I've started experiencing some display issues with my MacBook 1,1 it was intermittent but now is every time I boot. Lets start off by saying I have rEFIt installed and have a triple boot system set up. Removing rEFIt does nothing to fix the issues and doesn't seem to be the cause. What happens is when I boot I don't get anything on my display until it comes to the login screen for OS X, at that point all I get is a bunch of vertical line, that are about the right color for the background picture. If i press the power button and return the machine will shut down (normal not forced). This was annoying it had been happening for a few days but restart would usually fix it. Now today it only boots like this. I had the idea to hook up an external display so to try to see what if anything shows up. Everything shows up on the external display which Mac OS detects as the primary display. At this point if I go into the displays preferences I can set the internal display to 1280 x 768 (not 1280 x 800) as it should be and it will display semicorrectly, the missing 32 pixels are all displayed a one really tall pixel at the bottom of the screen. The other thing is that this display isn't called Color LCD like it should be it's called "display". I get a similar behavior if booting onto Lepoard DVD so I cannot even reinstall the OS. For further information it boots to Windows 7, need externial monitor hooked up to see rEFIt screen. But in windows if i adjsut the monitor to maximum brightness the backlight goes off, one level below maximum and everything is OK. Resetting PRAM did not do anything to fix the issue. Here is the info from system profiler: Intel GMA 950: Chipset Model: GMA 950 Type: Display Bus: Built-In VRAM (Total): 64 MB of shared system memory Vendor: Intel (0x8086) Device ID: 0x27a2 Revision ID: 0x0003 Displays: Display: Resolution: 1280 x 768 @ 60 Hz Depth: 32-bit Color Core Image: Hardware Accelerated Main Display: Yes Mirror: Off Online: Yes Quartz Extreme: Supported Built-In: Yes Display Connector: Status: No display connected HELP!!! Thanks!
