Need help. My Lenovo G450 laptop does not recognize my video card. I tried to search in the internet on how to resolve this but ended up at nothing. I tried to look for people who has the same laptop specifications or at least the same but they too could not find any solution for our problem. Could someone try to modify the kext for X4500 GMA? I found a forum that says it can be modified to work for the chip. Any help will be greatly appreciated!
