Hi all:

My Dell laptop has a Intel Broadwell graphics card and an hdmi 
connection. I'm running Ubuntu 14.04 LTS. When I connect an external 
monitor to the hdmi, the system freezes and I have to do a reboot. I 
have pasted the output from certain commands below. Is there a driver or 
a ppa from Dell I can install to solved this? I need to connect the 
laptop to an external projector to do presentations.
