Activating suspend from power button menu does not work

Status changed to 'Confirmed' because the bug affects multiple users.

I concur, as of 8/27/2012 with all the latest updates, 12.10 has this bug on my Samsung Series 9 np900x4c ultrabook.

Conversely, reboot does not work when activated from the corner menu but does work from the power button menu.

Also happens to me. Ubuntu 12.10 on i386.
1. Press physical power button on Dell 1420n laptop computer
2. Menu appears, select "Suspend"
3. Expect computer to suspend (which does work from gear-like Unity menu and Suspend option)
What actually happens is computer does not suspend, also appears output in $HOME/.xsession-errors:
gnome-session[1921]: libupower-glib-CRITICAL: up_client_get_can_suspend: assertion `UP_IS_CLIENT (client)' failed

I get this after a few suspend cycles. It stops working with that error message on .xsession-errors.

Same problem with the same xsession-error: HP/Compaq NC4200, Ubuntu 12.10

Same here, Dell Latitude E4300 laptop , and tree desktops (one Intel Core2 Quad/ASUS mobo and two AMD Phenom II x4/Gigabyte mobo). All off them on AMD64.

We have this on the Nexus7 tablet and I've seen it on my HP Elitebook laptop, I think it's safe to say this is not a hardware dependent issue.

By the way, if hibernation is enabled, it doesn't work via this menu too.

The error shown in syslog, in hibernation failure is
libupower-glib-CRITICAL: up_client_get_can_hibernate: assertion `UP_IS_CLIENT (client)' failed

For the record, this can be triggered without the power button with

gdbus call -e -d org.gnome.SessionManager -o /org/gnome/SessionManager -m org.gnome.SessionManager.Shutdown

That's easier to do in tests. I have not yet found yet how to synthesize XF86PowerOff with xte (or otherwise).

This bug was fixed in the package gnome-session - 3.6.2-0ubuntu2

Can we get this backported to Quantal please? I don't think this is something that users should be waiting 6 months for the next upgrade to get fixed.

Sure, no problem.

Uploaded to raring-proposed queue for SRU team review.

Thanks pitti!

Same problem on HP compaq 6730b running Ubuntu 12.10 64bit. Pressing power button and select Suspend from the menu
does not suspend. Suspend from the cog (gear) menu works fine.

Error message shows up in both .xsession-errors and syslog.
