I'm worinkg on a lenovo Y560 notebook with dual (intel &radeon hd5470) graphic cards. Everything was working well, till i tried to install ati catalyst. Since then my GUI failed. However, I managed to manually change current drivers in xorg.conf from 'fglrx' to 'intel'. Now everything is working, but my gnome boots into Fallback mode. Silly of me, I haven't made a backup copy of previous settings. Is there any way I can return to my old drivers, whici afaik was Intel Ironlake Mobile?
