session Run the configured screensaver payload for one monitor.
|

|

The default payload is an mpv-rendered lavfi animation. You can override the
|
||||
source with HYPR_SCREENSAVER_SOURCE, for example:
|
||||
By default, start chooses a random media file from:
|
||||
/var/lib/syncthing/sync/Screensaver/use
|
||||
|
||||
Populate that directory with symlinks to generated screensaver loops you want
|
||||
in rotation. You can override the source with HYPR_SCREENSAVER_SOURCE, for
|
||||
example:
|
||||
HYPR_SCREENSAVER_SOURCE='/path/to/video.mp4'
|
||||
HYPR_SCREENSAVER_SOURCE='av://lavfi:mandelbrot=s=2560x1440:r=60'
|
||||
|
||||
You can also override the rotation directory:
|
||||
HYPR_SCREENSAVER_USE_DIR='/path/to/use'
|
||||
|
||||
HDR handling defaults to matching Hyprland's monitor color-management preset.
|
||||
Only monitors with preset "hdr" or "hdredid" get HDR colorspace hints. Override
|
||||
with:

||||
HYPR_SCREENSAVER_HDR_MODE=auto
|
||||
HYPR_SCREENSAVER_HDR_MODE=sdr
|
