CTRL+SPACE doesn't work in Eclipse

Question

I checked the Keys in Eclipse, Shortcuts in Settings, Autokey doesn't seem to interfere, I'm not sure where else to look for.

How can I trace and fix Ctrl+Space for eclipse?

Solution

This can be caused by a number of different things.

For one, you might consider creating a new workspace and copy the old files into the new one. This has worked for others. Just remember to check the “Copy projects into workspace” when you import.

Another cause could be a wrong configuration in Eclipse. Go to
Preferences --> Java --> Editor --> Content Assist --> Advanced. Here you have to make sure “Other Java Proposals” is ticked.

It could also very well be another applications using the same shortcut which are conflicting with Eclipse. There are no such applications installed by default on Ubuntu though, but it you are using apps such as GNOME-DO (which I believe uses Ctrl + Space) that might be your problem.

Auto-completion (Content Assist), I've also tried enabling and disabling all kind of stuff in the settings section for CA, I think CTRL+Space not making CA pop up doesn't have to do with it's settings.
