borissatan Posted April 23, 2012 Share Posted April 23, 2012 Hey guys I've just built a new 10.6.8 disk (upgrading from 10.6.7 failed miserably) and everything seems to work ok except the graphics card: My main monitor is DVI-D Dell 2711 and this only comes on if I have a vga screen also connected to the graphics card. With both screens connected the VGA is active during boot up and the DVI takes control once desktop is reached. If I turn on the computer with just the DVI screen attached I see the boot up sequence on it but then it goes black at the point it should switch to the desktop. Argh! Am I being stupid?? Thanks very much for any help you guys can give! Mobo is Gigabyte EX58 UD5 btw Link to comment https://www.insanelymac.com/forum/topic/278415-1068-9400gt-weirdness/ Share on other sites More sharing options...
borissatan Posted April 23, 2012 Author Share Posted April 23, 2012 Oh my installation method was ###### + ###### using the EX58-UD5 DSDT (F12 version although I have only F7 but I figure this isn't the problem?)

kmisterk Posted April 23, 2012 Share Posted April 23, 2012 If you can, use a DVI to VGA adapter during boot up. Had the same issue on an ati 4870. Had to use the adapter to show the desktop at first boot, then installed the updated kext for my video card Link to comment https://www.insanelymac.com/forum/topic/278415-1068-9400gt-weirdness/#findComment-1815708 Share on other sites More sharing options...
borissatan Posted April 23, 2012 Author Share Posted April 23, 2012 yeh i'm with nvidia though so this 'should' be fully supported by the os. and the DVI monitor DOES work, but only when i boot with the VGA monitor attached. doesn't make sense to me... i've tried installing the latest nvidia drivers and it says I already have them so there's something else going on.... hmn??

rlf Posted April 23, 2012 Share Posted April 23, 2012 Maybe for grins you try installing NVEnabler. Use enclosed Kext Wizard to install it in /System/Library/Extensions. http://www.osx86.net/view/2587-nvenabler.html Link to comment https://www.insanelymac.com/forum/topic/278415-1068-9400gt-weirdness/#findComment-1815716 Share on other sites More sharing options...
kmisterk Posted April 24, 2012 Share Posted April 24, 2012 That is weird. Yeah, I've only ever noticed that particular issue when I initially install Retail 10.6.3. That's how my radeon 4870 card functions OOB without any extra drivers.
