After the 10.5.6 update, my Macbook pro has no video at all. I can screen share with it, and its functioning fine. I can't reinstall OSX and restore from time machine because I can't see the screen during the OSX install because Leapord's VNC layer is not loaded during the install. AND i'm surprised that the boot disc does not make video come back on. I know it sounds like I have the bad nvidia chipset issue, but this happened the VERY first reboot after 10.5.6 update. What am I gonna do with this machine now? ARG!
