Hello,

with the latest drm-intel-nightly (commit id
4fa23142a15526f4a4b5df61f26eacdd558a849a)

I see the monitor in xrandr only if it is connected at boot time:

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
eDP1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 309mm x
174mm

   800x600       60.32  
   640x480       60.00  


If I start the laptop without the monitor attached xrandr shows only:

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
eDP1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 309mm x
174mm
   1600x900      59.99 +
   1440x900      59.89  
   1360x768      59.80    59.96  
   1152x864      60.00  
   1024x768      60.00* 
   800x600       60.32    56.25  
   640x480       59.94  
DP1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)

A quick search in dmesg and /var/log/Xorg.0.log did not show
anomalies.

Let me know if you need further information.
