Linux Login Issues

Fri Jan 10, 2020 12:12 am

Hey guys,

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:

root@chris-iMac:/opt/Simplify3D-4.1.2# ./Simplify3D
Qt: Session management error: None of the authentication protocols specified are supported

[1]+ Stopped ./Simplify3D

Any ideas what's going on? Like I said, totally new here, so there might just be something I'm missing. Thanks!

The easiest way to open Simplify3D on your Linux machine is to open a Terminal and cd to the installation directory. Then type the following command:

sudo ./

This ensures that Simplify3D will be able to correctly access the serial port for your printer and will have the necessary permissions for saving your application preferences.
