Bug 150164 – dbus-daemon in session mode dies

• Product: Gentoo Linux
• Status: RESOLVED CANTFIX

[Description Zsolti 2006-10-05 06:27:07 UTC]

while trying to get dbus to work with gnome-2.14 i realized that dbus-daemon in session mode launched with dbus-launch dies at least after a few minutes.
i'm starting gnomesession via qingy, but for xdm, gdm and others it seems to be the same. see this thread: http://forums.gentoo.org/viewtopic-t-473749-highlight-dbus.html
first problem is that /etc/X11/xinit/xinitrc.d wont get parsed or dbus-daemon isn't launched, but this should probably go in another report.
so i put "dbus-launch gnome-session" into $HOME/.gomerc.
now dbus-deamon is running at least a few minutes, but then unconditionaly dies.
i could not attach a backtrace or coredump since there is nothing in the logs.
(yes i switched on USE=debug)
this happens for version 0.62-r1 as well as 0.91.

this seems essential to me since many apps are relying on a working dbus in gnome-2.14 and more would in 2.16.

Reopen if you can reproduce it after recompiling with C[XX]FLAGS="-O2 -march=pentium3 -pipe -fomit-frame-pointer"

Created attachment 98846 [details]
emerge info

[Comment 3 Zsolti 2006-10-05 08:29:24 UTC]

still the same with -O2 -march=pentium3 -pipe -fomit-frame-pointer.

system dbus-daemon runs fine though.
maybe i have to rebuild everything with above cflags to be sure...

Run it from console and attach a backtrace, we really can't guess.

sorry but it's running fine on console and also if gnome is started within a shell. mean if i login into a shell and start gnome-session via .xinitrc.
dbus-daemon --session is started prior when i login.

btw. i digged into /etc/X11/Sessions/Gnome. the scripts in /etc/X11/xinit/xinitrc.d seems to be parsed and executed but simply launching dbus-daemon with dbus-launch doesn't work out of user context.
the resulting command should be: dbus-launch gnome-session.
at least with qingy, does dbus work with gdm this way?

Qingy may not source those files, but last I checked, GDM does.

hm, maybe my english isn't so good. what i want to say is, that i think while starting gnome+x+whatever with qingy via the gnomesession script the scripts in X11/xinit/xinitrc.d/ *are sourced indeed*, also the script 30-dbus, but it is useless since only firering up dbus with dbus-launch doesn't work.
theoretically someone has to do: dbus-launch gnome-session to pass the envs to gnome.
but if it works with gdm, i mean if the dbus session daemon is started and stays up then it's probably a qingy only problem.
im back to startx anyway...

So quingy does the wrong thing but you no longer have a way to test?

If you find any issues with dbus and have a way to test. Please reopen with new info.
