FWIW: I found this bug report last July by searching for the exact same error message OP has. I get it when I try to log out of an Openbox session .
The command openbox --exit shuts down the openbox session as expected but instead of a lightdm/lightdm-gtk-greeter gui login screen as usual, x is shutdown and I get dumped to tty 7, already logged in as root, judging by the prompt. Tty 7 is where my x normally runs. So x has shutdown but login fails to start. Nothing I type appears on the monitor. The last output on tty 7 is: Bash: Cannot set terminal process group (1015): Inappropriate ioctl for device Bash: No job control in this shell The only key combinations I've found to elicit any response are: Cntrl-Alt-Fn where n is any digit in the range 1-6, inclusive, to which it responds normally, switching to the indicated tty. and Cntrl-Alt-Del which causes a normal reboot. I can switch to one of the other ttys and use it normally, including starting x and logging in graphically, but if I log out, the same thing happens again, and now I have another unresponsive tty. Reinhard Karcher's observation about su holds for me to: me@hal:~$ su - -c bash Password: bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell root@hal:~# Strictly, I'm running the Debian-derived Ubuntu 14.04 LTS installed from the mini-iso with none of the bling, plus xorg, openbox & thunar and such, rather than Debian per se. But I believe we use the same login package unmodified and this certainly appears to be a bug we inherited from Debian, so I figured this info is more likely to be useful here alongside the similar accounts than anywhere else. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
