I downloaded Eclipse from Eclipse page and extracted it in Downloads directory. When I run Eclipse as normal user then application behaves strange:

$ ./eclipse
Gtk-Message: Failed to load module "canberra-gtk-module"

Some symptoms:

  • Eclipse can't resolve symbols in source code and marks them as invalid
  • GUI looks like in other KDE applications
  • when I quit program, then there is some error about write protection

Error message:

Problems occurred while trying to save the state of the workbench.
Could not write metadata for '/ab'.
/home/user/workspace/.metadata/.plugins/org.eclipse.core.resources/.projects/ab/.markers (Permission denied)

I encountered some other problems like write problems during update.

However when I run Eclipse as super user:

$ sudo ./eclipse

then everything works as it should and GUI looks different (GTK is loaded or what? I don't know).

I tried to give 777 permission to all files in Eclipse directory but it didn't work. And I didn't install Eclipse anywhere, just downloaded and extracted. I tried also to download Eclipse with apt-get but there was the same problem. How to make Eclipse work correct?

I use Kubuntu 11.10.

Possibly the permissions on your workspace are messed up? Usually that's in ~/workspaces, so if you do a chown -R on that tree, it might help.

I think that you should use gksudo (kdesudo on Kubuntu) to run graphical applications.
