Very large tabs in Eclipse panes on Ubuntu

Question

My question is very similar to Stack Overflow question Gigantic Tabs in Eclipse on Ubuntu.

I have tried the solutions presented, but they appear to be old.

Answer 1

Eclipse is now (4.5 Mars) defaulting to GTK3 on Linux. For 4.6 a fix seems to be alredy merged.

Changing SWT_GTK3 environment variable works for Eclipse Mars:

$ export SWT_GTK3=0

or set that variable inline with running eclipse

$ SWT_GTK3=0 /path/to/eclipse/eclipse

To kill it dead just drop this in the root as eclipse.sh:

#!/bin/bash
SWT_GTK3=0 exec env "${0%.sh}"
