I am running an ubuntu/gnome3 environment. While running the upgrade manager on 12.04, I was informed that there was a distribution update but that it was partial. (whatever that means)

After a few failed attempts at updating through the manager, I decide to run sudo apt-get update && sudo apt-get update. The updates seem to work however, the close/maximize/minimize buttons of all windows have disappeared. I also can no longer use the Alt+Tab function.

I tried to post an image but I need more rep (sorry)

I have tried to run the updates again but nothing changes. I'm still very new at this. I would appreciate it if you could use simple terms to describe or ask questions.

Thanks in advance!

Welcome to Ask Ubuntu! This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions on filing a bug report are here. – Jorge Castro Oct 4 '12 at 23:39
@JorgeCastro: it seems to me that whether it is a bug or not, his first objective is to fix the problem so he can get back to work in a normal manner. Aren't we here to help with that, or do we just chastise him and make him wait for help elsewhere? – Marty Fried Oct 5 '12 at 0:56
Did you lose the entire titlebar, or just the buttons? If just the buttons, try changing themes, then change back to see it that will fix it. – Marty Fried Oct 5 '12 at 0:57
It looks like the buttons have been replaced by "File, Edit, View, go, bookmarks and help drop down menus. – Marc Sauvageau Oct 5 '12 at 3:33
Thanks Jorge, I'll keep that in mind from now on. – Marc Sauvageau Oct 5 '12 at 3:34

I can think of 2 tools that might help you: GNOME Tweak Tool and gconf-editor.

Both are available for free in the Software Center, and once their installed, you can open them by Alt-F2 and then typing their names.

GNOME Tweak Tool is the simplest one to use.

In gconf-editor, the settings for the close, maximize, minimize buttons are under:

apps → metacity → general

I can't guarantee this will help, but it might at least point you to the right direction.

Thanks for responding Alex. I've tried changing themes in Gnome-Tweak-Tool. The themes change but the buttons don't come back. I've looked at gconf-editor and the settings are correct "button_layout close,minimize,maximize:" I'll read-up on how to report bugs since you can't ask questions on askubuntu (who knew?) but any other advise would be greatly appreciated. – Marc Sauvageau Oct 5 '12 at 4:07
