Hi,
I just got the game and when I go to run it, it starts and then just crashes without a screen popping up or anything. I've tried it on Gnome Wayland and Gnome Xorg
OS: Fedora 26
CPU: Ryzen 5 1600
GPU: Radeon R9 270X
Some of the errors from the log...
ERROR: ld.so: object '/home/$USER/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.
process 10148: arguments to dbus_connection_unref() were incorrect, assertion "connection->generation == _dbus_current_generation" failed in file ../../dbus/dbus-connection.c line 2794.
This is normally a bug in some application using the D-Bus library.
UPDATE: While I can't test this with Avorion I've had similar issues with another game (Dwarfcorp) and it seems a fix was found.
This fix was tested on Fedora 27
