Hi there @robin.kim and welcome to the NVIDIA developer forums.
In the BIOS leave the stting on “Hybrid Graphics”.
Then the first thing to check is if the NVIDIA driver is installed correctly. Does the command sudo nvidia-smi give you proper output?
The next step would be run nvidia-settings and check if you can see “PRIME profiles”, select either NVIDIA Performance Mode or On-Demand, both should work. Preferably Performance Mode. Then reboot.
If that still does not help I recommend checking out the dedicated Linux category here in the forums.
Thanks!
