kde-guidance-powermanager causes double sleep, memory corruption

[Buck Evan]

Binary package hint: kde-guidance-powermanager

This issues is related to a Kubuntu laptop (Dell B130). The laptop was
originally installed with Dapper Drake, then upgraded to Edgy, and
finally Feisty. The below problems are fairly recent, starting maybe a
month after the upgrade to Feisty.

1. About 90% of the time after I suspend, when I awake the machine it
goes back into suspend mode after about 3 seconds. Simply pressing the
power button finally brings the machine up. Harmless but annoying.

2. About 10% of the time when #1 happens, video memory is corrupted
slightly. I get a bizarre white patch in the upper-left corner of the
splash screen, and a few of my System Tray icons are scrambled.

3. About 5% of the time when #1 happens, the machine just sleeps
itself repeatedly. Usually after 5 or 6 tries it will finally wake up,
but once after more than 10 tries i just hard-restarted.

4. About 50% of the time after #2 happens, I'm left at a full-screen
console with "Starting up ALSA" at the top and no prompt. I can type
things in but there's no responce. Restarting is the only choice.

5. Twice the laptop has been closed and running normally (as per
settings), then gone into sleep mode when *opening* the lid.

WORKAROUND:
Uninstall kde-guidance-powermanager (requires uninstalling kubuntu-desktop, i also uninstalled hal as it didn't seem to be used by anything). The sleep button now only causes a single sleep action, but takes about 10 seconds as opposed to around 3 previously. I believe acpi-support is causing this functionality. I guess guidance caused the first sleep at 3 seconds then acpi-support caused the second at 10 secs resulting in double sleep?

I'm very new to bug reporting, so please give me any diagnostic
commands that you need.

I tried the opposite thing (guidance-powermanager without acpi-support) and again the laptop doesn't do the double-sleep, but it does still have issues with garbled video memory, so that may need to be submitted as a seperate bug. The laptop goes to sleep at about 3 seconds after the button press, as hypothesized earlier.

I've attached some logs from before and after the double sleep issue

I have a similar problem with kpowersave (actually, I was running guidance simultaniously). I have a modified sleep.sh script that may or may not be helpful (please use at your own risk.) This is for gutsy. Basically, it checks for a file called "suspend_lock". If the file does not exist, it creates it and then suspends. After it resumes, it deletes the file. This should prevent double suspends almost all of the times, but no guarentees. I have only tried this once on one computer with one version of ubuntu (gutsy).

Place this attachment in /etc/acpi/sleep.sh (overwrite the existing file.)

I have the same problem with my dell D820 using gusty, as a quick workaround, I just comment the suspend function of kde-guidance and now my laptop suspend and resume allways.

[Luka Renko (lure)]

Can you try attached patch for acpi-support package and confirm it fixes the problem for you?

[fedenunez (fedenunez)]

The patch didn't work for me.

[Ryan Nowakowski (tubaman)]

I have this same issue. It might be related to having 2 user logged in, both with sleep on lid-closed set.

[Ryan Nowakowski (tubaman)]

If i make sure only one guidance-power-manager.py is running, the double sleep goes away. Attached is the script that I run every minute using cron to kill duplicate guidance-power-managers.

I have version 0.8.0svn20080103-0ubuntu16 and I still get this problem. When I and my wife are logged with separate X sessions, and I get two instances of guidance-power-manager.py:
