Ubuntu - shortcut Ctrl + Space causes conflict in eclipse [closed]

After I updated ubuntu a new keyboard shortcut appears:

CTRL + SPACE

And I use that shortcut in eclipse to complete commands, and is very practical.

Rather than complete the command appears to me a window to switch the keyboard layout (pt_br Brasil or en_us USA). My keyboard layout uses the Brazilian and I do not want to change.

But I want to know if you have to change this shortcut to not give more conflict with eclipse. Can someone help me?


Open System Settings and go to "Text Entry" change the keys under "Switch to next source using:" to some other keys.
