So I had Crossfire running on 14.04, but I decided to update to 15.04 and now it's acting strange. I've gone through the typical steps of commenting out everything in
/etc/init/gpu-manager.conf, and I've ran through the process of executing:
sudo aticonfig --initial -f sudo aticonfig --adapter=0,1 --cfa sudo aticonfig --adapter=0,1 --crossfire=on
multiple times and each time the Crossfire bridge shows up when I run:
However, any time lightdm restarts, either during a reboot or restarting lightdm manually, running
aticonfig --lsch again returns
No Multiple GPU chains defined.
I've even gone so far as to replace
/bin/gpu-manager but even then the problem persists. The issue also doesn't appear to be with the
/etc/X11/xorg.conf file because it doesn't get overwritten anymore.
