I hope you can resolve this issue & get EnOS on the system. If you do & want to use it for streaming media these Chrome/Brave extensions may be useful for fullscreen playback:
- ‘Improve YouTube!’
(for YouTube & Videos)
– Automatic fullscreen
– Themes & Dark mode Schedule (also Black theme for oLed)
– Undo the new Sidebar (Description, details, comments)
– frame by frame advance
– way too many to list here
– NB: don’t use the adblock feature, it’s detected by new YT & halts/3-play-limits video playback, rely on Brave adblock instead - New Netflix 1080p
– Play Netflix movies in 1080p in Chrome
– Unlock 5.1 audio where available
– Automatically switch to the highest available bitrate
– more
Maybe you can dig some useful stuff out of this crud too.
Best of luck.
