can't use it on more than one screen

[carepollo]

I configure it on my primary monitor and it works fine, but I want that configuration applied to monitor 2 and 3 as well but it just stays black.

maybe a duplicate of #36

Currently you need to set and configure the wallpaper on each monitor manually and it should work.

If that is not the case please do the following:

1. Run journalctl -f > journal.txt and sudo dmesg -wHT > dmesg.txt in separate terminals
2. While both commands are running switch from the Image wallpaper plugin to video wallpaper and reproduce the issue
3. Then stop both commands
4. Get your system information from kinfo
5. Run lspci -k | grep -EA3 'VGA|3D|Display' > lspci.txt

Then share the outputs/files here

If the wallpaper is working on each monitor after configuring manually

Note that currently when using this wallpaper on multiple screens:

Playback syncing is not ensured

If you apply the same configuration with Filter: Only check for windows in active screen unchecked on all instances of the wallpaper, videos will stay synced when Plasma starts but that is not warranted because they are effectively two different players, so videos will de-sync if for example a monitor is disconnected.

Will use more system resources

Since each wallpaper runs separately, Plasma will use as much ram as Video wallpaper instances are running and more GPU or CPU if hardware accelerated video decoding is not enabled in your system.
