Upgrade from 12.04 -> 12.10. No window manager.

[Nic]

I just upgraded from 12.04 to 12.10 via the update manager. Everything went smoothly untill reboot. After reboot, I have no window manager, and no unity interface (I don't know if they're the same thing). To be explicit: I have no bar at the top of the screen (with usual network connections and clock/calendar etc.), and no bar on the left with the Dash and my apps.

I can start the terminal using keyboard shortcuts, and then firefox from the terminal, which is how I'm writing this report.

There were some general error boxes that came up, but I forgot to screencap them. One of them was about Compiz, which I think might have something to do with window management.

I don't really know how to fix this, can someone contact me with advice? I'd rather not reinstall everything.

Sorry, I wasn't a hundred percent clear: on top of having no bars on top and left, I have no "close" "minimise" and "maximize" buttons on my applications. These are functions that I believe are associated with the window manager, which is why I mention it.

I had the same problem.
it ended up being a problem with the nvidia driver (I have nvidia Geforce GT 540M)

solved it by install bumblebee:

sud apt-get remove nvidia-current
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia

hope it works for you as well

[Nic (nic-rss)]

Yes, thank you, that has fixed the main problem (window manager and unity interface).

NB however that I couldnt get bumblebee from the rep that you quoted, but rather the one quoted on their website.

[Tzafrir (tzaf)]

sorry.
i forgot to copy that command
first you should run
sudo add-apt-repository ppa:bumblebee/stable
as stated on their website

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem. But I have an ATI card, not NVidia.

[Kevin Wortman (kwortman)]

It turns out my problem is that I have a Radeon 3000 series video card. It's only 2 years old but apparently has been deemed "legacy" and is no longer supported by official packages. The instructions here solved my problem:

This seems like something I should've been warned about during the install, or that should at least be mentioned in the Release Notes.

The solution listed by tzaf fixed this problem for me. Thanks.

I have solved it by installing nouveau drivers and running in classical gnome window manager. Possible problem was most likely my dual screen configuration.
