Looking for slide show softwares on autonomous machine

[jeandet]

Hello all,

In my lab I installed a machine connected to a big screen on which we
present news. 
This machine is supposed to be as much autonomous as possible. So I
chose impressive as PDF player but it seems that after few hours it
crashes because of a fatal error in XWayland.
Starting it from gnome + Xorg doesn't change anything.

I'm running Fedora 27+Gnome+Wayland.

So my question is, anyone knows others softwares I can start from bash
with options to put in full screen plus time  between slides?...
Gnome-document looks good but it doesn't seems to be possible to do
that from bash.

Best regards,
Alexis.
