Hello,
Lenovo T430 laptop with intel/nvidia hybrid graphics, but optimus is disabled in BIOS, and only the Nvidia discreet GPU is enabled:
$ lspci | grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [Quadro NVS 5400M] (rev a1)
I boot up the laptop with only using the laptop internal LVDS panel, and when in X session, I connect DVI cable to the docking station. xrandr now correctly shows DP2 as connected, and when I enable the DVI display, I get these nouveau errors in the kernel dmesg:

Should I file a freedesktop bug about this?
DVI monitor output actually gets enabled, and I can see the desktop there, but both the LVDS display and the DVI display are all messed up.
For example moving a window around leaves traces of other window contents, and the background image gets replaced with all kinds of corrupted patterns, so graphics looks quite weird and corrupted on both displays.
Switching back to only using the internal LVDS (disabling DVI/DP2 output) fixes the graphics corruptions.
