Hello, I tried to find the appropriate place to file a bug report. On my dell latitude e5440 when I undock and redock I am unable to re-activate both monitors using xrandr. I'm using linux kernel 4.4.5 and the i915 driver, and also could not find the appropriate section to file a bug report. Can you appoint me to the appropriate section on the bug reporting page to file the report against?
