The radeon driver only supports 2 screens per GPU in Zaphod mode. Unless you really need multiple X11 protocol screens and/or static configuration in xorg.conf, I'd suggest trying without xorg.conf and letting the desktop environment manage the display configuration via RandR 1.4. Note that in this case I highly recommend using at least the xf86-video-ati 7.8.0 release, possibly even current Git master, and ideally a newer version of Xorg as well. Alternatively, you could try combining two displays per Zaphod screen, but I'm not sure that'll work out.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
