The root cause is that the nvidia_loaded is false cause in Power Saving Mode,
and nvidia_kmod_available is also false cause couldn't find nvidia.ko
correctly, so it wont' do set_offloading() which cause nvidia-settings is blank.
Now we used the linux-modules-nvidia-5.10.0-xxx-oem package to support secure
boot, and it will install the nvidia.ko in
/lib/modules/5.10.0-xxx-oem/kernel/nvidia-460/, so we need fix the source code
to detect the nvidia modules correctly.
else if ((intel_loaded || amdgpu_loaded) && !nouveau_loaded &&
(nvidia_loaded || nvidia_kmod_available)) {
fprintf(log_handle, "NVIDIA hybrid system\n");
/* Try to enable prime */
if (enable_prime(prime_settings,
&discrete_device, current_devices, cards_n)) {
/* Write permanent settings about offloading */
set_offloading();
}
