Startx as a regular user

note that even if you manage to somehow start an Xorg session on an UbuntuCore install through hackery, your snaps will (and wont) be able to talk to the display. this would require that the x11 snap interface is available in “snap interfaces” and that your snap would connect to it … since the x11 protocol is insecure and allows snaps to break out of confinement we will not add it to the UbuntuCore images.

In this particular case everything is in a single snap, the X11 server and the application which talks to it.

@ogra

to run graphical kiosk applications on a core IoT system you can use the mir-kiosk snap and have your app talk to it via the provided interface (i assume there will also be a wayland-kiosk snap at some point to allow standalone fullscreen apps to run on wayland)

Xorg is definitely nothing we plan to support on UbuntuCore.

X11 is the way to go in this case, trust me.

I’m trying to start X server as a regular user. I’ve created a snap command and I execute into it as my current user in the device (a Rpi3, btw), but I cannot since I hit this problem:

EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied)

Why are you trying at all to run X11 as a different user than root?
