SteWie09 Posted July 4, 2009 Share Posted July 4, 2009 Hi there, this was my first OSx86-installation and it ran unexpectedly good, but: "Graphics Mode" above 1280x1024 without effect The OS is not able to detect the monitor. Therefore I am not able to set the native resolution of my widescreen DVI monitor. I am stuck with the default resolution 1024x768. By setting then "Graphics Mode" at the kernel boot settings, I can push it to 1280x1024. A higher value has no effect, no resolution above 1280x1024 seems to be possible (but at least there are no artifacts). Blue screen after kext-replacement After reading this forum for hours and nights I followed suggestions to replace AppleIntegratedFramebuffer.kext and so on lead me to a full blue screen. The OS seems to boot up, but I am not able to see anything, because I only have the pure DVI monitor and I am not able to check a proper VGA-Output. SwitchResX The next suggestion in this forum was the installaton of SwithchResx. But without success: no widescreen resolution could be established. Who can help me to run full widescreen resolution (goal 1920x1080x32, Full HD) with the Intel GMA950 on an external DVI-Monitor? This is my configuration: Installation suite: iDeneb 1.4 (Leopard 10.5.6) The Computer is a Hush E1 Basic Media Center (-> no Laptop) Mainboard: Aopen i945GTt-vfa with GMA950 graphics on board, DVI-I-Video output (VGA via Adapter) Monitor: Apple Cinema 20" (DVI-D) HD-Screen: Panasonic 50" Plasma (via DVI-to-HDMI) full HD Many thanks in advance!

Azimutz Posted July 5, 2009 Share Posted July 5, 2009 Hi.. How about DSDT fix? Did ya try it... I think it will work with your mobo. Works fine for me with Leo and Snow, same chipset as you. You can also apply the patch to DSDT with ACPI (DSDT) Patcher, under Windows. Se ya..

SteWie09 Posted July 5, 2009 Author Share Posted July 5, 2009 Hi Azimutz, thank you for your suggestion. I did the DSTS patch with Dr. Hurt's guide but now I get a blank screen (no signal) after reboot...Help! Do I need another boot loader? I am using the Darwin/x86 boot v5.0.132 - Chameleon v1.0.12?

Azimutz Posted July 5, 2009 Share Posted July 5, 2009 Hi.. Did you restored "stock" kexts? DSDT fix works with "stock"(original) kexts... You mentioned you used old framebuffer, at least... Edit: Remembered another thing.. I don't know if this works for DVI output?! Test VGA out too.

Edit: Remembered another thing.. I don't know if this works for DVI output?! Test VGA out too. Hmmm...I thought with the fresh iDeneb installation I got the original kext? On the other hand I installed the GM950 patch from the iDeneb DVD... Could you please give me a hint where to find the "stock" kexts and how to do the restore? Many thanks!

Hum.. first check iDeneb DVD for S/L/E folder.. i think it doesn't have it (it's removed for faster loading and extra space). If the folder is there, the files are too. If not, download 10.5.6 update from Apple, open the pkg installer with Pacifist, find AppleIntelIntegratedFramebuffer and AppleIntelGMA950 kexts, right click, extract and install with any tool or install directly from Pacifist. You can always install the system fresh and don't select GMA950 patch on iDeneb If it's the same "old" patch, it only installs old framebuffer. And the bootloader doesn't have nothing to do with it!

I did another test and borrowed and connected a VGA-monitor, and...it works! That means that the compiled DTDS.aml is ok, but I am not able to drive the DVI-port. That's not satisfying, since I do only have DVI/HDMI-devices in my household. frustrating...

Azimutz Posted July 6, 2009 Share Posted July 6, 2009 damn well.. maybe it's time to give those displays a "better" graphics card.. afaik, your mobo has a PCIe slot. Can't help more, in this case. If you need help for any other, just yell See ya..

zcream Posted March 14, 2010 Share Posted March 14, 2010 Hi Stewie. Is SL working on the i945GTt ? I am thinking of trying a SL install, and using the PCIe x1 for a BM Intensity card.

TennisGeek Posted March 23, 2010 Share Posted March 23, 2010 Hi Stewie. Is SL working on the i945GTt ? I am thinking of trying a SL install, and using the PCIe x1 for a BM Intensity card. FYI: I bought nVidia Quadro NV290 PCE express x1 off ebay $90, and with patched DSDT, I got CI/QE fully working. NV290 is pretty much equivalent of 8500. -- TG Link to comment https://www.insanelymac.com/forum/topic/173563-intel-gma950-and-dvi-display/#findComment-1433676 Share on other sites More sharing options...
bkr Posted November 14, 2010 Share Posted November 14, 2010 Is SL working on the i945GTt ? I have an i945GTt-VFA and sadly I'm not able to install any Hackintosh on it. I've tried iDeneb v1.6 10.5.8 and Snow Leopard 10.6.2 MacOSX Intel/AMD-Hazard. I always get this bootlist-error. I also tried the nawcomModCD but I get the "match_kernel"-error then. Of course I use the newest Aopen-Bios, S-ATA-Harddisk, USB-DVD (I've tried an USB-Stick with SL, but the i945GTt-VFA did not boot from bootable USB-Sticks ). I have no idea what else I can do to make in Hackintosh out of it. What works: I can use the HDD from my Thinkpad X61s with iDeneb on it, connect it with the i945GTt-VFA and it boots and runs smoothly! Update: I managed to install Hazard's 10.6.3 Because the OS X-Installation does not accept my external DVD-Drives (USB2, IDE) I use the hdd-utility to create two partitions (mac os extended journaled, option MBR). Then I recovered the Hazard-OS-X-ISO on the second partition. Problem: The Board did not boot from the partition. My solution: I connected a second hdd with iDeneb I normally use in my thinkpad with the board, pressed "alt" while booting, choosed the partition with the recovered image. I did not choose many packets - the 10.6.2 update, the chameleon bootloader, the BIOS patch. The DSDT patch did not work and for a noob like me it toke hours to localize the error and to find a solution. Believe it or not, I couldn't find a good tutorial for fixing the cmos checksum error problem. But fixing is easy. The DSDT Patcher was already in the root folder: double click on "DSDT Patcher Gui", choosing "Darwin", "Force Compile" and "New HPET Option", getting a sessions folder, inside there is a "dsdt.aml" (besides "Debug"-Foder and "build.log"). I checked several compiling/decompiling tools (like iaslme ...) and can recommend the "DSDT Simple Editor" (DSDTSE): Decompiling "dsdt.aml", changing one line inside the resulting "dsdt.dsl" (the line is beneath "Device (RTC)", there is "0x04, // Length", it has to be "0x02, // Length" - "0x02" instead of "0x04", that's all!), compiling the dsdt again and putting the new "dsdt.aml" in the root folder. The cmos error is gone! Now the hardware recognition is wrong. I have a core duo T2400 (1,83 GHz), it says it's a Core2Dou 1,93 GHz. I use 4 GB RAM DDR2 667 MHz, it says there are 3 GB 1600 MHz DDR3 RAM. Stupid. Rember says there a 2 x1 GB RAM and four banks. Stupid.
