I have an application that binds CTRL+ALT+F7, but my linux machine seems to catch the keystroke.

Is there a way to rebind/disable this key? A recompile of the kernel is an acceptable answer.

The distributions in question are Fedora 16 and Ubuntu 11.10.

I don't have any specific advice, but I think, as CTRL+ALT+Fn is bound only under the X-Windows System, that the kernel won't be related to it in any way, and that you will probably be luckier trying to tweak the X11 configuration. – njsg Mar 14 '12 at 16:48

Place this in your /etc/X11/xorg.conf file to disable VT switching with Ctrl+Alt+Fn:

Section "ServerFlags"
    Option "DontVTSwitch" "on"
EndSection

You will also need the following to cause events to be passed through to clients connected to the display:

Section "InputClass"
    Identifier "keyboard defaults"
    MatchIsKeyboard "on"
    Option "XKbOptions" "srvrkeys:none"
EndSection

(that last bit is untested, sourced from http://ubuntuforums.org/archive/index.php/t-1779702.html)

This does not forward the combination to the window, X still catches it. – Jes Mar 14 '12 at 19:25
I did some Googling and found you need to add something else to the config file. Let me know if it works. – Sam Morris Mar 15 '12 at 11:49

After a few months of having to run Windows I have finally tested this on Lubuntu 12.04, where the IntelliJ IDEA window still does not catch the keystroke. – Jes Aug 14 '12 at 20:52
Using the two settings was both required for me, and worked for me. (on centos). ctrl-alt-f7 is now showing the usages inline in intellij :). – Rob Dawson Apr 15 at 0:11

You can disable this by going to System settings -> keyboard layout -> option. under miscellaneous compatibility options check "special keys Ctrl+Alt+<key> handled in server".

I checked this and Ubuntu does not catch any combination of Ctrl+Alt+... . but still idea does not catch Ctrl+Alt+F7 and the problem still exits!!!.

You are right Ubuntu does not catch it, but I suspect that the X server does. – Jes Mar 26 at 14:45
