Re: [opensuse] Suspend issue

Well, I might have found the culprit : an outdated fdi file in hal.

It is all explained there :
https://bugs.launchpad.net/ubuntu/+source/hal-info/+bug/235284

The patch there did not work for me as it is, so I
edited /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-lenovo.fdi manually.
Anyway the bug reporter has a 6460 model whereas mine is a 7664 one.

What I did :

1 - backup the file

2 - remove all occurrence of 7664 in the file
(prefix_outof="...;7664;...")

3 - add these lines at the end :

<match key="system.hardware.product" prefix_outof="7664">
<merge key="power_management.quirk.s3_bios"
type="bool">false</merge>
<merge key="power_management.quirk.vbemode_restore"
type="bool">true</merge>
</match>

4 - restart hal : "/etc/init.d/haldaemon restart"

5 - test suspend to RAM

I did not change ANY other of the default settings.

If your test is conclusive, I guess it is better to copy the new file in
"/etc/hal/fdi/information", so that it doesn't get overwritten by a
future update.

I hope this will help. Let me know how it goes for you.

Hi,

I have a Thinkpad T61 laptop and use the Nvidia graphic driver.
I think this configuration is pretty common.

However, resuming after suspending to RAM randomly hang on a blank screen.
Sometimes, it finally resumes after minutes, and sometimes I have to cold
reboot.

I could not find the exact issue reported on the net. Does anyone else have
the same laptop here ?

Best Regards.

Check the /var/log/pm-suspend.log file when it fails. If you are lucky
it will show you the cause.

For my Dell Vostro with NVIDIA I had to add the following files.

cat /etc/pm/config.d/nvidia
DISPLAY_QUIRK_VBE_POST=false
&
cat /etc/pm/config.d/s2ram
S2RAM_OPTS="-f --acpi_sleep 1

Your mileage may vary (try modifying the acpi_sleep value)

ps. I have this working, but every now and then (every 30 times) it just
reboots (as if it was not set to resume the suspend)?



I tried your tweaks and other combinations, but no luck.

In the log file, the only noticeable message is :


===== 2008-12-05 20:06:13.197708442 running
hook: /usr/lib/pm-utils/sleep.d/10NetworkManager =====
Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply.
Possible causes include: the remote application did not send a reply,
the message bus security policy blocked the reply, the reply timeout
expired, or the network connection was broken.

I am not sure this is the cause of the hang. Maybe it comes from hal and
its quirks ?

Strangely, when I used Debian on this machine before switching to Suse,
I did not have this issue.

So, there must be a way...
