Public bug reported:

I installed the system with the options 'i915.modeset=0 xforcevesa'.
I only can run LVDS-1 with vesa and i915.modeset=0.
When an external screen is connected on VGA-1, you can only see the desktop on VGA-1. On LVDS-1 is only the backlight working and it looks like a 'blank screen'.

xrandr throws out:
