For me the laptop screen on LVDS-1 works, but another screen only works when connected to VGA-1. I can connect it to DVI-D-1 and it is detected correctly and I can activate it using xrandr (and move the mouse there) - but the monitor will only go into power save. With VGA-1 everything works as expected. On windows the second monitor also works via DVI-D-1, so it's not a hardware limitation (didn't test the nvidia blob). I also think these bugs might be related: https://bugs.freedesktop.org/show_bug.cgi?id=30589 https://bugs.freedesktop.org/show_bug.cgi?id=43668 (I did test with "nouveau.perflvl_wr=7777 nouveau.perflvl=2", but I only get screen corruption that way - also not the 2 instead of 3, since there doesn't seem to be a perflvl 3 on my card).
