Do you have another Radeon HD4XXX, 5XXX, or 6XXX for testing? Do you still use the fbdev driver in your /etc/X11/xorg.conf? If yes, please delete the xorg.conf and try it again.
A friend gave me a couple of Radeons. Not sure of the models, not stamped clearly on the label, but could be 6000 series.
I checked and my system has no xorg.conf. But I found I made up a Radeon-SI config in xorg.d for my R7. I don't recall if it had fbdev. Will need to disable and retry.

If you have two graphics cards then you need a special xorg.conf.
Yes I do. Though I did test with both and with only 5450. I put the R7 back so I had a display. I found the 5450 still works on my old Ubuntu. But hang on, how does my old Ubuntu support both cards?
Also, every time I boot I see two Penguin sprites. Is that because I have two graphic cards?

X11 has simplified a lot. But it's not up to the point of auto detection unfortunately. Ok so I tried to follow the format and copied the PCI name as listed but it still didn't like it. In fact I made it worse. The X11 log usually lists all chipsets. But now it drops immediately with unknown screen error.
I had to edit it in Ubuntu. But I wonder if the PCI list has it in the same spot? Also, something is wrong with my Fienix, because it doesn't have lsusb or lspci. This makes it hard to work with. I've logged in as root. How come these common commands don't exist? I'm always getting stuck like this.

Further information:
Thanks for the info!
I'll likely remove the 5450 after experimenting. It exposes a CFE bug. Colours are messed up on R7. I suspect because the R7 is little endian only and 5450 is bi-endian. It just looks that way.
