When I installed the 3.13-0.bpo.1 kernel the kernel command lines were fixed. What caused the original failure were the explicit mode settings I had on the kernel command line, namely "video=DP-1:2560x1440-24@60e video=DP-2:2560x1440-24@60e video=DVI-0:2560x1440-24@60e". I had to add those settings in the past (see <a class="bz_bug_link bz_status_NEW " title="NEW --- - radeonsi/KMS: Displayport mode detected incorrectly" href="show_bug.cgi?id=72167">https://bugs.freedesktop.org/show_bug.cgi?id=72167</a>.) Without them settings it works. I'll attach some kern.logs - there all sorts of interesting things going on that are apparently needed to get the DP outputs up and running with my DP->DVI converters. Setting the resolutions explicitly keeps those interesting things from happening.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
