RHEL 6.8 and Quadro P5000 black screen after long lock and unlock screen

I am running RHEL 6.8 on DELL Precision Tower 7810 which has Quadro P5000 (Driver Version: 390.25). When I lock the workstation and come on the next day and login (unlock) i get empty black screen and I cannot do anything except hard shutdown. I have seen some posts regarding setting TerminateServer=true but that did not work. I am looking for help on this issue and appreciate your thoughts. I tried to attach the nvidia logs but i do not see any option.
