Hi Geng,
Check what 'dmesg' returns. I suspect it is showing that there is a mismatch between the driver and the kernel module. Along the lines of:
NVRM: API mismatch: the client has the version 430.79, but
NVRM: this kernel module has the version 410.76. Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version.
If so then do the following:
sudo bash
uname -a
Linux blah 4.13.0-43-generic #48~16.04.1-Ubuntu SMP Thu May 17 12:56:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
update-initramfs -c -k 4.13.0-43-generic #replacing the 4.13... here with the version uname -a gave you.
Once that completes reboot and hopefully you should be good.
All the best
Ross
