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
