Hi
we have "HP ProOne 600 G2 21.5-in Touch AiO" PC, equipped with "Intel
HD Graphics 530" graphics card
We are using debian stretch (testing) based linux distro named pardus.
But we have observed the same condition under ubuntu 16.04 LTS.
our problem is: screen divided half horizontally.
Our screen is splitted into equal 2 parts horizontally from the middle.
her is the screenshot: http://bit.ly/2mRvf3s
if we use "nomodeset" kernel parameter at the grub startup, we get one
screen but this time we are locked to 1024x768 screen resolution. xrandr
only reports this resolution. and we could not add newmode.
I have included some diagnostics below.
Thanks for your help
