An error occurred while attaching the driver to ubuntu 12.10. Recovering the Ubuntu 12.10 Unity image has been released today. I downloaded and installed it as soon as possible, there is an additional driver in the "software source" of "system settings". I chose the first navidia-current. After the update, the system will have a logon interface, after login, there is nothing on the desktop and there is no Dash menu, but some shortcut keys can still be used. For example: Ctrl + Alt + t www.2cto.com solution: Press Ctrl + Alt + t to start the terminal and run the command: sudo apt-get autoremove nvidia-current and then restart sudo reboot.
