ok..i solved..
 

Though i have installed 9f23..the problem is most of these pkgs wont replace existing files. so I extracted required files. in my case all GE force files, NV* files and replaces them with what was there in the packages. Actually i removed those files and the then installed new files using kexthelper. restarted...cool it works...no issues as now.. Wake from sleep is an issue..completed disabled. Otherwise rocks..survived 40+ shutdown..start..60+ restarts no issues :) Hope you have EFI installed. if so then remove all the NV* files from single user mode and then restart. You will mostly have workable system with Non QE/CI..now open 9f23 in pacifist...look for Nvidia files and just extract those to desktop. Now remove all equivant files from your extensions and install these using kexhelper or similar installer or manually. Give it a try..it might help...as now i dont have natit/nvkush/nvinject..it works with out them...be cautious with wake from sleep. hope it helps..u can try same way for ATI as well

So your saying its a video kext package installer?

more specifically 9f23

Oh. Because I tried iDeneb 1.4 10.5.6 and used NVinject 0.2.1 512mb and got the same mouse issue.

same problems.
 

Hi, I'm having the same problems as you laterusman. If you fix it, please post here again!

I'm using iDeneb 1.4 with this setup:

asus m2npv-vm, athlon 64 x2 4000+, sata hd, with an asus 8800GT (g92) attached.

Using voodoo kernel, removed the appleuserupstream kext (or whatever its called) installed using nvinstaller, (no nvinject), using fsb=200000000, and have tried cpus=1 to no avail. The problem even occurs when i boot in safe mode :(

the thing is that it starts working for a bit then gets the jumpiness. I wonder if theres a process run by launchd causing it?

one thing I did notice, is i went to the console and opened the system log, there were a lot of messages like this:

Mar 21 11:11:50 <myhostname> kernel[0]: IOHIDSystem::relativePointerEventGated: Unwanted Direction Change Y: oldDy=-2 dy=5

Weird nickdanger because for me as of right now. I'm in my iPC 10.5.6 install and everything is fine I booted in to safe mode one day and I didn't have the lag so I figured I that may have fixed it and so I restarted and everything's been fine.
Been working almost exclusively in os x using parallels and photoshop.

I'm still getting the mouse bug randomly....could it be an application? or is it the Voodoo kernel? thats giving me these problems.
I never got it on iDeneb 1.3. Which had a different kernel for AMD users.

I'll have a working system one boot then if I restart and log back in my monitor shows no signal then I see the mouse for a second on a blue background then that screen goes away then I get to the desktop and my mouse is jumpy and sluggish. Booting cpus=1 or fsb= doesn't work.

This is getting annoying.

I just reinstalled cause I was having a similar mouse issue. nagu's advice is what fixed mine. You must remove the existing video kexts.

Installed iPC with nvidia mac pro (no injectors!)
Used kext helper b7 to fix my wifi (also created /Backup Extensions)
Downloaded the 9f23installer.pkg
cd /System/Library/Extensions
sudo mv GeF* /Back*
sudo mv NVD* /Back*
Run 9f23installer
Use osx86tools to add the EFI string
Reboot -f -v

No more mouse lag! Both screens on my 8800gt 512mb card are working at full res. :D

ok how do I fix this bug in snow leopard? since I can't install leo nvidia kexts.. what do I do?
