Besides my MacBook Pro, I got an old PowerMac G5 which should become my desktop. MacOS 10.5 was installed on it but you don’t get any updates. So I decided to install Fedora and to get a little bit back to the roots because I grew up with Linux. I did the installation with an old 15” monitor and a keyboard I found somewhere in a box. It all went fine, so I took this heavy thing to my student room, connected it to my 22” monitor (with 1680x1050 pixels), turned it on and got a black screen after the bootloader.
It turned out, that the duallink and the so called “phantom” display ports are the reason for that. These posts from str8bs helped me a lot, I got something on my display, but it was only a small part of the desktop. I tried both DVI-ports, nothing helped.
Today, I talked to a fellow student about my problem. He adviced me to get rid of the DVI-to-VGA adapter and to try it one more time. Well, I honestly couldn’t think of a reason why this adapter has something to do with my problem, but I gave it a shot, one last try. And it worked.
My configuration is as follows:
yaboot.confappend="nouveau.duallink=0 video=DVI-I-1:d video=DVI-I-2:1680x105-24@60 video=TV-1:d"Unfortunately, repositories like RPM Fusion don’t support the ppc architecture anymore, so you have to build packages like VLC by yourself.
