Hi, I have same issue on MSI CX61 2OD with Nvidia Geforce 740M, Ubuntu 14.04 64 bits, driver 331.38 (both tested and updates versions). Display hangs randomly when video is set to use Nvidia GPU, but it works fine when switched to Intel GPU.

It seems to stay that way until I switch to tty6 with ctrl+alt+f6 and then back to tty7 which has the display, this causes it to un-hang. This then happens back and forth. I am not sure but it might be triggered by clicking things, opening windows and such. The problem disappears when switching back to the open source driver. Should I try an even newer driver from nvidia, or is there any more information you need for troubleshooting?
