I have tried launching the following games from GOG that are built using Unity:
- Enter the Gungeon
- Hollow Knight
- TIS 100
- Tyranny Commander Edition
All of them fail to launch, with the following output in the terminal if manually launched:
Running CAYNE Set current directory to /home/shadow53/.goggames/CAYNE/game Found path: /home/shadow53/.goggames/CAYNE/game/cayne.x86_64 Mono path = '/home/shadow53/.goggames/CAYNE/game/cayne_Data/Managed' Mono path = '/home/shadow53/.goggames/CAYNE/game/cayne_Data/Mono' Mono config path = '/home/shadow53/.goggames/CAYNE/game/cayne_Data/Mono/etc' displaymanager : xrandr version warning. 1.5 client has 3 screens displaymanager screen (0)(eDP-1-1): 1366 x 768 Using libudev for joystick management Importing game controller configs /home/shadow53/.goggames/CAYNE/start.sh: line 16: 2957 Segmentation fault ./"cayne.x86_64"
Games not made using Unity/Mono launch and work normally. The only non-default setting chosen at install time is to install games to a hidden directory ~/.goggames.
I've tried executing with and without LSI (using lsi-exec and disabling it through the options window, respectively) and they don't launch in either case.
I am using an Optimus laptop with the Nvidia drivers installed, up-to-date as of posting. An old Intel-only desktop (Core 2) can open TIS 100 normally. This makes me think this may be an issue related to Optimus, but I don't know where to go from there.
If someone starts figuring out a fix, CAYNE is free on GOG, which should help with testing the fix. I am also willing to help how I can.
