when i had the same problem again i switched to the terminal Ctrl+Alt+F1 and did a jstack process dump.
i am not sure how to read the output but it seams to me that most processes are in a deadlock waiting for an org.eclipse.swt.internal.gtk.OS.Call to finish. process dump is attatched ** Attachment added: "jstack process dump" https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/894470/+attachment/2851732/+files/eclipse.stack.deadlock -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-6 in Ubuntu. https://bugs.launchpad.net/bugs/894470 Title: eclipse36 hangs, keyboard disabled EXCEPT for the SUPER key, mouse movable but no clicks processed Status in “openjdk-6” package in Ubuntu: Confirmed Bug description: I have an old (German) (Windows) PS-2 keyboard. My oneiric is a fresh install, but I have restored a lot of my data files (and some config files in /etc) from a backup which was from an older oneiric, upgraded from natty. When I work with eclipse36 for a while in oneiric under unity, eclipse 36 helios (from 2010) suddenly hangs. Then, all keys on my keyboard are disabled EXCEPT for the SUPER (Windows) key. When I press it, the Dash shows up and gets the focus. When I press SUPER again, eclipse gets the focus (the frame-colors of some panel in the IDE briefly flashes) The mouse is movable but no clicks are getting processed. Ctrl Alt-F2 does not work. Removing the keyboard and plugging it back in does not work. I have to go to another computer, login to the hanging computer with ssh (works fine), then kill eclipse. Then, mouse and keyboard are usable again. Besides, and maybe unrelated to the above-mentioned- bug, sometimes eclipse crashes. There is no Eclipse crash dialog box with process metadata.
