running

GNU/Linux

My System turns reproducable into a piece of brick every 2nd boot when
switching to inteldrmfb from VESA ?VGA? or so. 
Sometimes the CLI Screen gets a bit cluttered or blacks out or just heats up
the room. 

I also noticed: 
KiCAD schematics gets cluttered with mousecross until refresh. 
I can not use a secondary display by hdmi and xrandr. 

I tried to find some loggings but since it happens during bootup i did not find
anything to investigate further details. 

If i can support to investigate / fix the annoying shit please let me know what
/ how to do as i really would like to use my big stationary screen for cad.   

Sincerely Reiner
