So , yesterday I was playing some cs go with the open source graphics, but my fps were too damn low , with a ati 270x (approximately 40-50 with breaks), so I decided to install the fgrlx drivers to see if the gains in fps were significantly high. The install process went well , so I decided to restart, and then it happened : I got the login loop problem... And to get things worst, when I press ctrl +alt+f1, a black screens appears and not the terminal, and I can't really do the command sudo apt-get install linux-generic , that seems to be the solution within all the threads referring to the login loop bug . I'm running Ubuntu on a dual boot system with Windows 8.1 and dual monitor system. If all the solutions fail , can someone link me a guide or a quick ELI5 how to reinstall ubuntu on a dual boot machine ?

Any help is appreciated. Thanks,

NEWS/EDIT: after going to recovery mode and unnistaling xserver-xorg and fglrx ,Ubuntu is finally running with updated kernel and Open source graphics, Dual monitors also works fine now. No errors no nothing , all back to normal . Solution was to completely remove all drivers(open and proprietary) and install them again.

You can remove these drivers by

  1. booting into recovery mode and

  2. running

    sudo apt-get purge fglrx*

So i did it i guess but i have a little problem . Going into recovery mode in the GRUB , and root prompt shell doing apt-get purge fglrx -y alow me to enter again and no more login loop. But i have a dual monitor system , and now the system only detetecs one , and reproduces the same image to the both .

Edit: so my drivers where bad unnistalled , and after doing `sudo apt-get install purge fglrx*´ i now cant login to ubuntu at all , just a screen with the original color of ubuntu appears. Damn.
