Ubuntu 16 LTS - Eclipse window preferences not working properly

Question

I\'ve just installed Ubuntu 16.04 LTS. I downloaded a fresh Eclipse on March 2 for Linux 64-bit.

I am using the latest Oracle hotspot JDK 1.8 update 91 release.

Answer 1

put the 2 lines in italics below into eclipse.ini:

--launcher.GTK_version 2

before the line:

--launcher.appendVmargs

Answer 2

The issue is the updated GTK version.

The following post solves the problem: https://askubuntu.com/questions/761604/eclipse-not-working-in-16-04

Setting the following into eclipse.ini

--launcher.GTK_version
2

As explained in the ubuntu Q&A.

Answer 3

I had problem starting Eclipse using left side Launcher - got problems with preferences.

When I launch eclipse from its directory by double clicking "eclipse" or when using Terminal to launch eclipse, then it WORKS.
