14.04 login loop after cuda installation

I've installed cuda 7 on my 64bit ubuntu 14.04 using this guide. After disabling nouveau drivers following this and rebooting, I needed to disable graphics with Ctrl+Alt+F1, login, and then stop lightdm


sudo stop lightdm

then ran the installer .run file. Installation finished successfully. After installation finished I rebooted with:


sudo  reboot

But after the reboot when I tried to login, the login page reappeared. I have tried almost all the solutions suggested here but nothing changes. More specifically I've tried correcting ownership of .Xauthority, .ICEauthority, and .gvfs. I've tried removing .Xauthority and /tmp. I've tried reconfiguring lightdm with:


dpkg-reconfigure lightdm

and also tried removing and restarting lightdm. But nonof them has worked. What should I do?
