I can run DotT fine in windowed mode, but I'd like to sit back from my screen a bit. When I toggle the fullscreen mode, the screen goes blank but the sound of the game continues. I can exit fullscreen mode too.

I've tried running in a terminal and logging the output, but all I see is: "Running Day of the Tentacle Remastered".

Is there a way I can debug this further? Or are there well known troubleshooting steps I can try? I understand DotT uses ScummVM, but googling for nvidia/fullscreen/scummvm/etc hasn't helped me much.

Hi! Apologies for not spotting this thread sooner.

Are you still experiencing this problem? I spotted one user with similar sounding experiences, but they were running the first beta of the amdgpu-pro drivers and their issue resolved itself when they upgraded to the second beta after it was released.

There is a logging option covered in the readme. I set it up to mostly only log stuff that's likely to be relevant to crashes, and from what you say, it sounds like the game is still running at some level so we might not get much information there.

If you exit the game after setting it to fullscreen and launch it again, does it behave? (alternatively, you can modify settings.rc before starting the game, which should be in ~/.local/config/doublefine/dott/)

I'll try to keep an eye on this thread, but sadly GOG doesn't give me email notifications of replies so it may slip under my radar. If you aren't able to get anywhere, shoot an email to support@doublefine.com and I'll get word :)
