Ubuntu 13.04 Nvidia Optimus, Unity crashed

Question

linux

Guys, Unity crashed (as far as I can tell). After installing the video driver from Nvidia (NVIDIA-Linux-x86_64-319.23), the side and top panels disappeared, Alt + Tab stopped working.

None of the actions led to the return of the desired. Tried: uninstall, reinstall, reboot (3 times).

What can you advise? :)

Decision:

sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

sudo apt-get install --reinstall unity
sudo apt-get install --reinstall ubuntu-desktop

sudo reboot
