I didn't know where to put this question. It seems to be in between Hardware and Software, though more Software than Hardware.
I'm using Gnome Terminal specifically, but I realize that this problem also occurs with RXVT and ATerm, but XTerm is exempt, because you can map your Windows key to your Meta key by adding these two lines to your .Xdefaults:
I did some more research and found that you need to tell loadkeys to use the Windows keys as Meta keys, but I was unsuccessful in doing so, as
echo "keycode 156 = Meta_X" | loadkeys
...did not work. It doesn't give me any messages.
Thanks in Advance
