- Boot into recovery mode
- Remount read/write
Enter root shell
Go to the location where you downloaded the installer then: ./ati* --uninstall
Reboot:)
But, you can also get the drivers working by following the steps above, then follow steps 1 to 3 again and replace step 4 with: ./ati* --install
.
Then type: aticonfig --initial
Then reboot.
This is how I got the latest drivers from ati working.
I started with a clean 12.10 install (not an upgrade)
My card is a Radeon HD 5450
First thing I done was to install Linux-source and Linux headers
sudo apt-get install linux-source
sudo apt-get install linux-headers-generic
I noticed that many with Nvidia cards were having to do this and am sure I saw mentioned some-where that it also helped ATI users.
Like everyone else if I installed either of the proprietary drivers after reboot I was able to login but lost unity.
One thing I did notice is that installing the driver did not install Catalyst control centre (not sure if it is the same for everyone else)
So I installed Synaptic package manager and installed fglrx-updates from there

Now the Catalyst control centre was installed.
Upon rebooting however instead of being able to login with no Unity the system was hanging at the splash screen.
So I applied nomodeset
and this time it booted with Unity present
Here is the result of fglrxinfo

And here is what software sources says

With nomodeset
applied I might not be getting the splash screen on boot up but fglrx-updates is working well. I would go as far as to say that it is performing better than it was in 12.04
More info
Grub offers me 2 kernels
3.5.0-18-generic
and
3.5.0-17-generic
The later one '18' is good, the older one '17' still loads without Unity

I'm not sure this is the correct answer, but I'll have a go. Try this page. Extracted instructions:
followed by the following for the sake of making sure all is clean:
That should remove all previous FGLRX drivers you had. Now you're back to the fresh Ubuntu graphics setup. This question provides an answer on how to get FGLRX working with Kaveri, but you had already seen that question.
