I just got a tip from David De La Harpe Golden to try a analog adapter. When DVI-1 is connected via analog cable, the second screen works. Xorg.log is attached. Created attachment 25670 [details]
Xorg.conf when DVI-1 is connected to analog VGA
Just to note, I just started seeing a highly similar issue with radeonhd on a hd4870x2 following upgrade to debian/unstable's current xorg (which is 1.6.1) (In reply to comment #5) > Just to note, I just started seeing a highly similar issue with radeonhd on a > hd4870x2 following upgrade to debian/unstable's current xorg (which is 1.6.1) > ... aaand the problem went away for me (n.b. I'm not Andreas) again upon cold reboot this evening after the machine (both computer and monitor) had been powered off at the mains for some hours. Ho hum. I tried with today's git, DVI still doesn't work, VGA works as workaround. Created attachment 30575 [details]
my dmesg
As requested on the xorg-driver-ati mailinglist, I'm attaching my dmesg and xorg logs. I have a similar problem as the one described in this bug: after boot with KMS enabled, the screen comes up either completely blank or with vertical colored stripes. The console still reacts to keyboard input. The monitor is an Asus laptop LCD screen.

Actually my problem may be more similar to bug 24587. can you try with ati from git master? Specifically commit 66b194a78c470cb3978f310828dd96c3f3e96944. Can you try with the latest code from xf86-video-ati git master? I just committed some new PLL code that might help. Hi! I have no second DVI cable here, but after christmas I'll try! Have tested it with latest git master branch. Commit bd011784c0609f1fd03dcb784744c8f5cdef33da. Works for me now. Thanks to Alex Deucher. Just tried it. No luck with today's git master (newest commit: 30a19b75cc82b8e04c45e6684b84f9a4ccc0505b). I'm using x server 1.7.4 now and kernel 2.6.32. The problem didn't go away, the monitor still stays black and xrandr still says it's working... I upload the current Xorg.log Created attachment 32741 [details]

The DVI-1 connector doesn't work with the following PCI-E card (Sapphire HD 3470, passively cooled) and the current radeon driver from git: 01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3470 The card has two DVI connectors. xrandr output says that the DVI-1 output should be working, when I take a screenshot, it has the correct dimensions. Screen 0: minimum 320 x 200, current 2960 x 1050, maximum 2960 x 1050 DVI-1 connected 1280x1024+1680+0 (normal left inverted right x axis y axis) 338mm x 270mm 1280x1024 60.0*+ 75.0 72.0 60.0* 1152x864 75.0 1024x768 75.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 640x480 75.0 72.8 66.7 59.9 720x400 70.1 640x350 70.1 DVI-0 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm 1680x1050 59.9*+ 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1280x800 74.9 59.9 1152x864 75.0 1152x720 60.0 1024x768 75.0 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 59.9 720x400 70.1 At Xorg startup the monitor connected to DVI-1 seems to be initialized because the monitor wakes up from standby, but immediately displays "No signal detected" and goes to standby again. When I swap the connected DVI cables, the other monitor works (in fact only the monitor connected to DVI-0 works), so no hardware defect. I previously used this setup successfully with fglrx and radeonhd. The problem seems not to be related to DPMS ('sleep 5; xset dpms force off' doesn't help). Xorg log and config are attached.
