I installed GNOME Flashback earlier today because I prefer the old interface. While surfing the web earlier, gnome-panel crashed. I thought it would be no big deal, but it didn't come back like I expected, so I rebooted. Ever since, I have been unable to get it to launch. I can access Unity fine (posting from Unity right now), but both Metacity and Compiz GNOME Flashback sessions log in, show my wallpaper, and my start-up apps load, but no gnome-panel.

I've uninstalled and re-installed gnome-session-flashback (purged on uninstall), no luck. Yes, I even tried turning it off and on again (sorry, had to throw that in there).

/var/log/syslog says that gnome-panel.desktop was killed with signal 6, and ~/.xsession-errors shows that indicator-application main process ended (2x) and then says it stopped trying to respawn it.

Has anyone seen this issue, and if so, is there a solution? Thanks in advance!

  • Sounds like a bug, which should be reported at launchpad.net. – mikewhatever May 24 '14 at 7:22
  • Yeah, I figured I'd check here before I did that just to make sure I wasn't being an idiot and missing something. I'll file one tonight or tomorrow after I try troubleshooting while actually awake... Troubleshooting at 2 AM isn't always very productive. – Andrew May 24 '14 at 22:18

EDIT: I broke it again (about 5-10 mins after posting my original answer below)... then I fixed it! Turns out, when I was adding a new app to the Applications menu in flashback using alacarte it happened again, so I went to kill all my .desktop files, and as it turns out I somehow corrupted something in ~/.config/menus.

Specifically, I added an entry to the Internet category, and it created a duplicate Internet entry, and when trying to hide that, gnome-panel crashed.

Let's see if I can do what I want without breaking things...

After taking some more time to troubleshoot the issue, I've found that it's something specific to my user account. I tried logging in as a guest with gnome-flashback (as I should have done originally) and it worked!

I tried clearing all my Unity, Metacity, Gnome, and Compiz settings with no luck. I tried reinstaling flashback, compiz, and making sure everything was up to date. None of these helped. I can only suspect that a file got corrupted somehow in a settings file I didn't know to reset.

Seeing as I'm more familiar with Ubuntu Server than I am desktop, I decided to backup my home directory, delete my user account, and re-create it and restore my documents, music, etc. from the backup.

So far so good. It's working like a charm now. Will it happen again? Maybe (more likely than not with my luck), but hopefully not.
