superpete Posted January 27, 2010 Share Posted January 27, 2010 Hi all I have a Radeon Mobility HD 4650 (1gig) on a HP dv7 - 2166tx notebook running SL 10.6.2. When it boots, it goes through the normal boot process before the screen goes blank (not off). I can VNC into the machine, and it is running. System profiler says this on the card: ATI Radeon 4600 Series: Chipset Model: ATI Radeon 4600 Series Type: GPU Bus: PCIe Slot: Slot-1 PCIe Lane Width: x16 VRAM (Total): 1024 MB Vendor: ATI (0x1002) Device ID: 0x9480 Revision ID: 0x0000 ROM Revision: 113-B7710C-176 EFI Driver Version: 01.00.318 Displays: Display Connector: Display Connector: So it looks like it has detected it properly, but not a display. I have tried the vga and HDMI outputs on the notebook, but both connections seem dead. I am using netkas.org's beta booter as well as the drivers from #radeonhd. I have tried with -pci1 and -pci0 with no luck. Any suggestions? Link to comment Share on other sites More sharing options...
