laptop does not complete suspend

[Jordan Dawe]

Binary package hint: pm-utils

Lenovo x61t laptop running Karmic 9.10 pm-utils 1.2.5-2ubuntu7

When I try to suspend, either via closing the lid or selecting suspend from the logout menu, the laptop attemps to suspend but never completes the suspend. Monitor is off and all input is gone, pm-utils.log indicates it has gone through the suspend sequence. Suspend was working fine two days ago, I noticed this in the morning when I woke up and my laptop battery was dead. Normally on my x61t the suspend light flashes for ~3 seconds before sleeping, now it simply never stops flashing. When I open the laptop lid to attempt wakeup, nothing happens--I have to power off and restart. I have tried to suspend ~ 5 times and it has failed each time. I have tried this with kernel-2.6.31-16-generic and kernel-2.6.31-17-generic with the same result.

Just discovered the laptop will suspend successfully prior to logging into gnome. I booted the laptop, did ctrl-alt-F1 to a terminal and executed sudo pm-suspend successfully. Upon resume, I returned to the gdm login screen and closed the lid, which also suspended correctly. Upon resume, I logged into gnome, then closed the lid, and suspend failed as before.

How about trying to suspend without closing the lid? Does that work?

On the day I submitted the bug, nothing worked. However, yesterday the laptop began to suspend again without any intervention on my part. Works perfectly from the command line and via closing the lid. I have no idea what happened.

I had a problem with this -- Acer Aspire One. Suspend worked under Jaunty. Under Karmic, functioning was sporadic. Sometimes, the laptop would not resume. Or it would resume to the login screen, but not accept my username or password. On one occasion, I was completely locked out. Even a power down and subsequent reboot failed to get me back in to the login screen. At that point I reinstalled Jaunty.

I also have this problem, with 10.04, except once it goes into sleep, it never wakes up.. Holding power actually does nothing, and I'm forced to pull the battery out of my laptop, just to get POST again..

What is upsetting me and really frustrating, is the fact that everyone is ignoring these sleep mode bugs, like the Ubuntu team doesn't care.. Frankly I'm tempted to move to Fedora..

This looks like something I can reliably reproduce ATM on 11.10. If I close the laptop lid on my Lenovo T500 while on AC power, it suspends very quickly. If I close the lid while on battery power, the sleep indicator starts blinking. At this point, the machine starts to get very hot (the fan seems to stop running).
The sleep indicator stays blinking, and the power button does not wake up the machine. I have to hold power to power off completely, and then restart.

I haven't tested pm-suspend directly (vs closing the laptop screen). I'll try that next (just want to finish submitting this before I crash my machine again.)

[John A Meinel (jameinel)]

Confirmed. If I run 'pm-suspend' while on AC power, it suspends correctly in about 1-2s. If I run 'pm-suspend' while running on battery it hangs and stays with a blinking sleep indicator (I stopped waiting after about 1 minute, previous experience has shown no suspend after 10+min.)

I'll attach the result from the successful pm-suspend.log and one from a failing pm-suspend.log.
Looking at them, pm-suspend seems to get to the point where it says:
Tue Nov 1 17:18:56 CET 2011: performing suspend

but then it doesn't actually finish. Does this mean the failure is in a different layer?

[John A Meinel (jameinel)]

The only other obvious difference is that 'fglrx' has 94 dependencies in the failing suspend and 95 dependencies in the successful one. (doing a diff just shows that difference, the timestamp differences, memory allocated differences, and the resume difference).

Please reply if this is still an issue on a supported release.
