After I installed my new keyboard, I discovered that pressing Ctrl+Alt+Fn (where n is a number 1-12) keys no longer brings me to the tty screens (nothing happens), but sudo chvt 1
in the terminal emulator can start the tty. Meanwhile, Ctrl+Alt+F7 could bring me back to the x-window.
My keyboard is i-rocks IK6 (I didn't have such problem when using my old Logitech K120 keyboard)
How should I fix this problem? My system is Ubuntu 14.04 with Kernel 3.19.0-27-generic

I experienced a similar problem in my Dell Precision 5510 after a login loop that seems to happen due to a recent update of Ubuntu 14.04 LTS.
I finally found that the ESC key has a small Fn icon attached so I combined this with the Fn key and the blockade was released. Ctrl+Alt+F1 worked now and I could log in from the console.ç
çI have to fix now the issue of the login loop... I'll try with the suggestions I already found here.
