Comment 15 for bug 1243733

Thank you, Camilio! I had the same problem, and tried the above xev/xmodmap fix and eventually got it to work. But my keymap was different --

Fedora 20, KDE. Machine is an HP laptop, Pavilion dv6 (dv61-7000).

1. PrtSc does nothing.

2. xmodmap -pk | grep Print returns
        191 0xff61 (Print) 0xff15 (Sys_Req) 0xff61 (Print) 0xff15 (Sys_Req)
        218 0xff61 (Print) 0x0000 (NoSymbol) 0xff61 (Print)

3. xmodmap -e "keycode 191 = Sys_Req"

4. PrtSc now correctly lauches ksnapshot.

5. xmodmap -pk | grep Print now returns
        218 0xff61 (Print) 0x0000 (NoSymbol) 0xff61 (Print)
