SUPER Linux newbie here. Running an old mac that I installed Ubuntu on solely as my 3d printing computer. Trying to get Simplify 3D up and running on it, and I think I'm so close but I've been stumped. I installed it (In the directory shown in my terminal copy paste below) and it will run okay (either from the terminal or from the directory) . However as soon as I try to login with my account, the login screen just disappears, and nothing happens. When I run it in Terminal, this is what it looks like:
Qt: Session management error: None of the authentication protocols specified are supported
+ Stopped ./Simplify3D
Any ideas what's going on? Like I said, totally new here, so there might just be something I'm missing. Thanks!
