Chipset or Video Card problem?
 
Ok i got my mac PERFECT! Only one problem.. The screen is fuzzy and the text is kinda unclear.. My video card is Nvidia Geforce 8400GS. And i installed Nvinject and got my screen fixed.. but the screen is still fuzzy and the text are unclear and its horrible to watch the screen. Is it the Chipset problem? or my Video Card?
Beacuse i dont know where to find a kext that support my Chipset. Intel i945P :(

Can i fix it?

Have you used any EFI strings for graphics in your com.apple.Boot.plist?

Remove your extensions cache. Open Terminal and type:
Code:
sudo su
rm -Rf /System/Library/Extensions.mkext
Reboot using the -v -f boot-flags

If this doesnt work we can manually remove NVinject and than reinstall it with the proper permissions.

Saulidava 01-31-2010 03:13 PM

Well lets try to reinstall it.

Get a fresh copy of NVinject 0.2.1 and make sure it is on your Desktop http://nvinject.free.fr/files/Latest_NVinject.0.2.1.zip

Remove the existing NVinject using the following command
sudo su
Code:
rm -Rf /System/Library/Extensions/NVinject.kext
The following commands will backup your extensions and install NVinject with proper permissions and ownership. An explanation for each command is provided below.

Code:
sudo -s
mkdir /backup
cd /System/Library
cp -r Extensions/ /backup/
cp /Users/YOUR_USER_NAME/Desktop/NVinject.kext Extensions/NVinject.kext
chmod -R 755 Extensions/
chown -R root:wheel Extensions/
touch Extensions/
rm -rf Extensions.mkext
diskutil repairpermissions /
Reboot using the boot-flags -v -f


Manually Installing a Kext EXPLAINED
You can manually install drivers (kexts) by following the instructions below. Be sure to do your research and make sure that what you are installing will work. It is highly recommended that you do steps 2, 3 & 4 to backup your extensions folder. This will make it possible to recover from a non booting system

Place the kext you wish to install on your desktop (The following commands rely on it being on the desktop).

1. Give yourself root privileges so that you can modify files.
Code:
sudo -s
2. Make a backup copy of your kexts. First we will make a directory called "backup" in our root directory to store them. Open Terminal and type:
Code:
mkdir /backup
3. Change directories to /System/Library This will shorten some of the commands we have to type in.
Code:
cd /System/Library
4. Copy your kexts to the new "backup" folder.
Code:
cp -r Extensions/ /backup/
5. Copy the kext from your desktop to the extensions folder (Replace YOUR_USER_NAME with yours)
Code:
cp /Users/YOUR_USER_NAME/Desktop/NVinject.kext Extensions/NVinject.kext
Repeat step 5. for each additional kext.

6. Set the proper permissions for the extensions folder.
Code:
chmod -R 755 Extensions/
7. Set the proper ownership for the extensions folder.
Code:
chown -R root:wheel Extensions/
8. Touch the extensions folder
Code:
touch Extensions/
9. Remove the extensions cache to force OSX to rebuild it with our new kext.
Code:
rm -rf Extensions.mkext
10. Repair permissions to your drive.
Code:
diskutil repairpermissions /
11. Reboot using the boot-flags -v -f
-v Verbose Mode displays useful information during the boot process.
-f Forces OSX to load kexts from the extensions folder instead of the cache file. We did delete the cache file so this is just a precaution.

You need to make sure that you only use one at a time so if you had an EFI string you should have removed it prior to trying NVinject
