I'm using my HP Pro X2 612 Laptop with dual monitor. This works fine in Grub & Windows 8.1
But as soon as I boot in Ubuntu 15.10, my monitor, which is connected via DP, begins to flicker (here the video I made).
I'm using a DP->DVI cable and tried it also with an DP->Hdmi cable, both with the same result in Ubuntu.
Do you have any suggestions or is this maybe a known problem?
Greetings, nostalgamos
