D_r_B: Same problem here, on Ubuntu 20.04.
The AI name window stay behind a bit after validating, just as the station name window. When validating this one, the game come back to the main menu, with the station name window staying in front of it. Impossible to reach the game.
I also have no sound at all. :/
Devs must be busy with the launch, but let's hope we won't have to wait too long for the patch on GOG.
Defective_Soul: For sound check game executable with LDD (open console, cd in game's directory and type ldd Starmancer.x86_64)
If you see any "missing" libs then check wich package provide them and install them
If they already installed make downgrade-link or use LD_PRELOAD to provide non-installed version of libraries
Oh, true that i still don't have the reflex to check that, thanks! Unfortunately it seems all dependencies are ok, so that may be something else.
Anyway, i could play this game without sound as long as it is not corrected, but first i'd love to be able to play the game i just bought.. ;)
Still, thanks for the answer!
