XP 12 won't launch on Linux

[Backbone]

I run Steam on Ubuntu 22.04, other games like Factorio works well.
If I launch the game directly from the binary the game starts, but is says that needs to started from steam (I think is a licensing requirement), but if I try to launch the game from Steam it's says for a couple of seconds that's running, nothing happens and returns to the green "Play" button.
I couldn't find any debug or log related to this inconvenient in ./local/share/Steam, I only found some crash dumps but with not a lot of information.

There is a log.txt file in the installation root. Is it a clean install or do you have any plugins installed?

[Backbone]

Thank you for answering!

I don't have the log.txt file, and after reinstalling (just in case) the windows executable versions is being downloaded. In the previous installation Linux binaries were available, even I tried to execute it with "./X-Plane-x86_64" that worked but crashed because Steam was required as I mentioned.
Answering your question about installation, is a clean and plain installation, only some DLC scenarios. I'll try to get back the Linux binaries.
Any further help will be appreciated.

Well, the Windows binaries is because I was modifying for testing purposes the compatibility . After restoring to default values I have the Linux binaries again and Log.txt file.

If helps someone, I was finally able to run the game in a weird way from which I have not explanation.
What I did, exits Steam and execute the game directly from the terminal with this command:

steam "steam://rungameid/2014780"

This starts again steam and the game. After that I can execute again the game from the GUI.
Weird? yes
Why? no idea
Solves the problem? I think yes, at least I'm able to play.

[Backbone]

Well, new Info, following this link solved the problem.

Basically I modified the desktop link that executes steam.
The file is /usr/share/applications/steam.desktop and modified this value which by default true:

PrefersNonDefaultGPU=false

Hope that helps someone else.

It does help. I haven't seen this one before. I think its because you are using a APU (CPU/GPU in one).
