Comment 54 for bug 293213

I have the same problem with a Thinkpad X60s using KDE4.3.1 on openSUSE11.1.
The problem existed in 4.2 too.

In fact the Fn key is not recognised at all for a lot of the combinations. E.G
Fn+F2, Fn+F3, Fn+F4, Fn+F7, Fn+F9, Fn+F12. In Systemsettings when trying to enter a key combination to set a shortcut the Fn key is not recognised at all.

However it does work for some of the Fn combinations which I believe are controlled by the bios. E.G Fn+F5 (toggle radios), Fn+F7 (toggle external screen), Fn+ScrLk (toggle Numlock), Fn+PgUp (toggle thinklight), Fn+Home (increase screen brightness), Fn+End (decrease screen brightness).

These did work in Gnome so it seems to be a KDE thing. An explanation of the
Thinkpad Fn keys can be seen at

If you require me to test or provide further info let me know.
