Hi, when I’m not emulating on my pi, I’d love to run a screen saver

Currently, what I do is
– Press F4
– Type startx
– Type feh -F -Z -z -Y -D5 -p /home/pi/slideshow

Is there a way to automate this and kick it off using the controllers directly from emulation station?

If not, (and I’m pretty new at linux) is there a way to write a shell script that start xwindows then starts FEH? I tried typing both commands in a shell but I can’t seem to start x then start an app
