In fact, I've used this trick across many different linux distros including PCLinuxOS (one of my favorites thus far, and one my buddy devnet swears by), Kubuntu, Linux Mint and Ubuntu.

First, create a file in your home directory. Browse to /home/yourusername/ and create a file called .xmodmap. Open the file and paste in the following:

remove control = Control_L Control_R keycode 115 = Super_L Super_L keycode 116 = Super_R Super_R add control = Super_L Super_R

Now, open up terminal and type the following:

That will load the new file and your mapping should start to work. Not sure if your computer is different, might be. But hey give it a go.

Oh one thing I forgot, you'll want to add that to a startup script so you don't have to type "xmodmap ~/.xmodmap" every time you reboot your computer. It's different in KDE and Gnome I think. On my Ubuntu box I went to System > Preferences > Sessions which brought up a dialog box. On the "Startup Programs" tab click the "+Add" button. Name it whatever you want but in the command field type xmodmap ~/.xmodmap.

I hope that helps someone out there. If not, I'll have it here to refer back to down the road.
