standby does not work any more

[aldebx]

Binary package hint: linux-image-generic

Standby (aka Suspension to RAM) does not work any more after updates of the last two days.

After clicking to "Suspend" button the screen becomes black, than prompts me for the password (as if I had just resumed it from standby). After enterning entering the password on the tray appears a balloon text message saying the system failed to enter standby and that I should read the help.

Booting with the previous kernel 2.6.22.13.19 I can enter standby without any issue. However I cannot use that kernel any more because the nvidia-glx-new drivers do not work any more with it (I have to use nv drivers and screen cannot go beyond 800x600)

I cannot say exactly what package is responsable for this issue, however the following packages were installed:
Upgraded packages:
linux-generic (2.6.22.13.19) to 2.6.22.14.20
linux-headers-generic (2.6.22.13.19) to 2.6.22.14.20
linux-image-generic (2.6.22.13.19) to 2.6.22.14.20
linux-restricted-modules-common (2.6.22.4-13.6) to 2.6.22.4-14.8
linux-restricted-modules-generic (2.6.22.13.19) to 2.6.22.14.20
linux-source (2.6.22.13.19) to 2.6.22.14.20
nvidia-glx-new (100.14.19+2.6.22.4-13.6) to 100.14.19+2.6.22.4-14.8
nvidia-new-kernel-source (100.14.19+2.6.22.4-13.6) to 100.14.19+2.6.22.4-14.8
Installed the following packages:
linux-headers-2.6.22-14 (2.6.22-14.41)
linux-headers-2.6.22-14-generic (2.6.22-14.41)
linux-image-2.6.22-14-generic (2.6.22-14.41)
linux-restricted-modules-2.6.22-14-generic (2.6.22.4-14.8)
linux-ubuntu-modules-2.6.22-14-generic (2.6.22-14.35)

By the way Suspension to Disk (aka hibernation) works well.

follows output from syslog right after invoking suspend to ram:

I found that issuing via shell command

sync; echo 1 > /sys/power/pm_trace; /etc/acpi/sleep.sh force

the system correctly enters standby and correctly resumes!
However it remains that using the Gnome applet it does not work as I described!
Do someone have any idea about what is going on?

[aldebx (aldebx)]

executing
Code:

sync; echo 1 > /sys/power/pm_trace; /etc/acpi/sleep.sh

does simply nothing...
no outputs either in syslog and in dmesg

how can I further debug this issue?

here attached is my sleep.sh file, can somebody compare with his? maybe via diff or xxdiff...

Suspend to Ram is also broken for me (Thinkpad X61S).
It was working fine with the -13 kernel version.

As additional hint: Suspend with 2.6.22-14 works "the first" time, but after this, it is crashing.

[aldebx (aldebx)]

the issue was caused by conflict with package 'hibernate'
[code]sudo apt-get remove hibernate[/code]
solves the problem.

however please notice that package [B]hibernate [/B]is required by [B]laptop-mode-tools[/B] for the auto shutdown at low battery levels feature.
