You should read the article. It has a section specifically on using a zram fallback device and how its performance compares to a similar zswap setup.

I use this in a cronjob to turn a raspberry pi screen off at night and back on in the morning:

wlr-randr --output "HDMI-A-1" --off

wlr-randr --output "HDMI-A-1" --on

I’ve also go this environment variable set but I don’t know if it is needed outside of cron:

XDG_RUNTIME_DIR=/run/user/1000

Probably need to update. With plain yt-dlp you just run “yt-dlp -U”
