After installing elementary OS Freya x64 I updated it and installed AMD graphics drivers. After rebooting everything worked fine, but later I installed some programs and now Freya freezes on loading screen everytime I try to boot.
When I press ctrl+alt+f1
there is no error message and when I press f2
I see some system messages, but eventually it stops and then nothing happens. There doesn't seem to be any error and it doesn't always stop at exactly the same point but it's always after "System V runlevel compatibility".
I can only go to recovery mode and drop to root shell, but I don't know what to do there to fix my system. Could it be something wrong with AMD drivers? Please help.
