Intel HD-Grafik 4400 black flicker on external monitor

Asked by Bastian on 2018-07-29

I'm running a fresh Ubuntu 18.04 on a laptop that has an HD 4400 graphics card. It all works fine on the laptop's own screen, however, when hooking up an additional (1920x1200) screen via DisplayPort--HDMI I get a black flickering at irregular time intervals on that screen. The flickers usually occur every two seconds and appear to be correlated with how much is goig on on the screen.

The Additional Drivers tab in the Software & Updates window says "No additional driver availale."

Any clue on how to resolve this issue? Thanks!

Have you tried a different display and a different cable to test if they are at fault?

Can you help with this problem?
