[Bug 1712356] Re: Update breaks graphical system when X/Wayland is on vt[1-6]

[Daniel van Vugt]

Is this a serious problem? What's not safe?

We used to run Mir servers on arbitrary VTs that already had consoles on
them and never had a problem. You get a GUI while the server is running
and it returns to a tty upon exit.

Title:
  Update breaks graphical system when X/Wayland is on vt[1-6]

Status in console-setup package in Ubuntu:
  New

Bug description:
  The update of console-setup in artful-release that just happened
  triggered a bug-

  the postinst calls `setupcon --force' if the foreground console is
  tty1-6. This is not safe any more given that gnome-shell runs on 2.

  We can update this check to ask logind if the foreground console
  corresponds to a tty session, and only do setupcon --force if it does.
