After I installed my new keyboard, I discovered that pressing Ctrl+Alt+Fn 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

p.s. I'm not an English Speaker so please forgive my English and ask me for details if I failed to express clearly...

  • please try sudo service tty1 restart and then try to login to tty using Ctrl+Alt+F1....any change?? – Ravan Sep 21 '15 at 13:18

    Does your keyboard have a Fn combination key? This can be an issue if the OS autoenables the Fn key, in which you have to press it to disable it (ie, Ctrl + Alt + Fn + F1 might work). – Zzzach... Oct 19 '15 at 2:57

    The kbd has a Windows and application keys disabled function. It is turned on and off using [Fn][F11]. – NZD Nov 13 '15 at 20:04

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.


The i-rocks IK6 Crystal USB Keyboard has, what they call, a Windows and application keys disabled function.

The function is turned on and off using Fn + F11.

There is even a small Windows icon on the F11 key.
