I have a Dell Inspiron 1545 that I've used iAtkos v7 to install Leopard onto. It works wonderfully but I have suffered with the common issue of not being able to get anything but 1024x768, ultimately making it so I'd rather put my Win7 drive in than use the Mac install. I finally decided yesterday it was time to try again and I have gotten further than ever before. I used the myriad of pinned threads in this section of the forum to get here. Ultimately what seems to have worked was the AppleIntelGMAX3100FB.kext shared here in combination with the replacement DSDT.aml however I also had it working at one point with the DSDT.aml that installed with iAtkos.
I've searched and read so much over the past 24 hours on this topic and I can't find anyone quite having the same issue as me which is why I'm posting a new thread. Apologies in advance since I know there are SO many on this topic.
As I type this I am in 1366x768 (which is where I want to be) but I gaurantee that on my next reboot I'll have my issue again. My issue I lovingly refer to as my screen "melting." I get the grey screen with the apple followed by the solid blue screen but when it goes to bring up my desktop the screen does this odd thing I can only describe as melting. It's a mix of white and grey colors with vertical lines and the colors slowly move around the screen. The white merges in and covers the grey in the center very slowly and then eventually more grey moves in to cover the white etc. I've attached the only photo I could get (sorry I know it's not great - the horizontal lines you see are only visible in the picture, not on the screen). After this happens, when I reboot, my screen flickers like mad for a few minutes, even in single user mode.
I've tried two installations, one with applying the update to 10.5.8 first before the kext etc. and one without doing squat after the base install before installing the kext. The part I don't get is that it will work fine on the first reboot after installing the kext in most cases. Note I have had this same experience without running the brightness patcher I found in one of the pinned threads as well but I run it anyway.
When I boot verbose I see a couple things that stick out to me: 1) "Invalid firmware backlight setting" 2) "Family Specific Matching Fails"
The backlight thing sure seems to make sense to me based on the odd melt issue which is what lead me to try the brightness patcher to begin with (even though it was in a thread on HP laptops).
So... any thoughts folks? I know this probably isn't the most helpful post but honestly I'm not even sure where to start with providing information so by all means let me know what you need and I'll provide it. For now, I'm refusing to reboot my laptop.
