FIX: Game Not Starting in Linux with 2 Graphics Cards

[SimonC4]

If the game is not starting for you and you are running Linux and have multiple graphics cards, then this fix might help you out.

1. Download lwjgl.jar from here[github.com].
   
2. Open ~/.steam/steam/steamapps/common/Destination Sol/libs
   
3. Replace lwjgl-2.9.2.jar with the jar file downloaded in step 1. Make sure the new file is named correctly.

You should be able to start your game from within Steam.

Hello! I just ran into that problem on my notebook (desktop Linux worked fine, lovely game!) and tried what was described above. Sadly, that didn't work. I also created a settings.ini by copying and adjusting the one that was created on my desktop Linux (no settings.ini was created by launching the game on my notebook), which still did not change anything. Meanwhile, there was no log output whatsoever on the console other than the usual Steam stuff.

I'm going to give it a try with the Github version when I can, but I thought I'd let you know.


[edit] I just started the game using sol.sh in the Steam directory and finally got some log output:

The German stuff at the beginning translates to "Can't open the shared object file: file or directory not found".

When I run the game with my installed JRE (Oracle Java 8), the output looks like this:

Thanks for the report! So just to be sure what you're doing, you've replaced the LWJGL file with the workaround, but that then triggers an issue with an audio library file? I've linked to here on the related GitHub issue so we can look at it sometime.

Probably we need to sort out the LWJGL/LibGDX situation so we don't need the workaround, and see if this still happens. That may take a little bit though.

What version of linux are you using?

I'm fairly certain that in the bottom output you posted the cause of this issue is the two graphics cards. Could try the fix in the original post and try running with your local java again and posting the output.

You could also try opening a terminal and running sol64.sh from the Steam folder. This launches the game with the 64-bit java.

I moved further discussion of my particular problem over to GitHub[github.com].
