danushka Posted August 20, 2009 Share Posted August 20, 2009 Hi InsanelyMacs I am new to Mac but wanted to try by installing IDeneb 10.5.5 in to my PC. managed to install and boot up properly. I also get the OSX boot screen. But when VGA card begins to fire up i loose the VGA Signal to the monitor and monitor says "No Signal". I have following System in my PC. Intel Core2Duo 2.53 GHz CPU FoxConn G31MX-K Motherboard with Intel ICH7 Chipset 2GB Ram (irrelevant in this case ) Nvidia Geforce 8500 GT 512MB VGA card ( I chose 512 mb driver option in VGA section of OSX customizations ) 2 Hard Drives (irrelavent because OSX boots up properly ) Again the problem i have after proper IDeneb 10.5.5 installation and boot up , i loose the Video/VGA signal from VGA card to the monitor after OSX boot screen appears. ( i feel this is the problem with OSX's vga driver for my card ) How do i fix this ? Please somebody help me .

DavidEye Posted August 20, 2009 Share Posted August 20, 2009 danushka: ..great.. I have the same problem. I'm using iDeneb 10.5.7 and on the first boot everything went perfect: Leo started normally, i could configure the network, the video resolution and i managed to install a couple of apps (adium, textwrangler.. nothing too serious). During the first reboot, though, the "no signal" problem appeared and now it happens every time. I can booot using the safe boot mode but then i don't have ethernet connection (is it normal? i'm not sure). My pc specs are in my signature.. as for the drivers i used the ATI 4850 driver that comes in the iDeneb dvd, with the specific mouse lag fix (i tried once without that fix but then the screen flickers every time i move the mouse). I tried to search for an answer in this forum but I couldn't find a topic which addresses this specific problem Any help is appreciated, thanks in advance!

danushka Posted August 21, 2009 Author Share Posted August 21, 2009 Hello, Can anybody help me and David ? Link to comment https://www.insanelymac.com/forum/topic/180696-problem-of-ideneb-1055-no-video-vga-signal-after-boot-up/#findComment-1231490 Share on other sites More sharing options...
DavidEye Posted August 22, 2009 Share Posted August 22, 2009 Hey danushka.. i'm not sure but it seems that i found a workaround for this problem: my video card has 2 DVI outputs.. i tried to connect my first (and only) monitor to the other output, the secondary one, and i got signal again. I had to reconfigure resolution and refresh rate but now this problem is gone. See if it works also for you.. i know that's not a proper solution, just a workaround, but it works quite well actually.

danushka Posted August 24, 2009 Author Share Posted August 24, 2009 hi David , My VGA Card has only one DVI port and one analogue VGA port (25 pin). since my monitor has analogue VGA cable , its connected to analogue VGA signal (25 pin). so i regret to inform that i cannot try your workaround on my system. cheers Link to comment https://www.insanelymac.com/forum/topic/180696-problem-of-ideneb-1055-no-video-vga-signal-after-boot-up/#findComment-1233568 Share on other sites More sharing options...
