Gnome flashback session failed to launch.

I installed gnome-flashback and tried to launch it via custom .xinitrc and ended up with "Oh no! Something has gone wrong"'s greeting.
Tried with DM (lightDM / slim) still give same error. Gnome-shell, Gnome-session work fine. Oh I also dug into /var/log/messages and found log about gnome-flashback get segfault (I am not really sure what it means). I use devuan 32 bit. I have no issue with Devuan 64 bit. Any Advice? Thanks.

Re: Gnome flashback session failed to launch.

I thought segfaults were consigned to history, windows, and silliness?

The last time I saw one was when I used dd to take an image of the system, while live (i.e. dding itself)
Then, while still live, dd that copy back over itself.

Then reboot. Everything looks fine, but every command returned * segfault *

This is really why you should not dd anything that is mounted, and certainly not anything live, unless criminal hacking, of course.

Please share the contents of that file.

Check the X.Org log file to see the actual error messages.

Check the log files for those display managers.

Re: Gnome flashback session failed to launch.

My custom .xinitrc entry is like this:
export XDG_CURRENT_DESKTOP=GNOME-Flashback:GNOME
exec gnome-session --session=gnome-flashback-metacity

It works fine on my other machine.

Please post the segfault log entries here (and a few each side of the segfaults).

Re: Gnome flashback session failed to launch.

I'm sorry for too long on hanging this post. It kind of solved, I just need to export gnome desktop env value and launch metacity with gnlme-panel manually.
It's solved. Thanks everyone.
