I did one more test.
I found an analog cable for the second fullhd monitor and connected it via the
DVI-I to D-SUB converter. Both monitors worked well!
So ... You were right. The nouveau driver cannot drive the second digital
output (DVI-I-2), but can drive the analog part of the DVI-I-2 output.
Here's the xrandr output (not sure if it is needed, but .... anyway)
Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 8192 x 8192
DVI-I-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis)
477mm x 268mm
1920x1080 60.0*+ 50.0
1600x1200 60.0
1680x1050 60.0
