ctrl+shift+u is a combined shortcut key in Eclipse.

But when I press it, it shows up a u, just like input with an underline. I guess this shortcut has been declared by Ubuntu, so I can't use it.

I used to solve this problem by typing capslock first. Is there any better method?

Are you asking how to disable the ubuntu short-cut? In KDE there is a global configuration screen in which you can edit 'global shortcuts'.. There is an equivalent in gnome. Find and shut off ALL shortcuts you don't think you'd use (which would be most of them).. Why they don't just use the windows button for window-manager shortcuts I'll never understand.. Eclipse and friends are in horrible conflict with the wims of these windows-wannabies.

I think it's gconf-editor or similar. –  Rob Nov 18 '11 at 14:16
Maybe, but this is not helpful at all. –  MariuszS Aug 22 '13 at 17:18

Found a way to unbind it on Ubuntu 13.10.

Go to Language Support on System Settings and change the Keyboard input method system to none

Then restart the system.

Open a terminal window.

cd ~/.gconf/desktop/gnome/interface
gedit %gconf.xml

Change the show_unicode_menu from true to false.

Save, Log out and back in.

/desktop/gnome/interface/show_unicode_menu is already disabled (false) Question is about keyboard shorcut, not menu. –  MariuszS Aug 22 '13 at 17:15
good use of time, downvoting an answer almost two years old. –  John Barry Aug 22 '13 at 18:42
Two years later this question is still valid... so why not? –  MariuszS Aug 23 '13 at 12:13
