I followed instructions to install nvidia drivers found here: Nvidia driver doesn't work in 12.10 But it doesn't work for me. Same problem like in the question above: no dash and windows don't have borders.

I tried opening nvidia-xsetting, which asked me to run nvidia-xconfig. Running that did nothing but generate a broken xorg.conf which I had to remove because of really low resolution. I thought this is "unity not loading problem" but instead this seems to be "driver not loading problem" because nvidia-xsetting said that I don't use nvidia drivers (which btw I find really weird because lsmod says nvidia kernel module is indeed loaded), and games didn't load either.

I can "fix" this by doing modprobe nouveau, but with nouveau 3D games like 0 A.D. are broken.

Any ideas? I'm out of them.

I solved it. Problem was that nvidia cards for notebooks (I got geforce 635M) require bumblebee:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-headers-generic bumblebee bumblebee-nvidia
sudo reboot

After reboot run your games ( 0ad for example ) like this:

optirun 0ad

Works like charm.
