Hi.

I purchased Costume Quest 2 on the Haloween Sale and downloaded and installed the Linux version on Ubuntu 20.04. However, when launching the game, from the Ubuntu launcher or by running ./start.sh, I just get a black screen and no sound. Normal key combinations such as windows key, alt+tab or ctrl+alt+del are blocked and do not work. I know that the computer isn't locked up because the ctrl+alt+f1 key combination still does work, but then I have to reboot, as if I just log in again I get back to the locked black screen.

Did anyone manage to get the Linux version running? If so, did you have to install any dependencies or libraries that the installation process did not include?

I have previously installed Linux versions of games from GoG and usually they work (e.g. Wonder Boy, Pilgrims, Rogue Legacy, etc.) without any issue.

I did not find a complete solution yet, even after contacting GoG support. But found myself a workaround that at least makes the game work.

Steps:

1. open the "game/screen.dat" file in a text editor (gedit is fine);
2. change the line "fullscreen = true" to "fullscreen = false";
3. change the line "width = 0" to "width = 1920" or whatever your screen resolution is;
4. change the line "height = 0" to "height = 1080" or whatever your screen resolution is;
5. change the line "refreshrate = 0" to "refreshrate = 60";
6. save;
7. launch the game (run ./start.sh or GoG's shortcut).

The game will work just fine, but in windowed mode.

It's a functioning workaround, but I would still like to run it full screen if possible.
