Hello Adrian, not sure what happened, but something changed the last few days, maybe due to an update. (Latest update was small: libpgm-5.2-0 libwxbase3.0-0v5 libwxgtk3.0-0v5 libzmq5 orage. I'm not sure if I had more updates in the meantime) I've had the described bug, but now I get the same error messages as you without crashing X on display :0. Before sending this bug report, I did further tests in virtualbox. The bug still persists in VirtualBox with guest additions installed. It is gone in virtualbox _without_ guest additions, and it does not happen on my host machine anymore. > You are basically trying to shoot yourself into the foot and you are > surprised that you get hit. :) Nice said. Those command has been possible in debian jessie, stretch behaves different. For example, in jessie I can use vt8...vt12, but not in stretch. But that is another story ... Not sure if this is related: Now, if running several X servers on tty1...tty6 with xinit xterm -- :1 vt1 ... xinit xterm -- :6 vt6 my desktop session (xfce) on display :0 returns to lightdm login after some switching between ttys.
