I hope I'm not asking a duplicate question, but I've searched through the archives and attempted to do it myself several times.
Several months ago I was attempting to install ATI drivers in an attempt to play Team Fortress. The 'additional drivers' menu didn't work, so installed and reinstalled the drivers manually several times. Eventually I must have messed something up, because I got a black screen of death on boot. Luckily I had made a backup xorg.conf, which I then 'mv'd to xorg.conf and rebooted. However, now I am having all sorts of trouble; due to what I imagine is no hardware acceleration. The entire system is sluggish and unable to run anything that requires sophisticated graphics, include anything with wine. The part that's confusing me is my inability to remove the ati drivers now installed.
when I run
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 153 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)0
Serial number of failed request: 12
Current serial number in output stream: 12
If I run
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*
E: Unable to locate package fglrx_8.970-0ubuntu1_amd64.deb
E: Couldn't find any package by regex 'fglrx_8.970-0ubuntu1_amd64.deb'
E: Unable to locate package fglrx-amdcccle_8.970-0ubuntu1_amd64.deb
E: Couldn't find any package by regex 'fglrx-amdcccle_8.970-0ubuntu1_amd64.deb'
E: Unable to locate package fglrx-dev_8.970-0ubuntu1_amd64.deb
E: Couldn't find any package by regex 'fglrx-dev_8.970-0ubuntu1_amd64.deb'
However, if I pop open xorg.conf in a text editor, it says:
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen-0" 0 0
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
Viewport 0 0
Note that only this xorg.conf works; the other version I have backed up (presumably from when my system was entirely free of this ati garbage) only gives a black screen on startup.
Here is the output of

Please help me figure out how to remove these ati drivers, I implore you. 000
P.S. I forgot to add that reinstalling xorg etc. as per
sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 xserver-xorg-core sudo dpkg-reconfigure xserver-xorg
it gives me a black screen of death on boot, presumably because the ati drivers failed to remove. Thanks again.
