Dell D420 suspends immediately after resume from lid open.

[Bastanteroma]

Binary package hint: pm-utils

I've been running an up-to-date Karmic. My laptop normally resumes from suspend when I open the lid. A few weeks ago it started going to sleep immediately after waking up, forcing me to resume again by pressing the power button. Wish I could remember more precisely when it changed, but I assumed the problem would just go away. I'm happy to try older versions of things but I'd need instructions.

my Dell Latitude 630 with 23-bit Karmic experiences these exact symptoms. I usually close the lid when not in use, and have it set to suspend. When I open the lid, usually it wakes in less than 6 seconds. However, as Bastanteroma describes, now it goes to sleep as soon as it wakes up. This doesn't happen every time for me, maybe 25%?
I also have a friend who installed 64-bit Karmic on a Dell XPS laptop and it also exhibited the same symptom.

I meant 32-bit obviously. :P

I've been experiencing exactly the same problem on a Dell D420 laptop ever since upgrading from 9.04 to 9.10 beta, and it still exists in a fully up to date 9.10. Let me know if there's more information you need.

[pfaffman (pfaffman)]

Yup. Me too. Has anyone found a work-around?

Also occurs on XPS m1330.

Exactly same problem here on Precision M6300, using debian testing/unstable. Introduced sometime around December 2009. Tried variuos things without success.

Calling pm-suspend from shell works flawless, closing the lid and reopening it causes an extra suspend cycle for some weird reason.

Can you guys check wether it works correct when you type "pm-suspend" into a terminal?

Also occurs on a Dell Vostro 1500. Happens not only when resuming from ordinary suspend, but also from hibernate, where it is particularly annoying (the machine hibernates again).

I tried jugglefish's suggestion of 'pm-suspend' and the results are inconclusive. This cycle only happens once in a while; maybe once every 20 suspends or so. I used 'pm-suspend' several times and it didn't cycle but that doesn't prove anything.
However I'm curious why when I use pm-suspend it doesn't ask for a password on wake. My screenlock is set to kick in after 4 minutes, so I waited about 6 then opened the lid and it went right in. Guess that's a different issue though.

pm-suspend doesn't lock your screen prior to sleeping because it's a backend script that is called by gnome-power-manager. If you suspend from the pointy-clicky method in GNOME (or in KDE) it should lock your screen for you prior to calling pm-suspend.
