Hello, I’m using laptop ASUS A42JC with VGA NVIDIA optimist that can be switched to on board if the add on VGA is not needed. I have dual boot operating system with Windows 7 and unbent 10.10 Maverick installed in the laptop. I have no problem with the VGA with Windows 7 but the real problem lies in unbent. I have installed all the needed drivers but the only driver not installed yet is the VGA driver. I have received recommendation from unbent. So I did install them, and as usual after installation completed I restarted the laptop. After restarted, I cannot use unbent GUI only can access terminal. I'm confused I thought I installed the recommended driver for the VGA but why did it fail?
Installed the recommended driver for the VGA

To fix this error you should install linux_headers_generic.aftre that revert the nouveau.
Now open terminal(ctrl+alt+T) and type the following.
  nvidia-current (proprietary,tested):
sudo dpkg-reconfigure nvidia-current.
nvidia-current-updates (proprietary):
                               sudo dpkg-reconfigure nvidia-current-updates.
nvidia-experimental-304 (proprietary):
                               udo dpkg-reconfigure nvidia-experimental-304.
Now reboot the pc and all will be working again.

Hi,Â
Use this code in the terminalÂ
audo dpkg-reconfigure -phigh xserver-xorg
If still you are unable to log into the GUI you need to remove the VGA driver. For that run this code in the terminal:Â
audo apt-get purge nvidia*Â
audo dpkg-reconfigure -phigh xserver-xorg
And if possible, replace the nvidia card with an AMD cardÂ
