I've just installed my lenovo g400s with Ubuntu 14.04 64bit. The problem is when I want to close tab by pressing Ctrl + f4, it open tty and I cannot go back to desktop although I press Ctrl + Alt + F7/F8. How to resolve this problem?

And one more thing, I want to make Fn key usable, because it's no need to press Fn key to use special function in F1-F12 now. Thank you all.


I've solved my problem. Just turn off hotkeys in BIOS fix all the problem.
