Created attachment 45851 [details] System Information (emerge --info) Hello, I'm running a gentoo amd64 installation on my Dell Precision M6300. It resides in a docking station, so I don't have to connect 10 cables, when returning to my desk. My external Monitor (HP LP2475w) is connected via the DVI-D connector at the docking station. "xrandr -q" lists the monitor. But if I enable it the monitor stays blank, showing a "no signal" message and goes to sleep. Unplugging and replugging doesn't improve it. The monitor is also listed in the Monitor section of the system settings on my gnome 3 desktop, but it's the same game like with the xrandr command line tool. BUT, if I take my Laptop out of docking station and connect the monitor to the DVI-D connector of the Laptop I immediately get a signal. From what I can see, it seems that the signals don't get remapped, when the Laptop is inside the docking station. Just a guess. With the proprietary Nvidia driver this configuration works just fine (except that the suspend is not working with gnome 3). Please tell me the logs/debug messages you need, I already attached some. Thanks in advance, Alex

Can you mail the vbios image from /sys/kernel/debug/dri/0/vbios.rom ("mount -t debugfs debugfs /sys/kernel/debug" if not already done) to mmio.dumps@gmail.com, and mention this bug number in the subject.

I'm experiencing the same bug, the second monitor does function via the proprietary nvidia driver and if I switch the DVI connections to both monitors the one that's stating no signal swaps around with nouveau, so I don't suspect any hardware faults. I've posted my vbios.rom here: http://lyte.id.au/stuff/vbios.rom.gz I can email it directly as well if required...
It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report. In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one. Thanks, The Nouveau Team
