Right after installing linux the iMac G5 does not boot, it shows the lubuntu boot screen and then goes to a black error screen. Please help me. I did not know that PowerPC linux was so atrociously terrible. Every computer that I have tried PPC linux on fails! On an AMD64, ubuntu installs perfectly. I am not hating on linux, I use it all the time on AMD64, I am just saying that it has never worked for me on PPC64. I love AMD64 linux, and would love PPC64 linux, if it worked.
