Display goes black, Kernel 5.9 & disconnecting HDMI

Support Graphics & Display

Hi Kessel,
good to know im not the only ony going crazy with this issue, wich now happens for me under Manjaro Gnome as well, but i may have found something!

https://www.linuxquestions.org/questions/slackware-14/kernel-5-10-4-i915-and-dual-screen-freeze-on-intel-gpu-4175687776/page4.html

by adding into “/etc/modprobe.d/snd_hda.conf” this line:
options snd_hda_codec_hdmi enable_silent_stream=N

i can now use all kernels up to the last RC, with dual setup, switch on and off screens and avreceiver, no lock up in the past 4 days.

i still have some weird behavior like screens not connecting until the avreceiver is not switched on again, but no lock up forcing me to hard reset.

maybe this fix can solve your problem too.
