adro Posted June 13, 2008 Share Posted June 13, 2008 hi all, i have successfully installed kalyway 10.5.2 on my hackintosh with no graphic extensions and vanilla 9.2 kernel. installation was easy and everything works but the screen resolution is blocked at 1024 * 768 which is too low for my 22'' hp display. i have tried to install everything i found on the net, including nvinstaller42, nvinject0.2.1 and natit for dual cards but seems to be noway to get it properly working. i had to reinstall osx about 20 times because after installing some new extension it stucks at boot (evenif i "movevideodrivers" or boot in safe mode) my specs: intel pentium D - 4 gb ram - nvidia 7900 gtx 512 mb - sata 160 hd. i think it's all about graphic... i am kinda desperate,please help!!! thanks daniele Link to comment https://www.insanelymac.com/forum/topic/110332-stuck-with-resolution-nvidia-7900-gtx/ Share on other sites More sharing options...

fr3ak! Posted June 13, 2008 Share Posted June 13, 2008 Read posts about NVinject or go to nvinject.free.fr Maybe you need to edit kext and modify VRAM and NVCAP I have a Go 7950 GTX 512 Mb and need some tweaks to have full function. Another solution consist to modifiy com.apple.Boot.plist and add : <key>Graphics Mode</key> <string>1920x1200x32</string> Where you replace 1920x1200x32 by your resolution. Hope It will help !

Framebuffer works in Safe Mode, but Hardware Acceleration is disabled there. So flash it just.
