Hi,
Im using a HP 14s dq laptop with intel 630 graphics.
I've tried both the mode setting and xserver-xorg-video-intel drivers,
both result in the same 2-second black screen blips. The happens
frequently using chrome, and always when using the gnome screenshot
utility. Also, during boot teh screen flickers between black screen and
boot splash a lot.
setting nomodeset as a grub parameter stops the flickering, but is not a
feasible solution as brightness can no longer be set.
kind regards,
