System hang at "shutdown" or "restart" - Ubuntu 18.04 daily build

I tried 18.04 daily build today, after I installed the Nvidia display driver, the system won’t shutdown or restart.

My monitor goes into the sleep mode (power saving mode, - no signal), however the system is still running, the fans’ on, keyboard and mouse led all on. have to press the power button for couple of seconds to force system to shutdown.

My system doesn’t have this problem in 16.04 with nvidia 384 driver. My graphic card is Nvidia Quodra K2200.

anyone have the same problem? any solutions?
