The maintainer of VoidLinux has also a Terascale running in his G5: https://imgur.com/Drt5KYoWhat about the xorg.log or xorg config file? Maybe you have to blacklist the other card in Grub? Regarding X1900, the Mac Edition won’t work on Linux, because of the reduced BIOS, IIRC.
Hello Karl,thank you for these hints. Ok, won’t try the X1900 then. I would try further investigation and debugging (modules, xorg and so) if I knew that card should work. But it seems especially the HD 5xxx series does have problems regarding backward compatibility:
