Question: I run Ubuntu 12.04.4 LTS 32 bit version and recently took the option to take the HWE upgrade from Update Manager. Now either the computer freezes or I go into a low graphic mode similar to the Terminal. I believe this is because I have an old Nvidia FX5600 graphic card. If I run 3.13.0-32-generic in recovery mode I can use my computer. My question is can I reverse out the HWE upgrade or will I have to reinstall the OS from scratch using the original CD?

Answer: 
*NB: This does not answer your question but rather tells you how to fix your problem while still using the new HWE.* 

Open a terminal (hold in `CTRL` and `ALT` while pressing `T`)
Add xorg-edgers PPA and update

```
sudo add-apt-repository ppa:xorg-edgers/ppa

```

You'll have to supply your password when prompted. You'll get all sorts of info about this repo but to continue just press `ENTER`

Now in the same terminal:

```
sudo add-get update
sudo apt-get install nvidia-304

```

You need to press `Y` + `ENTER` for it to be installed. 

When it's finifshed you restart your system. To confirm that you are indeed using Nvidia drivers you may open **System settings** in the menu on top right and choose **Additional Drivers** from the Hardware section. It takes some time for it to start up but when it's there it will tell you if you are using Nvidia driver. It might be that you could in fact activate your driver from this view after `sudo add-get update` but I didn't do that so I'm not 100% sure. Before the HWE update I had several choices here but now I only have the one I have installed.

There is a [bug report on this issue](https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304-updates/+bug/1345217) and it can happen this problem will be solved upstream. To stop using the PPA:

```
sudo rm /etc/apt/sources.list.d/xorg-edgers-ppa-precise.list
sudo apt-get update
sudo apt-get install --reinstall nvidia-304 

```
I had the same issue: after upgrade I could only boot into the tty screen. After trying numerous fixes, I happened to notice that the Nvidia kernel was using driver 173, while the rest of the conf was 304. The only solution was to disable 304 and enable 173 using jockey-text:

```
sudo jockey-text -e xorg:Nvidia_173

```

now working as before.
