Hi Everybody, First of all, I'd like to thank everyone for their efforts in this thread especially Tienneke, coldequation,Trauma & Chameleon 2.


This is my simple solution for Lenovo & GMA X4500 users until we have final driver without mouse bugs & supporting CI/QE, so you can set screen resolution to 1280x800@60Hz or whatever you want & working mouse without mouse pointer disappear.


Please Note, there is NO Kext loaded & no CI/QE, this steps success in my laptop (lenovo 3000 N500 4233-65G).


1--- Make a clean installing for iATKOS_v7 10.5.7 & select one of boot loader (Chameleon v1 or BootThink v1).

*** Don't select Chameleon v2, in my case, I had failed to update it later, or test it at your risk.


2--- Update to Chameleon 2.0RC2 Build r640 & Repair Disk Permissions and reboot twice to ensure that your installation success.


3--- looking for screen resolution available to your machine from (Video Info) in Chameleon boot screen.

Make Test, just boot in (Verbose) mode and type your screen resolution or type this.

-v "Graphics Mode"="1280x800x32@60Hz"

Now, you have 1280x800 fixed resolution without mouse disappear


4--- Run (OSX86Tools), select (Add EFI String/Boot Flag) & Add this code to (Flag) Field

"Graphics Mode"="1280x800x32@60Hz"

Press Apply, Reboot & Success.


Best Regards.
