fglrx 2:13.350.1-0ubuntu2: fglrx kernel module failed to build

After changing the driver to privative, my system crushed. Couldn't boot neither console or graphics.
I made a lot of changes through onsole. Update , upgrade , delete propietary devices , install lubuntu , cleared my password, etc.
I don't know what has happen that now it seems to be working well. Hope it continues like this
