Bummer, but hey, some progress at least
. Sadly I do not know much about Odroid. Honestly, your thread was the first time I heard about it. It is an arm board, isn't it? And you are running Ubuntu.
Maybe it would help if I tried to get it running on my Pi4 running Ubuntu server or smth?
The config file not found error you can ignore. After you get it starting correctly it will create a config file. I did not experience this pixel modifier error however, things that I would try:
1) sudo attract (if there even is something like sudo on your os)
2) If you didn't already, compile smfl-pi and attractmode with the openGLes flags in addition to DRM. I think ES is for embedded systems, which your odroid should be.
Edit: you also have to use the USE_GLES=1 option when running sudo make install.
