If i kill the ksysguardd process i can suspend or hibernate without problem.

Reproducible: Always

Steps to Reproduce:
Try to suspend or hibernate the pc with ksysguardd running.



I use Kubuntu 10.10 installed on a Samsung N150P netbook.
Comment 1 Dave Johnson 2010-11-09 13:36:06 UTC 
Affects me to on Kubuntu 10.10 with Dell laptop. Killing ksysguardd does the trick.
Comment 2 Geordi LaForge 2010-11-16 03:43:25 UTC 
Any answer ?
Comment 3 Jens Bergqvist 2010-11-18 11:22:30 UTC 
This bug also affects my Asus Pro32A (aka UL30A) running Kubuntu 10.10. My backtrace is very similar to the one previously reported. However, on my system the bug is intermittent and once it's triggered I can no longer kill the ksysguardd process. It keeps blocking suspend until the machine is rebooted.
Comment 4 Joël Schaerer 2010-11-23 00:43:56 UTC 
Same problem here. Pretty painful.

I have no idea why or how to fix.  If you guys have any ideas, let me know.

Hello.
I just updated to kubuntu 11.04 beta, which has KDE 4.6.1.
I also bumped into this issue. Disabling ksysguardd by removing any monitoring plasmoids works, but it's not ideal :-)

To workaround that I just added the file:
/etc/pm/sleep.d/00_local

With the following content:
[code]
#!/bin/sh

# Action script to make sure ksysguardd doesn't interrupt
# suspend or hibernate
#
# License:   GPL-2
#

PATH=/sbin:/usr/sbin:/bin:/usr/bin

if [ ! -x /usr/bin/ksysguardd ]; then
        exit 0
fi


case "${1}" in
        hibernate|suspend)
                killall -STOP /usr/bin/ksysguardd > /dev/null 2> /dev/null
                ;;
        resume|thaw)
                killall -CONT /usr/bin/ksysguardd > /dev/null 2> /dev/null
                ;;
esac
exit 0
[/code]

It seams to work well, at least in my box :-)

ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task.

If your issue still happens with the Plasma 6 replacement, please re-open and we can move this bug to the new product, thanks!
