unity and gnome session crashed suddenly : I went back to login

[Philippe Breucker]

For several times now, unity crashed with different actions, seems to be randomly : the crash causes the gnome session to end, and all applications with it : I'm back to the login screen...

This bug also affected me.

When working with Gnome 3 or Unity, gnome-session crashes randomly.
I am able to work only with Unity 2D.

Any news about this? Please, I can't use Unity 3D because this. At any time my session is closed and ALL MY WORK IS LOST. I'm using now Unity 2D, and I tried other shells, but I really like Unity 3D. I always used Unity 3D (and Gnome2 + Compiz in the past) wihtout ANY issues in this machine.
How can I help with this?

[Ioram Gordadze (yoh0xff)]

I am waiting for fix also (((
I like very much unity, but can't use it.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately there is not information related to the crash attached to this bug. If it happens again, please click through the dialogs and ensure the crash data is sent to launchpad in future.

[Daniel van Vugt (vanvugt)]

Though if you're using the nvidia driver then this is probably a duplicate of bug 982485.

[Philippe Breucker (breucker-ifris)]

I'm sorry, I don't know how to "click through the dialogs" because there's none : my unity session just crashed without warning and I'm back to the login screen. Could you help me transfer some informations (maybe some logs ?) ?

[Pablo Lillia (gorlok)]

I'm using fix from https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/982485/comments/171
Second day without a session crash. Seems to be related to bug #982485.
Still testing. Cross your fingers! ;-)

[Pablo Lillia (gorlok)]

F*ck! Still crashing. After a few hours, my Unity 3D session crashed (or closed) again and send me back to login screen.
I was using Firefox 13.0 only this time, 4 tabs open. I was watching a youtube video on a tab when it crash, and I had two others tabs with youtube video too.
Except for this, Unity 3D seems to works great in this machine, but I can't use it for work, 'cause I can't risk to lost work.
In the past, I never had have issues with Compiz (Gnome 2) nor Unity 3D with this machine :(
