I've just upgrade my Ubuntu from 9.04 to 9.10 and I'm experimenting a very annoying problem with Eclipse Galileo.
The problem is that Eclipse doesn't catch some button clicks. For example, I've tried to install a plugin and I clicked on next, and then nothing happened.
I didn't have the same problem before the upgrade of my Ubuntu version.
This is a known bug (bug 291257) with Eclipse 3.5 and GTK+ 2.8 (fixed in Eclipse 3.6). The workaround is to set the GDK_NATIVE_WINDOWS environment variable to true before to start Eclipse.
I use the following startup script for Eclipse:
#!/bin/sh export MOZILLA_FIVE_HOME=/usr/lib/mozilla/ export ECLIPSE_HOME=/opt/IBM/eclipse export GDK_NATIVE_WINDOWS=true # workaround for Karmic - http://bit.ly/T8MIc $ECLIPSE_HOME/eclipse $*
The important part is the line export GDK_NATIVE_WINDOWS=true.
There was a change in GTK with Karmic. Here are the relevant bugs:
