[karmic] ubuntu fails to suspend/hibernate if the session is started from the terminal (startx)

[Katsudon]

Ubuntu Karmic, with all upgrades.

When I login to the text terminal (Ctrl-Alt-F1) and start the GNOME session by "startx", then any attempt to hibernate/suspend result only with a locked screen. After unlocking the following error message shows up:

Menedżer zasilania: Sleep problem
Your computer failed to suspend.
Check the help file for common problems

[ translation: power manager: Sleep problem... ]

The problem does not show up if I login to GNOME from the kdm login directly.

This isn't a problem in Launchpad, so I've added an Ubuntu bug task for it.

Magically, after several restarts, the problem disappeared, at least for a moment. I am closing this bug, if the problem returns, it will be reopened.

@arky: why this bug was set to "Invalid"?

This issue is still seen with the Karmic Beta release, on Lenovo T61. Please let me know if any logs/info are required.

In addition to the above - my session is not started using startx, but normal graphical/gdm login.

I experience a very similar problem on Fujitsu Siemens laptop. I use only graphical login and know nothing about startx...
I also can't neither close system nor restart it! Choosing one of this options from menu results in just logout! The same when I login from gdm using root account (Ubuntu 9.10 Karmic).

Using:
 /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux
   and
 /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux
works without any problems! (of course after su command on user account)

This is not a kernel issue.

When login from the console, libpam-ck-connector will create XDG_SESSION_COOKIE. While you run `startx`, In /etc/X11/Xsession.d/90consolekit, it checks the environment variable XDG_SESSION_COOKIE is already set and will not create a proper CK session.

Try to `unset XDG_SESSION_COOKIE` before `startx` to see if suspend/hibernate works.
