Created attachment 254491 [details] .ini .sh and .log Eclipse is hanging at various stages when I launch. It always gets to the prompt of workspace dialog. After that sometimes it hangs immediately, sometimes it hangs on org...theme, sometimes it hangs on org...swt, sometimes it loads the main workspace window (consuming about 1/3rd x 1/3rd of my screen) and just stays grey, sometimes it loads the workspace window, maximizes, loads the toolbar and nothing else. Always it takes one of my 8 cores to 100%. Afterwards, opening a new window, takes forever. I can switch to email, but I can change to a new email. I can switch to the browser, but I cant switch tabs. I can switch to my terminal, but I cant open a new terminal. Recovery is only by killing the java process at which point I can operate my system normally again. I have tried Kepler, Luna and Mars. Same result. I have tried clearing the workspace/.metadata/.plugins folder I have removed all traces of eclipse and re-installed I have tried installing eclipse for only myself (under my home directory) I have tried openjdk7 and 8 as well as oracle jdk 7 and 8 I have tried adding --launcher.GTK_version 2 to eclipse.ini I have tried launching eclipse using a script with export SWT_GTK3=0 I have tried using NVIDIA drivers and nouveau, no change I have tried the standard adwaita theme as well as other themes I have been running eclipse for quite some time on my desktop (kepler and earier versions) and I run luna on my laptop which is the same OS install, not sure what broke my desktop nor why it still runs on my laptop OS is ubuntu 15.04, Gnome 3.14.4 (and Gnome 3.16)
While Eclipse hangs, please run jps jstack <pid from jps above> commands and attach the stack trace here.
Mars works well for me with Ubuntu 15.04, I use it since the Ubuntu release. I'm not aware of this launcher setting you are using but to enforce GTK2 I use: export swt_gtk3=0 But in general GTK3 works fine for me with the latest I-Build of Eclipse. Can you post your I-Build number? Ctrl+3 -> Copy Build id to Clipboard
Created attachment 254610 [details] jstack trace ok, I have done more testing, sorry it took so long. I upgraded to gnome 3.16 and mars runs with no problems. I did a ppa-purge of gnome3-staging and went back to 3.14 and the hang re-appears. I cant currently stay on 3.16 as there are other issues with 3.16 - there are serious visual defects on my computer using it. Sadly the stack trace probably wont help as it's not a stack trace of eclipse, but rather an error saying the debugger cant attach. Peter
The problem has now appeared on 3.16. I am not sure what changed in the past couple of days. I am now completely unable to run eclipse

I wanted to add just a couple more notes: normally I dont get past the spash screen, it stops at org.eclipse.ltk.ui.refactoring or org.eclipse.jst.j2ee.ui Every now and then it will show the gui but hangs. I'll get an incomplete gui (only top 1/4th of icons are shown, and even though the main container window is maximized, all of the panes, and docks are not in their correct place (they seem to be placed for a smaller window layout). If I then click on the minimize/maximize/close buttons for the main window, it does nothing. Worse it now seems to freeze some event loop for gnome-shell. If I click on activities, or alt-tab, or the overview key (windows key), nothing happens. if I type, nothing happens. Then after killing the java process, all the events that were queued now execute (ie: windows key, type h e l p, hit esc)
Eclipse still works fine for me on Ubuntu 14.04. Can you try the Eclipse SDK from http://download.eclipse.org/eclipse/downloads/ The Java EE plug-ins might be causing that, I have them not installed.
Anything new here? Please reopen if it still does not start for you.
The problem has not manifested itself in a couple of weeks. It is possible that I was suffering from a hardware issue as I replaced my mobo and memory and cpu (normal hardware upgrade) and have not had the problem even once since. However it does reveal another very serious issue, and that is the inability to troubleshoot these types of issues. A "debug" log that is much more instrumented showing each step of the init process. There is a log but it seems to not be detailed enough. The stack trace is nice, but if jstack cant attach it's of no use.
