Created attachment 113732 [details] dmesg with nouveau.debug=debug drm.debug=0xe Hi, adding this patch on top of linux-3.19 or tip of http://cgit.freedesktop.org/~darktama/nouveau is enough to get a GM206 / GTX 960 to get 'modprove nouveau' to work and getting output on a VGA monitor attached to the DVI-I port. However trying the same with a HDMI monitor attached to the hdmi port does not work. Attached is dmesg output with extra debugging enabled + a 2nd file with debug level=trace enabled. I have also sent an mmiotrace of that hdmi use-case by mail.

One observation about the mmiotrace... grepping for PDISPLAY (and MARK), I see the following sequence after the replug happens. I don't know of anything we have any code to reproduce something like that. It also looks like the blob is using PDAEMON to do a *lot* more stuff now...

This patch just sent to the list fixes that for me: http://lists.freedesktop.org/archives/nouveau/2015-February/020143.html With that attached HDMI monitor is detected as connected and lights up.
That bug was fixed in 4.0
