Bug#812791: xserver-xorg-core: Kills DM controlled session when opening X from another tty
Package: xserver-xorg-core
Version: 2:1.17.3-2
Severity: normal
Dear Maintainers,
I am having a strange problem apparently starting with 2:1.17.2-3.
I often have a display-manager controlled X session for one user and open
another X session in a free tty for a different user with startx.
This has been working for a long time. However, after a recent testing
upgrade including xserver-xorg-core 2:1.17.2-3 this started to fail
(failure happened before in a sid box, but there were more upgrades to
look when trying to locate which change might be responsible).
When I have a display-mamager controlled X session and, without leaving the
session, switch to a free tty, login as another user and start an X session
with startx original X session gets killed and I am sent to DM greeter.
With 2:1.17.2-3 I was not even allowed to re-open a DM controlled session
even if I close first the startx created X session. Seems that this is no
longer happening and I can now re-enter but after some session switch
original new DM controlled session gets killed.
Tried with xdm, wdm and lightdm as DM and xfce4, icewm and openbox as
sessions opened from the DM. With xfce4 session killing is faster, but it
is killed anyway with the other.
Tried with xserver-xorg-legacy and /etc/X11/Xwrapper.config containing
needs_root_rights=yes
allowed_users=console
No luck, problem persists.
No problem if I create different X sessions with startx from different ttys.
If I downgrade xserver-xorg stuff to versions in wheezy/stable, problem
seems to disappear.
Also, note that I am using sysvinit in this box.
No apparent errors in usual log files. auth.log just shows it as a normal
logout.
