I'm having trouble running the linux version. The issue that I'm having is that the 64-bit version just displays a black screen and then crashes, the 32 bit version seems to work fine but I think I might be experiencing some minor optimization issues with the 32-bit version. I read the troubleshooting guide but the only thing it seems to have is a link to a forum post for something completely unrelated that also seems to only work on Debian. I have Ubuntu and the terminal commands the post states to use don't work, the first one doesn't work because deb isn't a valid command on Ubuntu and gives me an error message saying that I don't have permissions and if I add sudo to give extra permissions, it states that "jessie-backports" isn't valid because it's not available in the sources.
