[drm] HPD interrupt storm

**ubumonk** · October 11th, 2019

hello

I have problems with a new monitor and HDMI connection to the laptop, when I connect the external monitor AOC 22BH1 21.5" no signal, can be a problem with HD intel graphics

Hardware > Lenovo Laptop V110 15,4"

External monitor > AOC 22BH1 21.5"

OS > Xubuntu 16.04

kernel version > 4.15.0-65-generic

kernel.log >
drm] HPD interrupt storm detected on connector HDMI-A-1: switching from hotplug detection to polling

glxinfo | grep "OpenGL version" >
OpenGL version string: 3.0 Mesa 18.0.5

lspci |grep VGA >
VGA compatible controller: Intel Corporation HD Graphics 520 (rev 0a)

I have installed the latest intel drivers via > intel-graphics-update-tool_2.0.2_amd64.deb, intel you have abandoned them long ago

Any solution?

Thank you!

Upgraded Xenial to Bionic, installed the latest kernel 5.3.6.....not working

Today install the latest open graphics drivers for Bionic without success, probably another person can be useful
