How to install nvidia graphic driver instead of nouveau opensource driver?

As the topic, I want to install nvidia commercial driver. I followed the instructions from slackbuilds.org.
I checked my hardware first using command " lspci -nn -d 10de:" and got result:
PHP Code:01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP104BM [GeForce GTX 1080 Mobile] [10de:1be0] (rev a1)
01:00.1 Audio device [0403]: NVIDIA Corporation GP104 High Definition Audio Controller [10de:10f0] (rev a1)
and then, I installed some packages such as nvidia-driver, nvidia-kernel, nvidia-firmware and libxnvctrl,
and of course add nouveau driver into blacklist in /etc/modprobe.d/disable_nouveau.conf:
PHP Code:blacklist nouveau
options nouveau modeset=0
However, when I reboot, the system can't work, some system message looks like:
PHP Code:[ 7.610784] i915 0000:00:02.0: enabling device (0000 -> 0003)

In fact, I can't see the message on the screen since the nvidia driver loaded(I guess from then).
I have to reboot use a usb stick to seen the log file from /var/log/message.
I want to know, what's wrong about it, why it said no crtc?
I hope some one have a successfully experience about nvidia driver. And my kernel version is 5.4.25

Thanks and best regards.
