Bug#564530: xorg: Xorg crashes when a second session is launched
Package: xorg
Version: 1:7.5+1
Severity: normal
When using KDE, the first X session attached to vt7 works just fine.
But then, when I want to launch a second KDE/Xorg sessions on vt8 using
(K / Quit / Switch user / Start New Session) the screen flickers but
instead of presenting a second kdm to log on another user, it falls back
on vt7 (first session) with a lock screen.
When I look on the log file for 2nd session, here is what I got
/var/log/Xorg.1.log :

this happened right after the installation of Xorg 7.5
and if I reinstall xorg 7.4 everything returns back to normal (I can
start 2 sessions back again)
n.b. : I'm using the proprietary binary driver 190.42 + the grsec patch
(but I couldn't find any message that shows that grsec is involved in
the crash)
