        I manually set the TMOUT variable to 0 to disable it, and it still happens. So that is not what is being used.

          Tried disabling AppArmor, but that did nothing.

              Try this command first to bypass bash settings

              ssh -t <host> dash

                Using ZSH is what I am doing, works fine, too.

                  Pretty confident that it is none of those. They are all vanilla.

                      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

                                        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.
