Whenever I select prime-select nvidia, my OS is unable to boot up. It gives a blank screen. I have to everytime switch back to prime-select intel to get the display back on.
Laptop Acer-Nitro5 GPU RTX 3050Ti and Intel Integrated GPU.
I recently reinstalled nvidia-driver-520, it was working fine until I restarted the system when the nvidia-smi error cropped up. This keeps happening after every reboot.
Any help would be greatly appreciated.
Can someone please help me out why this is happening?
