Hoho... i have a breakthrough. I think the grub makes problems. I tried to reproduce this issue on each step: bios, grub and linux. And results are fallowing: - bios (called with Fn+F2), no problems. I can normally switch between screen (Fn+F8) - grub. first problems. If bios was switched to eDP, then grub can switch (Fn+F8) between VGA and eDP. If bios was switched to VGA, then grub knows only VGA and F8 switch goes after some blinking back to VGA. If i plug VGA display after grub was loaded then, i can switch between displays. In both situations, if two displays are recognized by grub, then image on vga screen is not clean, with some kind of distortions. - linux. completely depends on grub. - windows. can some how recover after grub.
