CUDA and an external screen for my Blender job. But I can’t have both because Nvidia driver issue. Here is the result of mhwd graphic driver that I have tried:
video-hybrid-intel-nvidia-450xx-prime
CUDA is detected but external screen goes black
video-nvidia-450xx
CUDA is detected but main screen goes black
video-linux
+video-modesetting
CUDA is gone but both screen works
My laptop is Acer Nitro 5 (AN515-52)
