I was using Eclipse and it disappeared. I can see its running using ps command, but I cannot Alt-Tab (Switch) to it, and its missing on left bar.
Before restarting it (I will loose work :S) does anybody have a suggestion? (Even switching to running "hidden" process in another way than unity)
Thanks!
Are you sure you didn't accidentally moved it to another workspace? You can use the key combination Super (Windows logo key) + S to view all of your workspaces at once.
Maybe you can --reset Unity and see if that's gonna help, but I wouldn't bet on it: http://manpages.ubuntu.com/manpages/precise/man1/unity.1.html
Good luck! Hope it helps. :)
