I don't think you need to try others distros. Try manually removing and reinstalling.
You can manually install the kexts.
1.
Remove all video related kexts (nvkush, nvinject...)
2. Copy NVinject.kext to /System/Library/Extensions
3. In Terminal write:
Code:
sudo chmod -R 755 /System/Library/Extensions/NVinject.kext
4. Copied NVinject.kext to /System/Library/Extensions
5. Enter your admin password when prompted
6. In Terminal write:
Code:
sudo chown -R root:wheel /System/Library/Extensions/NVinject.kext
sudo rm -R /System/Library/Extensions.kextcache
sudo rm -R /System/Library/Extensions.mkext
7. Restart using the boot flags:
-v Verbose
-f Ignore extensions cache
-F Ignore com.apple.boot.plist settings
If use any other boot flags add them to number 7.
P.S. this is a copy of a post I did a few days ago.
