The first obvious thing to tackle is the unknown init table commands. I've seen another case where these are used, and should have my hands on a laptop that has them at some point in the near future, so I'll tackle them then. In the meantime, it'd be very useful to grab a mmio-trace of the nvidia binary driver initialising your displays as another data point. http://nouveau.freedesktop.org/wiki/MmioTrace has detailed instructions how to grab one. > In the meantime, it'd be very useful to grab a mmio-trace of the nvidia binary

I sent a mmiotrace some weeks ago the the email from the FAQ, did you recieve it?

dmesg output on macbook pro
I see the same problem here with a MacBook Pro and a display connected to the mini DisplayPort via a mini-DP<->VGA adapter. Attaching kernel log, fwiw. The bits about not being able to get the EDID are the same as the original reporter. Happy to help test/debug.
Hardware: Thinkpad T410, NVS 3100M (nva8?) Kernel: vanilla 2.6.39+ from kernel.org + nouveau tree merged Displayport still is not working if not activated by BIOS (xranrd claims that the CRTC is in use, but there is no signal on the display). The mentioned xorg hang disappeared long time ago (in my case at least)... (In reply to comment #6) > Displayport still is not working if not activated by BIOS (xranrd claims that > the CRTC is in use, but there is no signal on the display). I have the same issue on a Thinkpad W510; the display is supposed to be active, but I don't see anything on the screen. > The mentioned xorg hang disappeared long time ago (in my case at least)... I am sorry, just tried to install fedora15 on my T410 and could not continue the install after reboot, because DP was plugged in and xorg would hang infinitely. (machine worked fine though, had to install the blob through USBtty, though :-() what I want to say, this bug is still there in stable releases, my post from the last time was from gentoo and everything installed from git... btw. will DP be useful at any time, or is this a hard to reverse engineer BIOS issue? > I have the same issue on a Thinkpad W510; the display is supposed to be active, but I don't see anything on the screen. on git versions: If I close the lid then will BIOS disable LVDS and enable DP, which then works as expected in xorg, you can even enable LVDS afterwards - so maybe this can work for you until this bug is fixed... This is actually fixed now in the nouveau kernel git tree, closing. I have a similar 34429 bug, which is reproduced on the latest git version. See the attached dmesg log to this bug. (In reply to comment #10) > I have a similar 34429 bug, which is reproduced on the latest git version. See > the attached dmesg log to this bug. It's not the same bug. This bug is about DP outputs not working unless initialised by the VBIOS.

Is it possible that the bug 34429 causes the same problem - uninitialized eDP output after suspend and resume? |

Created attachment 34582 [details] dmesg when DP-1 is plugged in This happens when booting with an external monitor attached to Displayport on ThinkPad T410. After loading nouveau.ko the main display on LVDS-1 switches to hi-res framebuffer (KMS) like during normal boot. But when X is started, it switches to vt7 and then nothing happens - neither is the frame buffer is redrawn anymore, nor the external display is enabled. This is not a lockup, though. I can switch back to vt1 with ctrl-alt-f1, and I can login into the x session by blindly typing username/password (though xdm) or start gtk-demo from vt1. (Same happens if I just start X with "X -wr&" .)
