• Setup discrete graphic card: first install nvidia driver on your device and then open file /lib/modprobe.d/nvidia-kms.conf, delete or comment out the line "options nvidia-drm modeset=1" to enable kernel mode driver if you does not find nvidia kernel mode driver loading using dmesg, it solves the nvidia grapic card running hot and frame loss issue.

• Make i8kctl loads at boot time: add line line i8k to /etc/modules
• You can also messing with fan curve by adjusting this file /etc/i8kmon.conf
