I have dell optiplex 9020 with i7 - 4770 with integrated graphics(hd 4600), ubuntu 14.04 and two display port o/p on mother board connected to 2 dell monitors, but only one display works while another indicate no signal from source. Prior upgrading to 14.04 from 12.04 dual display worked in same configuration perfectly.
Hi - if this regression occurred simply by upgrading from ubuntu 12.04 to 14.04, and wasn't
triggered by installing the updated driver from this site (and installing said driver doesn't
fix things for you) then you might have more luck reporting the bug directly to ubuntu:
It sounds like a regression in 14.04 frm what you've said so far.
If it was triggered by the driver from this site, do let us know and we'll look into it further.
