problem with gnome 3 shell

[jackal_79]

iam using ubuntu 11.10 with gnome 3 shell.It was working fine from more than a month until today.The problem is like this:
It boots up fine.Iam able to open applications by pressing windows key.After i open any application the top bar disappears.If i open a browser it does not open in maximized mode and if i try to maximize either it shuts down or nothing happens.Now, after i open any app iam unable to use the windows key any more and even alt + tab of alt f2 doesn't work.i have to press ctrl + alt + f1 and reset lightgdm.And then the process continues.Now iam using gnome classic and it is working fine.
Someone please suggest how to make gnome 3 work again.

have you checked "looking glass" to see if you are getting any shell errors? if not try Alt-F2 and enter the command lg and check the errors tab

As i said earlier once the top panel disappears i won't be able to use alt + tab , Windows key as well as alt f2 also.

Post up a list of your extensions. I'm getting the same problem from time to time. Perhaps we can track down where the issue stems from. Here's mine.

If there's one or more in common, it could be an issue with the extension. This happens to me when my screen blanks (even though I have it set to never shut off in screen settings).

log in with a different shell, like unity, and turn off all the extensions, then you can turn them on one at a time to see which is causing you issues

Can't turn off extensions from another desktop environment. You'll have to delete the from /usr/share/gnome-shell/extensions/ or ~/.local/share/gnome-shell/extensions/.

True not the way I said to do it, but if you log in with a different shell, you can use dconf-editor you can edit the list of extensions under org.gnome.shell.enabled-extensions. Then you can try turning them on again one at a time
