application menu disappeared and the main menu item has no response
 

If you still need help for this problem, try right clicking on the 'applications' menu and choose 'edit menu'. Then you can just check the items you want. If that doesn't work, then click system > preferences > main menu, and you can add things to your menu that way. If that doesn't work, then try right clicking on the yop panel and choose 'Delete this panel'. Then right click on the bottom panel and choose 'New Panel' and put the new panel at the top of the screen where the old one was. Then right click on the new top panel and select 'Add to Panel'. Then select "Menu Bar" from the list. This will give you a brand new menu bar like the old one. Then just right click on that and edit it to your needs.

In fact, the problem goes with me all these days, and I need help badly. But the methods you mention above don't work for me.
Neither the 'edit menu' nor the 'system>preferences>main menu' works. They just make no response! And the brand new menu bar has the same problem as the old one. I don't know how it come. Have I deleted some necessary packages?

Some googleing suggests that resetting your gnome settings might fix your problem. See this:
http://linuxfud.wordpress.com/2007/0...re-installing/
What I would do is to move those gnome directories in your home directory to a backup instead of deleting them.
Then log out of your desktop (ctrl + alt + back-space) and log back in; or just reboot, and see if it fixes things. Those directories you moved to *.bak will be recreated when you log back in.

If that doesn't work, then delete those directories (.gnome, .gnome2, .gconf, .gconfd, .metacity). Then reinstall gnome:
.
If that doesn't fix it I'm out of ideas. Reinstalling the ubuntu desktop should fix it, provided you delete the user settings in the above mentioned directories first.

I delete the above directories and reboot. Then every thing seems to be reseted to the default: the background, the icon theme, the shortcuts ....except one thing: The items in "applications" menu are still missing!
I won't take any further effort now. I just sit and wait the coming intrepid ibex bring me back to life.

Thank you all the same.

How do you guys know this stuff????? I'm persevering with Ubuntu (9:04) and find most things really great BUT when things just disappear without me doing anything - well, I think I did nothing! - I begin to wonder how other people will ever move from MS to a Linux Distro.

Anyway, thanks for your help, even though you didn't know I was in trouble!

Perhaps someone here can help… I have deliberately not “upgraded” from 11.04 to 11.10 just so I can keep the Gnome 2 “Ubuntu Classic” desktop which I very much prefer. Sadly, I was trying to alter the Startup Applications to allow Knemo to start on login, when my system froze for some reason, requiring a hard reboot. Upon restart, I find have lost my Applications menu entirely, and the System -> Preferences menu, and the System -> Administrator menu have disappeared too.
!!!!!!!!
I must have tried the various resets that abound on the forums, to no avail.
The last thing I want to have to do is a full reinstall, which would fix it, of course, but it would kill all the customisations which one inevitably makes.

Any ideas on how I can remedy this situation? There must be some default listing that I can reinstall, or go back to. It exists somewhere on the install disk, so it must surely be resetable.

A full-reset switch is certainly something which is missing from the desktop environment, but that is a topic for another discussion.

Anyway, please help!

Thanks in advance

thx on answers

OK... I managed to fix my problem by way of:
"mv ~/.config/menus/applications.menu ~/.config/menus/applications.menu.bak"
and
"mv ~/.config/menus/settings.menu ~/.config/menus/settings.menu.bak"

Log out, login... all fixed!

I have only to add my top panel customisations again, and things are (hopefully) back to normal.
