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
Preferences only shows the General page and I can't select any other option.
Is there a solution for this problem?
