Disabling Print Screen key

["Luis Finotti" <finotti.deb@gmail.com>]

Hi,

My Print Screen key is too close to BackSpace, so I keep pressing it
by accident.  I use KDE, and this makes "KSnapshoyt" pop up.  (In
fluxbox, it sends the content of the terminal to the printer.)

I checked the key assignments of KDE, and I found no shortcut for the
PrtSc key, and even defining a different application for that key
would still make (only) KSnapshot pop up.  (KSnapshot was assigned to
Crtl+PrtSc, and I disabled it too, just in case.)

My Google searchs did not help (even on this list).

So, I decided to disable the key.

Using "xev", I saw that the keycode was 111:

....
KeyRelease event, serial 31, synthetic NO, window 0x3600001,
    root 0x91, subw 0x0, time 482199882, (485,527), root:(489,552),
    state 0x0, keycode 111 (keysym 0xff61, Print), same_screen YES,
    XLookupString gives 0 bytes:
....

Indeed, "xmodmap -pk" gave:

...
    111         0xff61 (Print)  0xff15 (Sys_Req)
...

So, I did "xmodmap -e "keysym Print = BackSpace"".  Now, "xev" gives:

....
KeyRelease event, serial 31, synthetic NO, window 0x3400001,
    root 0x91, subw 0x0, time 482660638, (-260,401), root:(838,426),
    state 0x0, keycode 111 (keysym 0xff08, BackSpace), same_screen YES,
    XKeysymToKeycode returns keycode: 22
    XLookupString gives 1 bytes: (08) "
....

and  "xmodmap -pk" gives:

...
    111         0xff08 (BackSpace)
...

But still, KSnapshot pops up, and the backspace has no effect.

Any suggestions or ideas (other than remove the key physically)??

Thanks,

Luis
