Thinkpad T43p no longer able to suspend to RAM (intrepid)

[hunger]

My thinkpad T43p is no longer able to suspend to RAM using latest intrepid kernel and other packages.

KPowersave does not even list the option to suspend to RAM anymore. Suspend to Disk is still listed.

This has worked fine ever since Breezy (with some bugs occasionally breaking things:-).

My hardware is described in detail here:
https://wiki.ubuntu.com/LaptopTestingTeam/ThinkpadT43p-2668

Please feel free to request additional information.

Best Regards,
Tobias

Sounds like Bug #267141. An easy way to test would be to remove the
uswsusp package and then running this command: "pm-is-supported
--suspend; echo $?". If the output is 0, then it is a duplicate of Bug
#267141.

Uninstalling uswsusp makes pm-is-supported --suspend exit with 0 while having it installed the return code is 1.

KPowersave still does not offer suspend functionality, even after uninstalling uswsusp though.

Restart and try again.

Restarting does not help.

uswsusp is not installed anymore but I still can not suspend to RAM.

KPowersave still only offers suspend to disk. The same is true for guidance-power-manager.

can_suspend is false, while the other options are true:-(

Do this in a terminal:
=======================================
. "/usr/lib/pm-utils/pm-functions"
echo $SLEEP_MODULE
check_suspend; echo $?
=======================================

Here is the output:

tobias@chewbacca> . "/usr/lib/pm-utils/pm-functions" ~
/usr/lib/pm-utils/pm-functions:52: no matches found: /etc/pm/config.d/*[!~]
tobias@chewbacca> echo $SLEEP_MODULE ~
auto
tobias@chewbacca> check_suspend; echo $? ~
zsh: command not found: check_suspend
127

I hope this helps...

[hunger (hunger)]

OK, running this in bash (instead of zsh) I get a different output:

tobias@chewbacca:~$ . "/usr/lib/pm-utils/pm-functions"
tobias@chewbacca:~$ echo $SLEEP_MODULE
uswsusp
tobias@chewbacca:~$ check_suspend; echo $?
1

[hunger (hunger)]

... and after uninstalling uswsusp again (reinstalled it yesterday to test suspend for a bit) I get this output:
tobias@chewbacca:~$ . "/usr/lib/pm-utils/pm-functions"
tobias@chewbacca:~$ echo $SLEEP_MODULE
kernel
tobias@chewbacca:~$ check_suspend; echo $?
0

[hunger (hunger)]

Wow, great... after *purging* uswsusp suspend works again. Just removing it did not fix the issue for me:-(

[hunger (hunger)]

Works again, so let's close the issue again.
