I'm replying here only because Alberts may be able to give some guidance. Obviously new bug reports need to be filed along with the appropriate info/logs.
I've personally seen three different complaints regarding flashback /gnome-panel problems after release upgrades to Trusty on the forums. I can only find two of those now: http://ubuntuforums.org/showthread.php?t=2220264&page=4&p=13087936#post13087936 http://ubuntuforums.org/showthread.php?t=2239208 They all had in common that gnome-panel no longer automatically launched after boot following the upgrade, I think that should be the primary focus in trying to narrow this down. I realize that the ability to edit the menus is also effected but we have to start somewhere. Cecil's comment above is in relation to the latter of those two forum links. I tried a Precise -> Trusty upgrade earlier today and was unable to reproduce the problem so I really don't know what else to do. @ Cecil, Possibly file a new bug report from the effected system using "ubuntu- bug gnome-panel" titled something like "gnome-panel fails to launch after Precise -> Trusty upgrade", and also attach the logs in /var/log /dist-upgrade. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-panel in Ubuntu. https://bugs.launchpad.net/bugs/1267787 Title: Menus in gnome-session-flashback are bloated in Trusty Status in Desktop panel for GNOME: New Status in “gnome-panel” package in Ubuntu: Fix Released Bug description: Beginning with Saucy I assume that gnome-session-flashback tried to follow the new GNOME Classic Applications Menu extension but it really only resulted in bloat within the flashback menu. I fail to see any benefit to this change. To explain in greater detail, the sub-menu "Other" was added beginning with Quantal to display shopping lenses and later to also display web- apps which is arguably fine. I personally have no problem with that. But in Saucy it appears an effort was made to copy the appearance of the GNOME Classic "Applications Menu" extension. In so doing the following sub-menus were added to 'gnome-panel': (1) System Settings tree view added, but certainly not needed since System Settings also appears in System Tools as well as under the username. (2) Sundry added, but sparsely populated. Orca Screen Reader moved to Sundry from Universal Access, but Onboard is still in Universal Access (being legally blind myself I refer to such changes as rearranging the furniture while I'm not home). Main Menu was also moved from System Tools > Preferences to Sundry which makes it a bit more difficult to eliminate Sundry if one so wishes. (3) Utilities added, but also not really needed as all it accomplishes is relocating a large number of apps from Accessories and System Tools to a new location. Again just rearranging furniture. In summary I'd add that 'gnome-session-flashback' need not mimic the new GNOME Classic session nor vice versa. Two potential fixes, one upstream and the other at the Ubuntu level, have already been proposed here: https://mail.gnome.org/archives/gnome-flashback- list/2014-January/msg00011.html ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: gnome-session-flashback 1:3.8.0-1ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-1.16-generic 3.13.0-rc7 Uname: Linux 3.13.0-1-generic i686 ApportVersion: 2.12.7-0ubuntu6 Architecture: i386 CurrentDesktop: GNOME Date: Fri Jan 10 04:29:21 2014 GsettingsChanges: InstallationDate: Installed on 2013-10-29 (72 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release i386 (20131021.1) PackageArchitecture: all SourcePackage: gnome-panel UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-panel/+bug/1267787/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
