Project Update:
I had the opportunity to try using some different LCD panels with my iBook Clamshell. My wiring is the same as it was during my last post. Here are the results:
IDTech IAXG01A: Screen completely black --doesn't work --this is the LCD I bought on eBay.
Samsung LTN121XJ-L01: Graphical glitches, no picture --This is the screen from my A1010 PowerBook G4 12"
Samsung LTN121X1-L02: Semi-functional!!!!! -- This is the screen from my Snow M6497 iBook G3
These tests prove that the iBook Clamshell is very picky about which LCD panels it will tolerate for the XGA mod. I connected my supposedly "broken" IDTech panel to my PowerBook G4 and Snow iBook G3, and it worked perfectly with them. I plan to install the IDTech panel in my Snow iBook G3 and swap its functional Samsung panel into my Clamshell.**
While the new LCD panel works with my iBook Clamshell, I have not yet gotten the XGA resolution to work, despite running the requisite OpenFirmware commands. Hopefully, this is something that can be fixed in software. I believe that I entered everything into OpenFirmware correctly, as I was able to use the terminal command
Code:
ioreg -l -w0 | grep "panel-family"
to verify the answer was 3. I am running what I believe is the most recent version of the iBook firmware, 4.1.7.
Similar to the troubleshooters in the original MacNN forum thread, I've considered running Ubuntu to see if it will pick up the additional screen resolution. If this works, it will confirm that the non-firewire iBook's GPU can handle the additional screen resolution.
I'd greatly appreciate any advice or ideas about getting this iBook to recognize that it's now capable of running at XGA resolution. Paging

**I also still need to perform the LED backlight mod on this new LCD panel, but that's a separate project. Anyway, it's the reason there's no backlight in the pictures above.
