Hello,
Any comments? Should I provide more logs, or try something I didn't try yet?
I just tried Linux kernel 3.9.2, and it has the same kind of graphics corruption when enabling second output on nouveau adapter.
dmesg errors from 3.9.2:

Hello,

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.
