fglrx drivers not working after upgrading to ubuntu 14.04

I was on ubuntu 13.10 and was using manually installed amd beta graphics driver. Mfter y system has a hybrid Intel hd4400 and AMD Radeon 8670M graphics card. After upgrading to Ubuntu 14.04 it booted to black screen. On tty1 I tried to run fglrxinfo , it returned "Command not found"
Then I did
sudo apt-get -purge fglrx*
sudo reboot
after rebooting got the same problem
tried to install the same driver
using
sudo ./amd-driver-installer-13.35.1005-x86.x86_64.run
and followed the instruction, then got an error msg "installation failed"
tried manually building and installing, first it failed, then using Synaptic packet manager I fixed broken packages then tried to install , it installed , but on
sudo aticonfig --initial
it says unable to find command aticonfig
rebooted again and ran
fglrxinfo
again unable to find command.
Errors were found in processing
