If you are trying to run MatterControl 2.19 (I believe this impacts multiple versions) on Linux and the application crashes with an error about not being able to find Visual Basic, then it may be due to color, depth, or FSAA settings.

For example, this error:

exception inside UnhandledException handler: (null) assembly:/usr/lib/mono/4.5/mscorlib.dll type:FileNotFoundException member:(null)

[ERROR] FATAL UNHANDLED EXCEPTION: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualBasic, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

Change the lines in this file (/usr/lib/mattercontrol/appsettings.json )to use 4 FSAA samples or 0 (zero). It could also be related to color depth, but unless you are running on an old machine with an old version of Linux, then it is probably going to be the anti-aliasing option.

{
  "Agg": {
    "GraphicsMode": {
      "Color": 32,
      "Depth": 24,
      "FSAASamples": 4
    },
    "ProviderTypes": {
      "DialogProvider": "MatterHackers.Agg.Platform.GtkFileDialogProvider, agg_platform_gtk"
    }
  },
  "MatterControl": {
    "Slicer": {
      "Debug": false
    }
  }
}

I am really, really late in finding this out (I’m looking at you Jared), but you can still buy World of Goo and pay whatever you want for the title during their birthday sale. It’s an experiment of sorts, and the data they collected is not terribly surprising (I’ve seen data collected before which indicated purchasers went “on the cheap” because that’s “all they could afford at the time”), but if you think there is money to be made using this model, then it’s certainly worth it to go whole hog and put your data where your mouth is, or your money where your data is, or whatever.
