[Yifan Yang <yfyang.86@xxxxxxxxx>]

The issue happens when I installed any private nvidia driver on 14.04
with my NV-550 Ti card on every kernel version (up to 3.13.0-46). As I
have *dual screen* (VGA+DVI), which is another issue which may cause the
failure of the driver.

This is what I've done to fix it, you may need to enter tty mode (ctrl +
alt + F2 for example) and enable web:

```bash
#kill lightdm/kdm/ whatever you X-window is
if [ `ps -ef | grep lightdm | wc -l` -gt 1 ]; then 
    sudo service lightdm stop
    else sudo service kdm stop;
fi

# Install kernel-header
sudo apt-get update
sudo apt-get install linux-generic build-essential

# Get official 346.47
wget http://us.download.nvidia.com/XFree86/Linux-x86_64/346.47/NVIDIA-Linux-x86_64-346.47.run

# enable exec &run
chmod +x  NVIDIA-Linux-x86_64-346.47.run
sudo ./NVIDIA-Linux-x86_64-346.47.run

```

After installation, reconfigure your unity in case your Gnome fails to
load it:

```bash
# reconfig monitors: This is important in my case.
rm ~/.config/monitors.xml 

## install ccsm
sudo apt-get install compizconfig-settings-manager python-compizconfig compiz-fusion-plugins-extra compiz-fusion-bcop compiz-fusion-plugins-main compizconfig-backend-gconf
sudo reboot
```

After reboot, you may probably see the Gnome back again. If not hit
<Ctrl+Alt+F2> and login:

```bash
#kill lightdm/kdm/ whatever you X-window is
if [ `ps -ef | grep lightdm | wc -l` -gt 1 ]; then 
    sudo service lightdm stop
    else sudo service kdm stop;
fi

export DISPLAY=:0.0
ccsm
```
and re-enable unity-plugin when you get back to X using <ctrl+Alt+F7> and configure the display afterwards. You may need to rest the unity and has nothing to do with this thread.

It seems we need to compile the DKMS every time kernel is updated and I
personally use my code to re-enable the private driver.
