Serious bug in Linux Mint 18.2 Cinnamon

[God_AL]

I have found bug in Linux Mint 18.2 Cinnamon. When I plug second display to my notebook, I can lock my screen, then close lid and main display turns off but second works.If I open lid, main and second displays will work and I will have ability to use my notebook on second display without input my password.

I doubt that Cinnamon has anything to do with it. Does anything show up in Mint Driver Manager for that card? From a quick search I think you want the 340 Legacy driver.

Don't dl it from nvidia's site ... that's a common beginner mistake. I know that looks obvious to a Windows user but in Linux those drivers rarely work.

But I have installed Open-source driver for Nvidia graphic card. And I have tried this bug on notebook with Intel graphic adapter, and this bug has worked.

Have you tried the closed Nvidia driver?
