harshil Posted October 3, 2011 Share Posted October 3, 2011 Hello everyone, I have a vanilla fully working Snow Leopard setup, relevant specs are: - HIS 4870 512mb (2 DVI, 1 S-Video) - Gigabyte GA-EX58-UD3R rev. 1 motherboard - I7 920 CPU - 1 Samsung 1440x900 Monitor - 1 Sony 1280x1024 Monitor VGA only (Secondary) I received the secondary monitor just yesterday, prior to receiving it, my setup worked perfectly by having the primary monitor connected through DVI and a dvi2vga adapter placed into the second DVI port (without anything connected to it). Now when i add the secondary monitor by connecting it to the DVI2VGA adapter that was already present (it is a VGA only monitor), it works perfectly without any glitches and full acceleration and resolution, but when i put my computer to sleep, this second monitor no longer receives any signal though the OS still detects it and works under the impression that it is connected. I would much appreciate help with getting this second monitor working after waking from sleep, i've searched around, but i cant find anything for snow leopard and my setup, only for leopard. I would appreciate anything anyone can offer in this regard. Thanks everyone!

tbob22 Posted November 30, 2011 Share Posted November 30, 2011 Same problem here. I have unfortunately not found a solution yet. This also happens in Lion, and after the monitors go to sleep. Fixed it!! Added this to my /Extra/org.chameleon.Boot.plist (com.apple.Boot.plist on older Chameleon versions): <key>Kernel Flags</key> <string>PCIRootUID=1</string> Monitor sleep and full sleep now work perfectly!
