Hi there. I’m hoping someone can help here, before I go completely over the edge. I bought an old iMac from eBay recently and decided I’d install Linux on it, as macOS was a bit slow. I’ve tried installing multiple distro’s - Arch, Ubuntu, Mint, Manjaro - but I’m running into issues with the display that are affecting them all.
Spec is: late 2009 iMac (10,1)
3.06Ghz Core 2 Due E7600
12GB RAM
AMD Mobility HD 4670 (256MB)
If I boot a live installer for an distro, the main Mac screen splits into four distorted, identical images. I can add “nomodeset” to the boot options and this will temporarily sort the issue. If I don’t add “nomodeset”, I can plug an external monitor into the mini-display port and the display jumps onto this a few seconds after booting, after which I can install or log into Linux. Weirdly, when I do this, the backlight is on on the Mac screen, but there is nothing displayed on it.
I’ve gone ahead and installed Manjaro KDE onto the machine, which I really like, hence my reasoning for posting here to try and get it working. Once I log in, the OS can see that I have two monitors connected and I can move the pointer over to the Mac screen.
This is a brand new fresh build - I have installed Manjaro multiple times recently/today - so I’ve left it as virgin as possible just now, while I seek help here. I haven’t configured an Xorg .conf files (I previously did and wasn’t sure if that helped or not).
I’ve copied some logs in below - if there’s anything else I can supply, please let me know. Thanks
