Revert AMD graphic drivers

Question

I've installed AMD graphic drivers and rebooted my system. Now when i'm logging in my screen turns off or shows a lot of noise in different colors, but i cant see anything. That means i cant use my Xubuntu insalled on HDD. I've live USB Stick, how to revert installation using Live USB? Or maybe nay other possibilities?

@Rmano Is there possibility to log on my HDD Xubuntu from Live USB Stick? — Michał Staniewski, Oct 20 '14 at 16:41
You can boot in console only mode probably even without the USB disk --- follow http://askubuntu.com/questions/162075/my-computer-boots-to-a-black-screen-what-options-do-i-have-to-fix-it booting with options nomodeset single, or boot into recovery mode: http://askubuntu.com/questions/150367/how-do-i-boot-into-recovery-mode — Rmano, Oct 20 '14 at 16:45

Boot your computer.
After it is started, swicth to TTY1 by pressing Ctrl+Alt+F1
Log in using your normal username and password.
run this command to remove the drivers sudo apt-get purge "fglrx.*" "fglrx-amdcccle.*"
run sudo rm /etc/X11/xorg.conf to delete the x.org configuration file.
run sudo apt-get install --reinstall xserver-xorg-core libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:amd64 to re-install x.org.
run sudo dpkg-reconfigure xserver-xorg to reconfigure x.org.
run sudo reboot to reboot.

You can do this from your Xubuntu computer, but you will need to type all these commands in. A lot of this I copy pasted from here: How do I remove the proprietary ATI drivers?

I don't use AMD drivers personally.

Whichever Command in Passing IT says for lock file var/lib/dpkg/lock only for read lock wont be used,couldnt write to /var/cache /apt – Michał Staniewski Oct 20 '14 at 17:11
Make sure you are using sudo when typing in these commands. – Paul Tanzini Oct 20 '14 at 17:28
it automatically makes me a root – Michał Staniewski Oct 20 '14 at 17:30
If you're root then apt-get shouldn't give you that error unless there's something that is already using apt or dpkg. – Paul Tanzini Oct 20 '14 at 17:34
WARNING. sudo apt-get purge fglrx* is wrong. You should use sudo apt-get purge "^fglrx.*", it's a regular expression... see http://askubuntu.com/questions/210976/apt-get-remove-with-wildcard-removed-way-more-than-expected-why – Rmano Oct 20 '14 at 17:35
Found out that i had to mount all devices manually, that was a problem :) Thank you for help – Michał Staniewski Oct 20 '14 at 17:44

@Rmano I changed the regular expression to the one that was given in the older AU question I linked to. – Paul Tanzini Oct 20 '14 at 17:45
