I installed xfce4-terminal 0.6.3 on my Debian system. I launched it. I started emacs within it just as you have indicated. For me C-SPC works fine and I can set the mark using it. This leads me to believe that for some reason your xfce4-terminal does something different that is problematic for you. I don't know the answer but I would concentrate on the question of why your xfce4-terminal does not pass C-SPC through as C-@. C-h c Describe key (or click or menu item): C-spacebar C-@ runs the command set-mark-command Therefore I conclude that your xfce4-terminal should be doing the same but does not. There are many ways things might fail and therefore hard to immediately diagnose why it isn't working. I would try another terminal emulator and see if it functions better. I would try looking at xmodmap to see if you have a customization that is remapping the keyboard. I would try xev to verify that control is sending Control_L and that spacebar is sending a "space". I would see if there is an XFCE customization that might be affecting things. I might try temporarily creating a pristine new user "guest42" or some such and log in there just to verify the behavior with a pristine new environment. If it works there then you have confirmed that the problem is in your normal environment somewhere. You can delete the temporary user account after you have completed testing with it. I am sure there are many ways to debug this problem. Bob
