Ubuntu 16.04 and Eclipse Mars menu problem

Question

My OS is Ubuntu 16.04. I downloaded Eclipse Version: Mars.2 Release (4.5.2) and I had a problem with the main menu not showing.
I solved it by running Eclipse with UBUNTU_MENUPROXY=0 and the menu is visible but now I have another problem. Some of the options in the menu don't work.
For example the Window->Preferences only shows the General page and I can't select any other option.

Is there a solution for this problem?

Solution

Try to start Eclipse after editing your eclipse.ini file and tweaking the launcher entry like this:

--launcher.GTK_version
2

Example file:

-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.GTK_version
2
-product
org.eclipse.epp.package.cpp.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.7
-XX:MaxPermSize=256m
-Xms256m
-Xmx1024m

Your UBUNTU_MENUPROXY=0 tip fixed my problem! I added env UBUNTU_MENUPROXY=0 /.../eclipse to my shortcut.

This didn't work for me. It actually made the problem even worse.

Worked with Eclipse Neon.2 for J2EE on Xubuntu 16.04.
