Not sure what distro you’re using but try the liquirox kernel. I did that one time on a really stubborn laptop and managed to get both the HDMI and the suspend feature working.
Using mainline or something to ensure I’m up to date on the latest kernel has never solved a single issue in my entire history of trying but using liquirox worked one time.
This. When YouTube finally succeeds in making it impossible for anyone to use their website without watching ads, they probably still won’t succeed in preventing people from downloading for offline viewing. When this happens I’m going to invest in making scripts that autodownload stuff ahead of time and I’ll only watch whatever videos are in my home network.
Im not watching their brainwash bullshit ass propaganda. I’ll find other stuff to do for entertainment before I give in to ads.
