@nilesecurity you are using a mobile graphics ATI 4300 
mobile graphics are poorly supported except Intel HD 3000-4000 series
my advice is to backup all graphics kexts and boot without -x

use this terminal command

sudo grafix backup all (works only with my mavericks version)

then reboot

try to find your graphics kexts later

before trying those kexts

replace the backuped kexts using

sudo grafix replace all

Can you explain more

You mean to write this command inside Mac terminal after running in safe mode

Or write it during startup

And what I will do after backup ,delete all grafics kexts or what

All I need to run in normal mode then multi beast will solve every thing,right?
