When I swap the DVI cables, the other display works. The DVI-1
connector as the radeon-driver calls it doesn't work at all. It's
initialized at Xorg startup (monitor LED turns from orange to green and
the monitor displays "No signal found"), but stays blank. Really no
idea about that? It would really be great if I could use both monitors.

Best regards,
