On my laptop (Toshiba Portege R705) the Mod4+P key combination toggles between different display modes: single monitor, mirror display, and extended display. I would like to disable this binding, because it can be annoying when pressed by accident. Moreover, there is already the Fn+F5 hardware key with the same functionality, so the binding probably comes from software. Unfortunatelly, I cannot find anything related in the Keyboard Shortcuts.

It appears to be related to the BIOS: see here and here.
This is hardcoded in gnome-settings-daemon and can be disabled in gconf by setting
/apps/gnome_settings_daemon/plugins/xrandr/activeto false. This workaround probably has a nasty side effect of breaking your real video switch key, if you have one.

This might be somehow related with this particular laptop, I don't remember having this issue on other hardware. – Adam Byrtek Apr 19 '11 at 21:22
