      @IRJ brand new users have the issue, too.

      Doesn't bash have a global default config that applies to all users?

          It has one, yes. But it's vanilla. And even removing it, no change.

            Yup, removed both of those, didn't change anything.

              I see this issue with Graphics card drivers. I would start by upgrading the video card drivers even if it means removing and installing again the package.

                If I use zsh, I'm good. If I enter BASH from zsh, I get kicked out after several seconds. Definitely is something to do with BASH.

                Stupid tryout: use bash and then enter zsh before being kicked out. Still out?
                To understand if it is the firing of bash itself or the stay in bash...

                    Oh wow, great point, the graphic driver could be crashing, causing a remote disconnect. Nice

                      Removing GUI could quickly verify this

                        How do Runtime levels work? Could he remote in at that GUIless runtime level 3 or w/e?

                          No, the underlying bash remains until the ZSH closes. Same as if you were running top from it, for example.

                            Maybe, there is definitely lots of extra code in there, but the connection is via SSH only, so in theory the GUI could crash and never impact us.

                              That's what we are doing.

                                The problem with removing them is that it is a CUDA processing server.

                                  Are the lower runtimes essentially the equivalent to Windows Safemode?
                                  Edit: Except I'm sure the Linux end is significantly more robust since Safemode is so damned restricted.

                                    What happens if you connect to the VM's console and log in via the terminal (not the gui) ?

                                    What about running the shell from within MeshCentral -- do you still get disconnected that way?

                                      Kind of, yes. Mode 3 is just the "normal" non-GUI mode. Some modes are for custom stuff. You can customize any mode, though, if you want.

                                        We didn't build the server, it's not virtualized - likely because it is used as a CUDA system and is older.

                                          Does that stay connected normally?

                                            Once you hit "CONNECT" it will stay connected until you type exit or logoff enough times.
