This problem started 3 weeks ago. When I login and do not immediately start a YouTube video or a call, I get a black screen with no input working anymore and also not even the power button letting me turn off my machine. Every time this happens I have to turn of my power supply.
So my workaround has been to play a mute video the entire time. I also made sure to uninstall all Gnome Extensions and swapped out the video card and use the Nouveau drivers. Nothing has worked so far.
Thank you so much for help.
