Thread: nvidia 9800 GT

I've had Lion running since release and has worked fine with my Nvidia 9800 GT until I applied the
10.7.3 update. After installing update and rebooting the monitor goes black.

If I enter my login password at the black screen, Lion appears to continue as evidenced by heavy
disk activity. However, the screen remains black and appears disconnected from the system.

Any suggestions or help would be appreciated.

Thanks

yep !!

I take it that this is a plist that you edited.

What plist is this?

org.chameleon.boot.plist or com.apple.boot.plist. Both usually in Extra folder.

ok, I added those items to my boot.plist and 10.7.3 still boots to black screen at the logon prompt.

With those items in or out of my boot.plist I can boot successfully to 10.7.1

Here are the plists I use

Com.apple.Boot.plist with additions - Works with Lion 10.7.1 but not 10.7.3

com.apple.Boot.plist without a dditions - works with Lion 10.7.1

I don't think this is a plist issue in going from 10.7.1 to 10.7.3

My system is as follows
ASUS P5Q3 Deluxe
Intel Core 2 Duo E8500
8gb of memory
Nvidia Geforce 9800 GT
