Bug#498632: nv failing to detect monitor size on DVI-D
I have also just hit this bug. There are, of course, many cards and
monitors nowadays without vga ports. Upstream really need to fix this
urgently if they want to sell nvidia graphics and GPUs. There has to be
an open source driver as well as their closed source version - which
often lags current kernels.
For the record here are some extracts of logs:-
