Public bug reported:

Binary package hint: xorg

Trying to connect my laptop computer to an external monitor. The screen
is simply duplicated and I can't change this via Monitor Preferences.

When opening the System -> Preferences -> Monitor, the monitor of my
laptop is unknown, 'Same image' is greyed out, refresh rate is zero, and
I only have the choice for one resolution.

With xrandr the attached monitor is not detected:

xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768        0.0* 

When booting with editing grub: i915.modeset=0, the Monitor Preferences
gives more resolutions, but no image appears on attached monitor.
