<div>
<pre>I have a brand new computer with an NVE7-based card (GT740); the card has three
physical outputs, 1 each DVI, HDMI, and VGA. I have two monitors. If I
connect one to the DVI and one to the VGA port, or if I just connect one
monitor to the DVI port, it boots successfully. But if I connect one monitor
to the DVI port and the other to the HDMI port (using an HDMI-to-DVI adapter
cable), the GPU and/or the kernel component of the nouveau driver crash
immediately upon switching the console to nouveaufb. (This happens before the
X server starts.) Both monitors go into power save, the keyboard is
unresponsive, and there is a flood of nouveau-related errors in the kernel log.
Later, X *thinks* it has started successfully -- there's nothing that looks
like an error to me in xorg.0.log -- but the monitors do not wake up and the
keyboard remains unresponsive. I can, however, ssh into the computer.
(It now occurs to me to try connecting just one monitor to HDMI. I will do
that after submitting this bug report.)
I will attach dmesg and xorg logs from both successful and unsuccessful boots.
Please let me know if any additional information is required.
I'm using distribution packages of everything involved, from Debian unstable as
of, er, today. The Nvidia proprietary drivers have never been installed.
Version information gleaned from xorg.log:

Current version of pixman: 0.32.6
NOUVEAU driver Date: Thu Aug 28 03:57:48 2014 +0200
