I have configured my X keyboard heavily, but it has worked for many, many
years - until now :-(

I have also another BIG problem: 
Alt-F1 ... Alt-F10 is switching to the VT console 1 .. 10 
Without using the control key!
So, I cannot use the XFCE functions on Alt-F1 ... Alt-F10 any more :-(

For example: Alt-F6 should maximize a window vertically, but it switches
to the VT (text) console 6!

Though I have:

framstag at diaspora:~: xmodmap -pke | grep F6
keycode  72 = F6 NoSymbol F6

BUT this beviour only appears some time after login!
Shortly after login Alt-F6 works as expected.
Something is messing up my keyboard, but what and why?
