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.

It sounds like you have a graphics problem that may crash whatever
display program you're using.  You probably have to resolve the
graphics support, first.

You probably should say what you're trying to display.  Is all your
data PDF, or is it from a text source you render in some kind of
fashion to suit whatever display program you're using?

If you make a JPEG/PNG/GIF/etc of your text, you could use the
screensaver to run your display.  Or if you want to script it, rather
than let the screensaver show randomly prepared graphics, there's a
variety of commands that can be used.

Likewise for displaying PDFs, if that's what you want.  Using scripts
to load the PDF viewer, commands to wait, exit the viewer, and load
another one, rinse, lather, repeat.

I like an ancient program called xloadimage.  It has a delay this
might come close "xloadimage -global -delay <seconds> <imagenames>" to
doing what you are asking for.

You might need to put a bash wrapper to restart it once all of the
images have been displayed once.

Yes, for now, I would say that it crashes more when I have no
mouse+keyboard connected. So for now it seems to work with a keyboard
and a mouse connected.

Yes only PDF.

Yes that's what I did infinite loop starting impressive.

In that case, as a simple test, I'd try using Xorg instead of Wayland. 
That *may* narrow it down to a Wayland or the particular graphic
chipsets driver problem.

Depending on what you've installed, it's available as a login option
*between* entering your username and password.

If you've set up an auto-login, you should still be able to do that by
manually logging out, and manually logging in making the selection. 
Your next boot-up and auto-login ought to use the settings you just
made.

Hello,

For the record, this seems to be solved by a BIOS update.
The machine is a GIGABYTE GB-BXBT-1900.
Before update, it craches after 1 hour to few hours(not more than 4).
After BIOS update, for now it didn't crashes for more than one day.

Alexis.
