Today I tried to install the ati/amde proprietary deriver after downloading it from their website. I followed their instruction and the installation was ok , it didn't generate any error while installing. But while trying to reboot I get my login screen but after login I get only a blank screen with the usual desktop background. I am using Ubuntu 13.04.
It'd be great if anybody can help me get back to my old default driver and restore to previous state before installing this driver.
P.S-I am currently using a live usb to boot my computer and access my existing data on the hard drive.
