Bug#834270: xorg: logging out of shell on vt2 crashes X on vt1
Package: xorg
Version: 1:7.7+16
Severity: normal
With a machine running more or less current stretch the following steps
will crash X on VT1 every time:
- log in to VT1
- launch X via startx (.xsession launches a few things, and then xmonad)
- Ctrl-Alt-F2
- log in as another user on VT2
- launch X via startx (.xsession launches xmonad)
- quit xmonad, which quits the xsession
- exit the VT2 shell
At that point, the X instance on VT1 will crash with something like this
in the log:
[ 248.046] (II) AIGLX: Suspending AIGLX clients for VT switch
[ 248.046] (II) AIGLX: Resuming AIGLX clients after VT switch
[ 248.047] (EE) modeset(0): failed to set mode: Permission denied
[ 248.047] (EE)
Fatal server error:
[ 248.047] (EE) EnterVT failed for screen 0
[ 248.047] (EE)
[ 248.047] (EE)
Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.
[ 248.047] (EE) Please also check the log file at "/home/rlb/.local/share/xorg/Xorg.0.log" for additional information.

[ 248.047] (II) AIGLX: Suspending AIGLX clients for VT switch
[ 248.207] (EE) Server terminated with error (1). Closing log file.
I don't upgrade to current stretch regularly, but I suspect this may
have started happening sometime in stretch in the past month or two.
