How to turn off proprietary ATI drivers using Recovery Mode?

I have setup just like in this question - AMD A10-7850K APU and an Asus A88XM-PLUS motherboard. Instruction by Ruben Bakker tells me how to install what I need, but it does not tell me how to clean up my system after a failed attempt made on my own.

I installed drivers using Additional Drivers manager. Restarted, and now every time I boot all I can get is a black screen. Keyboard and mouse are trapped and I can't switch to text console, and so on. I can boot to recovery mode but what do I do there? In the old times when I was using Gentoo I would just edit xorg.conf to switch to an open driver, but I can't find anything like that in my Ubuntu. And I'm sure there is no text-based version of Additional Drivers manager.

I'm not sure this is the correct answer, but I'll have a go. Try this page. Extracted instructions:

sudo sh /usr/share/ati/fglrx-uninstall.sh

sudo apt-get remove --purge fglrx*

followed by the following for the sake of making sure all is clean:

sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon

sudo apt-get install xserver-xorg-video-ati

sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

sudo rm -f /etc/ati

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.
